Do you open the windows in your home when the weather is nice? When do you decide to close them and turn on air conditioning for the summer?

I open my windows in early spring and leave them open until daytime highs get into the upper 80s. Lately, I've noticed that I rarely see homes with open windows. Does anyone still open their windows to let in fresh air?
Soggy_Yarn@reddit
My AC has been running all year. It’s too hot outside, then the dust gunks up the house. I hate it here
QueenMackeral@reddit
Depends on the window I guess, backyard door has a window that's almost always open. Bathrooms occasionally open windows. But we don't open bedroom or living room windows. My neighbors are super noisy and id hear them all day if I did.
EvangelineRain@reddit
I have no air conditioning, so my windows are open from mid-spring through mid-fall!
12468097531@reddit
Yep! Open them all the time. I run really cold, so it's got to be well into the 90s before I'll close them
lori244144@reddit
Our windows are open if it’s less than 73. I close them if it’s under 55 or over 73.
SociologySeeker@reddit
I was born and raised (and still live) in the United States, and even in the winter, I turn off our heating/central air so I can open all the windows in the house and get the “stale” air out. In warmer months, I tend to use just the windows and not AC or even fans, and always thought that was normal until my (now-ex) boyfriend, who was born in Germany and grew up as a dual citizen, splitting time between the US and DE told me that I was “so German without being actually German” because he had never seen anyone else in the US do that…even his family here, they only did/do it when the are in Europe. I think about this all the time because it is so confusing to me how very different even the same family’s patterns are, depending on where they are.
JulesInIllinois@reddit
Yes. We open our windows in the fall and spring when the weather is nice (not too hot or cold). We rarely open them in winter and summer because it is very inefficient for our HVAC systems. In Chicago, we usually have to run our HVAC all the time in summer and winter.
Mike312@reddit
I'm in Northern Cali. This time of year we have climate control off and windows open, going on well over a month.
Usually we close windows when its below 50 or above 90 during the day. Even during the summer, I'll flush air in the morning if its cooler outside than inside.
sgtm7@reddit
I would probably air out the house once a week for a few hours.
dadsgoingtoprison@reddit
Too much pollen, heat and humidity. I’m in the Deep South of the US.
Trypt2k@reddit
80s? Wtf is that? I like windows open until it's mid 20s or higher. After that it's all AC.
Smart-Airport5781@reddit (OP)
I'm guessing you aren't from the US. Your mid 20s Celsius is the same thing as my 80 degrees Fahrenheit.
tasukiko@reddit
We have ours open most of the time. Only when it is beyond uncomfortably hot or cold will we close up and use the AC or heat. Oh, or I suppose if there is something weird happening outside like smoke or a crazy stink or something like that.
2quila@reddit
I installed an Evap/swamp cooler.. My windows are always open... Got tired of the 1K electricity bills
duabrs@reddit
Nice? Yes.
Scorching on the surface of the sun hot? No.
Mindes13@reddit
Here in Florida there's a small time frame where windows can be open and then that's dependent on any controlled burns in the area
runnergirl3333@reddit
We keep our windows open year-round, but I live on the coast in California. After reading some of these comments about bugs, pollen, heat, humidity etc I’m reminded again why it’s so desirable to live in my area.
The houses are crazy expensive for people who want to move here, but we do get to keep our windows open! 😂 Maybe that’s worth it?!
cryptoengineer@reddit
Don't the open windows let the wildfires, earthquakes, and debris flows in?
2quila@reddit
I think they make a special screen to keep the earthquake out.
Repulsive_Brief6589@reddit
Where I used to live in California (in a forest), yes, the wildfires every summer were brutal. Where I am now there is hardly ever smoke. Like maybe a couple days a year.
Ivebeensued@reddit
Same, and last year only turned on the AC twice
HappyCamperDancer@reddit
Oregon here and same!
Boring_Investigator0@reddit
It depends on what temps you like. I have my windows open if it's under 60° F. So most nights in January. I even had it open on that night it hit 26°. I like being buried under blankets and having it be as cold as possible.
duabrs@reddit
I was just in Florida. That time frame was between 6:00 and 6:05 am.
Familiar-Ad-1965@reddit
That exactly when my windows are open.
Smoke smell in air last night till after 1am so windows closed. Today around 7pm temp was still 95F on covered porch.
Laylasita@reddit
Today it was from 7a to 8a. It's currently 88⁰
birdconureKM@reddit
Too many windowsill plants to be able to open the windows 😅. We are trying to keep the electric bill down (California) so we don’t touch the ac until we need to. But if we open the back door (in the kitchen that lets out to the backyard) and the front door (we have a screen door for the front door that keeps bugs out and the dog in) we can usually get a nice breeze that flows through the house and gets rid of any stale air.
Some_Refrigerator147@reddit
Hit 73 today, 60 now and the windows are still open. I love it, about 90 and I need ac, especially if it’s still hot when I want to sleep.
MickeyBear@reddit
I live in AZ, windows open at night all winter and for storms, shut them about a month ago and haven’t opened em since.
bertmom@reddit
I’m in California. It’s spring and lovely, windows are opened most of the day starting around 9:00am and closed around 6:00pm. In the summer I will have the windows open around 7:00 am and close them by 10:00am to turn on ac. Then I open them again for a couple hours in the evening.
Particular-Move-3860@reddit
I pull my window air conditioners out of storage and install them when there is a prolonged spell of hot weather (80°F or above), which doesn't occur every year.
ReasonableSal@reddit
Yup. We don't have A/C, so we try to be strategic about it, though. Typically, when it's stupid hot, it's best to open windows at night and close everything up during the day. If you see a house that's all shut up, it doesn't necessarily mean they're running A/C; they may just be trying to keep the heat out during the day.
SupKilly@reddit
Don't have AC in our home in Alaska (most don't)
Just a box fan in the window, doing the Lord's work.
No_Button_1750@reddit
Yes. Born and raised in New Zealand and air conditioning in houses is not common so windows open is the standard.
Living in Michigan I absolutely open the windows in spring and again in autumn for some fresh air to circulate through the house when the temperatures are not too hot or not too cold but summer we’re all about the air con and winter all about delicious central heating.
AKlutraa@reddit
Here in Alaska, very few houses have AC. Furthermore, fewer than half our windows open. The rest are fixed.
Yes, we open our windows (which are generally casement rather than sash) when the weather gets warm. It seldom stays warmer than the low 60s overnight, even in June, when there's only five hours of "night," so the windows get closed in the late evening.
Sometimes, though, when we get several sunny days in a row, the upstairs can get into the 80s and stay that way because our houses are engineered to keep heat in. With the sun shining into every room from every direction for over 19 hours each day, from NNE at sunrise to NNW at sunset, it's important to close blinds to keep bedrooms cool enough for sleeping. But it's a dry heat, and a portable fan is enough to make things tolerable.
ImLisaZ@reddit
There’s way too much pollen here to keep windows open.
VioletJackalope@reddit
Yep. Pollen and bugs. I live in a rural area where there’s lots of farmland too. Fly central this time of year.
According-Couple2744@reddit
Same here in Virginia. I pulled the screens off of my windows years ago and most of my neighbors have done the same. To make matters worse, my HOA planted Bradford Pear trees throughout our entire neighborhood. The entire neighborhood is yellow.
Myfourcats1@reddit
I’m in Virginia. It was 90F today. In April. Ugh
PantsDontHaveAnswers@reddit
For me it's mostly got to do with how humid it is out rather than the temperature. It's quite humid where I live so I mostly keep the windows closed use an AC.
msabeln@reddit
I’m in the lower Midwest and humidity control is important in both winter and summer. Right now, there are lots of big flying insects and pollen in the air, and so even if the air is at a good temperature, other unwanted stuff can get in.
My current house isn’t fitted with screens on the windows, and the number of windows are fairly small and often inconveniently located. My previous house, only two thousand feet away, also lacks screens and is incredibly dusty due to its location. So no open windows.
RemonterLeTemps@reddit
I'm in the middle-Midwest (i.e. Chicago), and pollen is a huge problem this time of year (especially from trees). Though we have relatively new windows with screens, screens do nothing to filter out pollen, so the windows stay shut.
That also filters out a lot of the urban noise (loud music, car alarms, buses, etc.) I love living in the city, but I like it quiet inside the house : )
Chicago-Lake-Witch@reddit
Also in Chicago. The pollen is intense right now. And everyone’s apartment building seems to pick up garbage on a complete different day with so much beeping. The closed windows keep me sane. But for like one week in spring and one in fall, I get to have them open and it’s glorious.
Secure-Ad9780@reddit
How can you live without screens? You can easily make them yourself with frames and screens from HD. Mosquitos carry diseases.
brennacedria@reddit
By not opening the wondows
DrGlennWellnessMD@reddit
Humidity honestly determines when I put my AC on first. We'll have stretches where my thermostat isn't rising much but the inside of my house feels so gross and damp that I NEED that AC to clear it up
Impossible_Emu5095@reddit
Yep. In Wisconsin the humidity can be brutal in the spring and summer.
Interesting_Shake403@reddit
Atlanta here, same deal. It’s a shame. Weather is beautiful, would completely have the house open, but everything I own would be green.
Dorkinfo@reddit
I was just thinking about how much more I wash my hands in the spring bc everything I touch is covered in pollen.
At least it is supposed to rain soon.
Familiar-Ad-1965@reddit
Keep hoping.
GlitterRiot@reddit
I thought the first The Pollening was over, but then we got a second The Pollening! I had JUST finished washing my balcony.
cat_prophecy@reddit
I was in Atlanta last spring and waking up in the morning it looked like it had snowed on account of all the pollen.
The only thing that comes close where I live is cottonwood pollen.
Secure-Ad9780@reddit
That cotton wood pollen makes me cough.
Sad_Feature2089@reddit
In Virginia,too. Everything would be coated in thick, sticky, yellow pollen. And..I wouldn't be able to breathe!
abidee33@reddit
I'm in WA and it's similar. My black car is regularly yellow this time of year from tree pollen. I check the pollen tracker before I even think about opening the windows now that I have a portable AC.
ProperBar4339@reddit
Hi, neighbor! We’re in SE VA, and no way in heck am I opening my windows right now. The inside of our house would be as yellow as the outside!
burnednotdestroyed@reddit
Fellow NC resident here. I left something on the patio a couple days ago, came back a few hours later and it was covered in pollen. No way I'm opening my windows!
Bcatfan08@reddit
I was in NC like 5 years ago for work. Went out to my car at the end if the day and it was almost like a yellow fur on the outside. Everywhere except the hand print on the window. Never seen anything like it. I also believe that was the day my seasonal allergies started.
01d_n_p33v3d@reddit
Oak pollen season in Maryland, two to three weeks when everyone's cars, house windows, pretty much any exterior surface, turn green. It's revving up even as I type this.
Also multiple oak cultivars spray the stuff at different times in different locales.
My allergist once told me that the medical literature mentions a "Baltimore Sinus."
Away-Otter@reddit
Screens don’t keep it out? Just curious.
rando24183@reddit
Yeah, there is like a one week period where the pollen is mild, the sun is out but not trying to melt my face off.
im-dramatic@reddit
Yea this year was exceptionally bad in Maryland. Made that mistake and my whole household was sick for 3 days.
bachennoir@reddit
Also Maryland. My car is yellow. That's not how I bought it but the pollen is layering every day.
im-dramatic@reddit
Lol!
MamaMoosicorn@reddit
Fucking truth. That, and the humidity.
Secure-Ad9780@reddit
Yes, my car is covered in yellow pollen. I still like the windows open, and vacuum up the pollen.
Odd-Condition-4773@reddit
I’m in Delaware. The weather and temperature is comfortable enough to have the windows open BUT, the pollen is so bad, that we have to keep the windows closed 😭😭😭
eyetracker@reddit
I hope your cum tree (Callery/Bradford pear) season is over. That's a miserable season.
beyondplutola@reddit
People need to not plant those things.
eyetracker@reddit
Developers like them because they're pretty and grow fast. The fact they stink and don't live long is the problem of whoever they sell it to.
Salty-Impress5827@reddit
I leave them open in the morning until it's as warm as I want the house, then close them and run the air purifier. I have seasonal allergies, but not terribly. My cats enjoy sitting in the windows and it's worth the sneezing to me.
Practical_Celery_878@reddit
Get alot of pollen here in Kansas too. Also, I live on a gravel road that kicks up a bunch of dust. I keep windows closed when nearby farmers are spraying their fields, or planting or harvesting too. So, I don't open up the house often, although I'd love too. Right now I might run both AC or heat day to day.
2PlasticLobsters@reddit
Yep, it was the same when I lived in Maryland. I have enough trouble with allergies without inviting the pollen to drop by for tea.
Funny, last year was my first speing in Washington state, and I had no trouble at all. This year the pollen count has been insane & I had a really bad allergy attack. It seems to be one extreme or the other.
Don__Gately__@reddit
In Wisconsin. We burp the house at least once a day no matter how hot or cold it is.
zzzeve@reddit
And the smell of the Bradford pear trees is enough to not want your windows open!
captainstormy@reddit
Right, I went to get in my truck this morning and it was covered in a yellow layer of pollen. It wasn't even parked under a tree or anything.
KPinCVG@reddit
The pollen is so thick that it turns my asphalt driveway yellow. If you're outside of the USA, an asphalt driveway is black.
Not only is the pollen thick, it is also sticky. So there's no point in just hosing off the driveway because it would require a pressure washer. Likewise, if it comes in the house it's not just a layer on the furniture that I need to wipe off. It's a layer of sticky on the furniture that I need to scrub off.
GlitterPapillon@reddit
I’m in Arkansas and currently have a thick layer of pollen on my car. No windows are allowed open in our house because my allergies are terrible. Now if it’s 50 or 60° F in January I’ll open them.
Cassedy24@reddit
Same here (SC). I might open the windows if we get a nice day before the pollen (so January or February) or once it cools down in the Fall, but only if the humidity is low.
NekoTheSpookieCat@reddit
Fellow NC pollen sufferer. During pine pollen season my black cats went outside for the day and came back looking like tortiseshells. Our green car looked positively radioactive. The pines look like they’re smoking. Every pond has a yellow scum floating on it that makes you wonder if you were teleported to a toxic waste dump.
So, for a VERY brief window of time before pollen season, maybe a week of being able to open windows. I get more ‘air time’ in the autumn.
triangleking@reddit
Yep. Also from NC. I open my windows in the fall but never the spring
ThroatFun478@reddit
Where I live in nc, the fall is just as bad as spring with ragweed and other grasses. Makes all of us sneeze and cough, and the surfaces grimy. You can crack a window a little, maybe right before it's time to turn the heat on.
Jennferno4150@reddit
Same for us in Virginia
kitchengardengal@reddit
Same here in Georgia. The month that the air is most pleasant also happens to be the month of full time pine pollen.
Azadehjoon@reddit
I'm also in NC. Between the pollen and humidity, I never open my windows.
No-Kaleidoscope-166@reddit
I'm in NC. Pollen is worse in the morning. I mainly open windows at night for some nice, cool airflow and shut them in the morning. As long as it's a cool night.
holymacaroley@reddit
Agreed.
Dangerous_Prize_4545@reddit
We have our windows open some at night, esp after a rain. But yeah, pollen. Also NC
Tenos_Jar@reddit
Depends on your definition of "nice". Right now where I'm at summer hasn't set in yet. So the heat is off and the AC hasn't been turned on yet. Still using windows and cross breezes to manage things.
Once the daytime highs are consistently 80F+ and we can't get the house to dump the excess heat load overnight then we'll seal it back up for the summer.
I'm in the northern plains so we'll get heat/humidity from mid-May through late September/ early October. That's when we'll go back to passive thermal management until daytime highs are consistently in the 60s at which point we'll transition back to heating.
My personal barometer for the exact timing has to do with sleep comfort. When it gets consistently too hot to sleep then AC. When it gets too cold. Heat.
Fire_Mission@reddit
The windows in my house have never been opened.
Independent-Yard-834@reddit
I don't even know if my windows are capable of opening lol. But I have cats that don't appreciate the life i give them and would escape so that may be the main reason why I've never even thought to do it
breebop83@reddit
I love having the windows open but unfortunately nice days and high pollen count days tend to be the same here in Ohio. It’s pretty rare to get a day that isn’t too hot or cold outside of peak allergy season. I’m allergic to tree mold as well so even fall isn’t a great time.
Our house is also a bit weird and pretty much impossible to get a cross breeze in. There are walls in the way for all of the N/S windows and the only east facing windows are in the garage. The front of the house is basically open concept with living/dining/kitchen and the bedrooms are down a hallway that jogs around the front bathroom. I would risk the runny nose if we could get a nice breeze but we just can’t so I open the front door every now and then and put a fan in front of the screen if I want some fresh air.
LustfulEsme@reddit
I rarely open mine anymore. Spring and fall I am constantly switching between AC and Heat on my system. We have too many poor air quality days, too many windy days with dust blowing, too much noise pollution ànd crime of assaults and robberies have risen. I keep everything locked up tight. Even doing yard work, cannot keep garage door up, things would get stolen and I live in a nice neighborhood.
birdfriend2013@reddit
I hold out as long as possible before putting in my window AC. Sometimes I can make it until July, sometimes I break in May. As long as it's cool at night (below 70) I'll go with open windows. I don't like air conditioning if I can help it. I'm in NY.
Only_Presentation758@reddit
Unfortunately the windows in my house require 2 strong men to open them. We also get humid muggy weather, pollen, and insects immediately following chilly weather, with sometimes a difference of 30 degrees from morning to late afternoon. So it’s usually either heating or AC in the house and just going outside when we can in nice-feeling weather.
WildMartin429@reddit
Rarely. Even if the temperature outside is nice often the relative humidity is too high and it would make the inside of the house muggy. Also when the outside is perfect and I would love to open the windows there's often a lot of allergens such as tree pollen in the air which I don't want to open up the windows because I don't want a coating of yellow dust on everything in the house. So on those super rare occasions where the weather outside is a nice temperature, the humidity is low enough, and the plants aren't belching tons of pollen into the air then yes I will open up the windows.
Sweet_Cinnabonn@reddit
We don't have that season. Last week it was in the 50s F. Way too cold for open windows. Yesterday and today it was over 90F.
LeSkootch@reddit
In South Florida here and I open my windows when it's cooler and dry outside. Maybe ten days out of the year. I love when I can. Going to sleep with a window open when it's cool out is a wonderful thing.
Wallaroo_Trail@reddit
Won't you wake up to a bed full of lizards and gators?
smwisdom@reddit
Window screens.
Though I dont keep mine open overnight because even with the screens, mosquitoes still manage to find their way in.
Wallaroo_Trail@reddit
I find it difficult to believe that a gator would be deterred by a bug screen, but I can't prove it.
Ana_Na_Moose@reddit
A bug screen might not deter a gator, but the elevation of the window off the ground is likely deterrence enough.
AcingSpades@reddit
Nah they like to climb. Several times when I was growing up in Florida a friend showed up at my house 20min after the bus dropped them off not because they wanted to play but because a gator climbed their fence and they couldn't get inside so they needed to use your house phone to call their parents.
SnazzleZazzle@reddit
Reason #431 why I’d never live in Florida.
CountessofDarkness@reddit
Right?! I had so many reasons..and never had gators even occurred to me. Florida sounds wild.
iamgladtohearit@reddit
I am in South Florida and I have encountered gators plenty of times, they do not bother me at all. You do have to be cognizant of small animals and babies/children next to the water but that is only because some alligators have been hand fed by idiots here and they started associating humans with being given food, so they will think you are offering up a morsel. Alligators are naturally chicken shit and are exceptionally lazy, I'm more afraid of the wild pigs (boar). Crocodiles though, I don't fuck with the crocodiles, but they are significantly more rare, I have never seen one in the wild and only one of my friends within my social group ever has.
LeSkootch@reddit
Depends where you live. I'm in a very developed area very east so we don't have a lot of canals running through. The intercoastal waterway is close but thats saltwater and the only predators you have to worry about are the pedos on their boats. They are brazen and congregate on the island but do find there way to my side often enough.
When I lived a bit further west I used to see gators and even manatees swimming in the canals by my house. Had a whole pod (sounds right but not sure) of manatees that used to hang at the canal right behind my house.
LeSkootch@reddit
As long as you hide the meth the gators will leave you be.
smwisdom@reddit
I suppose I've never had a Gator attempt to climb through my window, whether the glass was closed or not..
I suppose anything is possible though!
Dawk1920@reddit

Competitive_Ad_7415@reddit
Your right, but One on it's own has trouble getting high enough to get through. But when they click up in pairs or trios they boost each other right in. Sometimes I swear I hear them plotting thier attack plan
DizzyFly9339@reddit
When I lived in Florida I would sleep with my patio door open when it was nice out because the patio was fully screened.
Until I woke up one morning with a lizard in my hair. Door stayed closed after that.
LeSkootch@reddit
In my neighborhood I'll just wake up to the sound of a bunch of cats either mating or killing each other.
permalink_child@reddit
Why you looking at/in windows?
Nyxelestia@reddit
I live in Los Angeles, so winter is rarely that cold. My apartment is tiny but has tall ceilings, I have a ceiling fan, and all the windows face north (so never in the path of direct sunlight). For a few weeks in the winter when it is very cold, when it rains hard enough (or drizzle + wind), or when the outside temperature gets super hot (like +95 degrees), I'll close the windows. Otherwise, the rest of the time I just leave them open.
Alycion@reddit
No. I’d love to. But where I’m at in Florida, when it’s nice enough to open the windows without oppressing humidity, the pollen is so bad, the inside is yellow from it within 2 hours. A/C all year long except our cold spells.
Zaidswith@reddit
We're already in the 80s.
Myfourcats1@reddit
It was 90F today. Everything is covered in pollen. We’ve passed pine pollen. Oak pollen did its thing. I think what’s hitting me now is cottonwood. My sinuses are displeased.
Repulsive_Brief6589@reddit
I leave my windows open 24/7 as much as possible. I don't shut them for summer and I don't have air conditioning. I shut them in winter but still air out the house daily.
West_Guidance2167@reddit
My home would be covered in a yellow pollen dust if I left my window open right now. My white car looks like a highlighter. I couldn’t imagine wanting to breed that in all day.
Library_IT_guy@reddit
Never. Pollen and bugs. I don't have faith in my screens.
Flashy-Specific-4083@reddit
Open when it’s between 56 and 70 outside. Once it causes my home temps to go above 71 that’s when I switch to AC
Glittering-Silver402@reddit
I leave them open until it becomes uncomfortable to keep them open
Appropriate-Food1757@reddit
I go be the smell of the air, the AC and heat are on a program always
Born_Kaleidoscope587@reddit
I'm always opening up my windows when it's nice outside. But when the breeze is stopping, or it's getting too hot or cold then they close and it's time for the thermostat to help regulate temp. I just love my fresh air
blck10th@reddit
In Chicago I like the coolness we’re having today. But when it’s humid and in the 80’s + I want the air on in the house. I don’t have AC at work so it’s a nice treat when I get home
phylbert57@reddit
I used to open windows until my pollen allergies got too bad to tolerate it blowing into into the house.
AtrumAequitas@reddit
Absolutely. I turn on the AC when the house stays in the 80s.
tilario@reddit
southern new england checking in: the windows were open earlier this week. we were in the 70s and low 80s. now they're closed. we're back in the 50s. but the heat is turned off.
i have ceiling fans so once summer comes around i generally keep them open except for a few days here and there when the humidity and heat get too much. then i'll go AC. it's maybe 7-10 days tops all summer.
by end of September they start to close again.
Pitiful_Lion7082@reddit
If I don't have the AC or heater on, the windows are usually open. If the house gets uncomfortable and no one can sleep, worried get cussed and the AC goes on.
caseygwenstacy@reddit
My apartment has awful insulation. It somehow is super good at keeping in heat, but awful at the cold. I have been trouble shooting the AC with management and maintenance for two years. This is the third summer it is 80 f in my apartment while being in the 60s outside. If I open up a window, it isn’t going to cool the house, it’s going to make it hotter somehow. I know because I have tried. The temperature just keeps going up even though it should go down from the breeze.
Ok_Orchid1004@reddit
Yes we always have windows open when the weather is nice. A/C goes on when the temperature hits 80°F inside and the humidity is above 60%. Usually I can just feel it, but I do have a gauge which shows both. A nice breeze going through the house can also help keep the A/C off.
SMKnightly@reddit
I would open them in the morning, close by midmorning, and open again in the evening once it’s cooled off again. The house will keep the cool it pulled in longer with them closed midday.
Other days, I don’t feel like going to the effort and leave things closed up. But I don’t get warm easily either
On_my_last_spoon@reddit
Our house is 80 years old. We don’t have central air. We have window units that are stored in the garage from September/October to May/June
So more often than not we open windows over AC
Weary_Boat@reddit
Winter in Florida can be magical; when I was working I'd often leave my windows open all day (when the temp was 60s-70s) and when I returned home it was so fresh inside that it felt great. Now I'm retired and I open them a lot whenever it's nice out.
GreenBeanTM@reddit
Yes we open the windows when it’s nice out, and we close them before the temperature outside gets hotter than inside as we don’t have AC in my house.
RelativelyRidiculous@reddit
Most people are at work during the day and only home overnight. You can't leave windows open while you're gone all day. Back when everyone in my house was at work or school all day we rarely opened the windows. Now my husband and I are work from home we open them during the day.
LA_Nail_Clippers@reddit
Not that much. My wife and one of my kids has outdoor allergies, and one of our neighbors smokes weed at almost any hour. We also live about a mile away from a major freeway and studies show that air pollution even at a mile away can have negative effects especially around rush hour.
But a cool late evening breeze, I'll definitely open up the house to air it out if it's stuffy.
BeeinCV@reddit
I live in Southern California near the Pacific Ocean, I have windows open day and night nearly all year long. Sometimes in the summer it can get humid and hot in the afternoon so we will close up and turn on the air conditioner (about 2-4 weeks), I don’t think the heater came on even once this year.

I have a narrow heat comfort zone. Like, 60s or colder is my comfort zone for "nice" weather. If it's warmer than 75, I'll probably close the windows and have a fan going, though I might push it to 80. It stays fairly cool in my house, but I live with someone who thinks 70 is freaking freezing.
I only like hot weather if I can hang out in some cool water.
I live in Oregon, in a moderate climate valley, and I was born in Seattle, Washington.
Extendyourtrotter@reddit
I open the windows in April and close them in October, barring some unusual weather. I don’t have AC and do have deep overhangs that keep most rain out. I’m in the mountains in NC.
smokiechick@reddit
Despite the pollen allergies that are rampant in my house, after it thaws, the windows are all open to air out the house. We usually just use the windows until it is either too hot or too humid. As northern New Englanders, those numbers are pretty low.
whiteorchid1058@reddit
Absolutely. Early mornings or late evenings in the true summer. All day when I'm home when it's sweater weather
BoopleSnoot921@reddit
When it’s nice (60-70), yes.
Anything above that is too hot and the AC goes on.
StutzBob@reddit
Once in a while, but not regularly. I have a heat pump and just keep the thermostat between 68 and 72 year round.
Sleepdprived@reddit
If i know it is about to rain, I open all of the windows and let the pressure change suck all of the stale air out of the house and blow fresh air through until it starts raining hard.
scr33ner@reddit
As much as I would love to, I don’t due to pollen.
greatkerfluffle@reddit
I’m in Texas. We’ve been in the upper 80’s since February 😂
Electrical_Stage_610@reddit
I live on the Oregon coast. Our summers are MILD. Like, it almost never gets over 65 (18ish in Celsius), even in the summer. Almost nobody here has an air conditioner. I have my windows open anytime it’s over 50 F.
Efficient_Wheel_6333@reddit
Not really save for the enclosed back porch and even then, the weather has to be in that sweet spot of just hot enough and not all that humid for me to even hang out back there. My house isn't really set up well enough to open the windows in nice weather (and there's at least one that needs fixed, as there's some sort of problem where, if it weren't taped shut, we'd be getting all sorts of insects through there, not to mention a leak letting in cool air in the winter).
scandicsiren@reddit
I live in Hawaii, so my windows are open all day year round. The only time they close are if rain is coming in. I don't have AC so it also helps with breeze.
scooterv1868@reddit
Phoenix here, we open them whenever it gets below 75° even if that is at 3:00 a.m. I live in a mid rise.
LukeSkywalkerDog@reddit
I open the windows whenever it is below 70°. Except in winter of course. When it gets to be 100°, AC is on 24 seven.
sean8877@reddit
I live in Georgia and we leave some of the windows open all summer and most of the winter. I turn the air on just enough to avoid mold but I like hot and humid weather so I don't mind it being 82 in the house. We keep it at 74 in the winter and still leave a few windows open in the upstairs. Yeah I know we're weird.
SleepyD7@reddit
We do ours.
LopsidedGrapefruit11@reddit
I open my windows every morning and only close them if it’s hot. It cools down at night where I live so I usually open it at night to let in the cool air. If it’s really hot we turn the AC on at night.
Sugah-mama21@reddit
We don't even consider putting in A/C usually until close to July. We only have window units where I live.
InevitableRhubarb232@reddit
Yes. I will open them in November through early February. In early February I turn on the AC but I will still open the windows at night when it drops below 75.
MrWhite_Sucks@reddit
I try to avoid running the A.C. until absolutely necessary, which is usually around 29-32 Celsius. The heat I also keep off until we are consistently down around 10-15 Celsius. Windows open also keeps the house smelling better!
Bastyra2016@reddit
I have a large screened porch and it’s normal for me to leave the door open from after pine pollen season to not quite scorching season (maybe 3 weeks) in the spring. I also leave the door open in the fall for about the same amount of time. I don’t bother to open the windows because I don’t get much ventilation through them.
Efficient_Advice_380@reddit
Yes, I personally have windows open when it's between 45° and 80°F.
CraftyFraggle@reddit
Lots of people talking about bugs. Does no one have screens on their windows? Screens are standard here.
abidee33@reddit
Lots of houses in Washington don't have screens, much to my surprise. Because a lot of houses also don't have AC. We have spiders and bugs though.
AtaracticGoat@reddit
I had to put a metal mesh screen at the top of my chimney. I have a gas fireplace and the pilot was letting off enough heat to attract insects, especially stink bugs, to come down my chimney and make themselves at home.
send2steph@reddit
There are bugs here that fit through the screens. I have maybe a week or two in the spring and maybe a week or two in the fall of it it makes sense for windows to be open. I have geothermal so it costs the same winter or summer to run the ac / Heat.
Team503@reddit
Window screens seem to be a uniquely American thing in my experience. I WISH I had them here in Dublin.
devilbunny@reddit
House is about 25 years old. Not only do we have no screens, we don’t even have openable windows except where required by fire code as emergency egress.
CraftyFraggle@reddit
I don’t think that’s an age of your house thing.
devilbunny@reddit
Older houses would have openable windows. It absolutely is a factor of age - it was built after central heat and air became standard.
I never used them anyway, though. On the rare days it’s pleasant enough, pollen and bugs would make it a no-go.
CraftyFraggle@reddit
Outside of those in high rises, I’ve never been in a home where the windows don’t open.
Old, new, and in between.
That was my point.
jmajeremy@reddit
I think it’s more of a region thing than an age thing. Where I live houses have had screens for at least 70 years, and having windows that can’t open is practically unheard of.
devilbunny@reddit
It’s too young. Built with central HVAC in mind.
The pleasant week in spring is pollen time. The pleasant week in fall would invite bugs. Otherwise it’s either too hot, too cold, or (especially )too humid.
FeelingPlayfulNow@reddit
That's not even a very old house. I lived in a house near the gulf coast built in the early 70s that not only had screens over the windows, but also had a whole screened in back porch. It wasn't in a rich neighborhood, either. It was a small single story house next to an airport. I'm especially surprised you have windows that don't open.
DrGlennWellnessMD@reddit
Maybe they mean little gnats? Those fuckers don't get stopped by screens
CraftyFraggle@reddit
One poster referred to bugs of all shapes and sizes.
Others just referred to bugs.
kimchipowerup@reddit
Can’t afford AC, so open windows and a fan are the plan.
Lefaid@reddit
Never. It would let the bugs in!
Most places I lived in the US didn't even have windows that would open.
Seakrits@reddit
Anywhere from about 65F-75F I will open the windows. If the high is going to be around 80F, I'll leave the windows open and run fans for circulation. If the high is going to be closer to 85F and above, I'll open the windows in the morning and get cool air inside and circulating, and then close the windows and drapes when it gets around 75. I try not to turn on the AC until the temps are consistently 80F+.
That being said, if the house is still 75F at night, I will sometimes turn on the AC because sometimes even with the windows open at night, it doesn't cool down fast enough to sleep comfortably.
Oh-THAT-dude@reddit
We live in a place where opening the windows in summer is usually sufficient (thanks to sea breezes).
In 19 years we’ve had ONE summer that had a heatwave sufficient to wish for AC.
SaltyTrollop@reddit
I have my windows open all year round, whether it's hot or cold. Unless it's raining or snowing so bad that I'm afraid it's going to get into the house, my cat insists upon being able to chirp at the birds so I deal with it
Sky14318@reddit
Every window and door is open in my home until it’s gets close to or over 100° outside. And sometimes even then. If it is sweltering hot outside, I will sometimes close up the house and turn on the one small window AC unit that we have.
Successful-Safety858@reddit
I was so excited to open them up. Then I had to close them again because a neighbor in my building was smoking right outside the bedroom window.
BeerWench13TheOrig@reddit
Usually the few nice spring days that we get where it would be nice to open a window are accompanied by the great pollening. Neither my allergies nor my clean home appreciates all of that yellow.
We do get a few days in fall where we’ll open the windows while we sleep, but they’re few and far between.
Unlikely-Low-8132@reddit
Air conditioner, What is this air conditioner you speak of, we open the windows, close the drapes and turn on the fans, when it gets hot.
Deep-Hovercraft6716@reddit
There's no need to turn the heating or air conditioning on or off in most homes. They just automagically run on demand as needed based on the temperature the inhabitants set.
Around here in the spring and fall. It is not unusual at all for your heat to run in the early morning when it's pretty cold outside (40f) and then your air conditioning will run in the afternoon when it's hot (80f).
This kind of temperature fluctuation is pretty common and drives the tornadoes.
madelinenicoleee@reddit
Yes I open them, and no I never close them once it is summer. I do not have AC. I get the big box fans and a cross breeze going.
Chemical-Mix-6206@reddit
Mine are open right now. I almost caved & turned on the a/c today, but a cool front is coming in tonight so we get a couple more days of nice weather. Once it gets too hot, it'll be a/c all the time until fall. Have been saving up so I can cover the power bill all summer.
aricberg@reddit
Sadly, my partner and I both have terrible allergies, so the small window (pun intended) where it’s nice to have the windows open usually coincides with the height of allergy season. So no, we usually end up going straight from heating to AC.
ditched_my_droid@reddit
I watch the dew point. Once it gets above 60, it's time to turn on the AC
AlmiranteCrujido@reddit
We're in a part of California with a moderate climate, and have a house with an unfortunately high amount of solar heating.
Windows open in the morning, and are open all day most of the year. Fans go in if it's over 75 in the house, which it often is.
If the fans can't keep it under 80, the AC goes on, but that's pretty rare around here.
FlyingMitten@reddit
Yes, but its all about the dew point.
Many people leave their homes closed and the HVAC set to full auto, but those are the homes you hear the AC running on a nice cool 50F day. They must not like money or nature.
Aprils-Fool@reddit
Why would the AC run if it’s 50°?
hx87@reddit
If you're like me, because you live in an old factory building with massive clear glass windows facing southwest, even the best interior window treatments can only get you so far, all the windows face the same direction so there is no crossflow, and you can't put on any exterior treatments because the local historic preservation board are full of asshats who don't live in historically preserved buildings.
lantech@reddit
Actually just dehumidification probably
Aprils-Fool@reddit
That’s all I can think of. Air movement and humidity control. They made it sound like people are cooling their houses when it’s cool out.
FlyingMitten@reddit
They do..... people are using AUTO mode far too much
Aprils-Fool@reddit
I thought auto mode just kicks on the cooling when the house goes above a certain temperature?
FlyingMitten@reddit
Auto will auto switch between heat and cool. Never seen a system that only autos in one direction.
myshellly@reddit
Mine does. I have to select heat or cool first and then select auto.
FlyingMitten@reddit
I'm referring to auto select of heat or cool. Not auto once in said mode.
Too many autos.....lol
myshellly@reddit
Mine doesn’t have auto select of heat or cool as an option at all.
FeelingPlayfulNow@reddit
Most thermostats are manually set to heat or to cool and "auto" cycles just the heater or just the cooler to stay within a couple of degrees of the target temperature.
FlyingMitten@reddit
Because their house is closed and warm inside. It can be 50 outside yet 75 inside.
Aprils-Fool@reddit
How did it get to 75 inside? And then they’re cooling it down? So like, cycling heat then AC?
FlyingMitten@reddit
Electronics and bodies, and residual heat from previous days. It can be 80 during the day them 40s at night.
Aprils-Fool@reddit
Right, but why would the AC kick on if it’s only in the low 70s in the house?
FlyingMitten@reddit
Because people set their house to 70? Inside temp isn't outside temp
Weightmonster@reddit
In my experience, you set the A/C to a certain temperature. It won’t run if the room temp is already lower than you set. (Some might start up a heater, if you set it that way).
FlyingMitten@reddit
That's the wasteful way. AUTO mode will actively switch between heat and AC.
Spring and fall months you can cool a house a night, close it up, and stay cool all day while it warms during the day. Zero need for the HVAC.
But, if you have the house set to auto mode it will heat and cool the house during the same period. Totally wasteful.
BoopleBun@reddit
I honestly don’t think that many people have systems where the heat and AC are part of the same unit, though? At least most places in northern states I’ve lived don’t. (We have window units for AC, so definitely two different systems at our place!)
Then again, the one place I lived that did have the systems integrated was pretty new, so maybe that’s more of a recent build thing.
vwsslr200@reddit
Nationally, 67% of houses have central AC (75% for single family homes). 17% primarily use window units, 2% portable units, 1% ductless splits, and 11% (mostly on the west coast) don't use AC at all. And of course the central AC percentage goes up for houses built in the past 60 years.
There are some cities, particularly in the northeast with older housing stock, where window units are the norm, but nationally it's very much the minority.
BoopleBun@reddit
But is that just for central air or central air and heat integrated into the same system? Because some places I’ve lived they’re on different systems, even if there’s central air.
I’m honestly surprised it’s so high, either way! I’ve lived all over the place in the US, but l suppose the majority of the time in the northeast, so I’m guessing that’s coloring my perspective.
vwsslr200@reddit
73% percent of US homes have forced air heating. Virtually all houses with central AC and forced air heating will have them combined into one system.
It's only the tiny minority of the country with hot water or steam radiators (7% of houses) that have central AC as a separate system. Again, it's one of those things that's fairly common in the northeast but basically unheard of in the rest of the country.
It should also be noted though that even with central AC and heat being separate systems, they can still be controlled by the same thermostat which is a relatively common setup.
BoopleBun@reddit
Maybe it’s all the places I’ve lived has just been pure luck or something, but I’ve legit only had this in one place I lived as a teen/adult, and it was a fancy newer building in MD. (I can’t remember all the ones as a kid.) IA was baseboard with a wall unit AC. MN was the same. PA was baseboard with window units, ditto WI. NY was a few different areas - radiators, baseboards, radiant, but all separate from the AC. (Also usually window units.)
I mean, if only 66% of US houses have central air, even if most of those overlap with central heat, once you take out the 5% or so that don’t have ANY heat because the area is too warm for it and account for the folks that don’t have overlap it’s not like it’s almost every home or something. Like, yeah, 50-60% would be the majority, sure, but I wouldn’t call the amount of people who don’t have a combined system a “tiny minority”, especially since that works out to millions of homes.
vwsslr200@reddit
To be clear, it was just hot water radiators that I said was a tiny minority of houses. I think it's fair to say 7% is a tiny minority.
Separate heating and cooling systems of different varieties (such window or wall units mixed with heat only systems of various types) are a lot more common. Still a minority, but not a tiny minority by any means.
BoopleBun@reddit
Ah, I see that with the radiators. I misread, thank you.
I think, seeing the numbers now, a shared AC/heating system is much more common than I expected (I would have said like, 35-40% or so of homes, tbh) and much less common than the other commenter thinks (“any home that has four seasons built in the 70s or newer”). So thank you for the additional information.
FlyingMitten@reddit
How many homes built after the 70s are using base boards, wood stoves, fuel oil, etc, as their heat? Not many I suspect.
BoopleBun@reddit
The house we’re renting right now was built after the 70s, and it has baseboard heat. A ton in our state in the northeast do. (I only know because we’ve been looking to buy and I don’t like the baseboards. They’re annoying for furniture and ours are electric and older so they cost a fucking fortune in the winter.)
My folks have radiant heat, and theirs runs off fuel oil. (And no central ac, just 2 mini splits.) They also have a pellet stove to supplement in the winter. Their house is less than 20 years old. I have a fair bit of family in NY, and a lot of the ones upstate use fuel oil heat.
Like, looking up the stats, it looks like it’s a lower percentage of houses than I originally thought, but that still works out to millions of homes because the country is so big. Not the majority, but millions of homes isn’t what I would call “not many” either.
FlyingMitten@reddit
All depends on region....but any home that has all four seasons, built in the 70s or newer, and gets over 80F will have central HVAC.
BoopleBun@reddit
I’ve lived in a whole bunch of places that fit your description that don’t have central HVAC. Even where we live right now, alas.
djsuperfly@reddit
Not necessarily. Because even if it's say 50-55 out overnight, there is likely 85%+ humidity. That's a lot of humidity to be letting in for 8-9 hours while I sleep. Then I'm waking up and shutting it all in? Nah.
FlyingMitten@reddit
Hence why dew point was my first remark. Everything hinges on that.
djsuperfly@reddit
Sure, but if humidity is sitting between 85-90 percent (which it frequently is in most of the SE overnight, except maybe winter) you're not below the dewpoint. And humidity should never consistently be over 60% in your house.
FeelingPlayfulNow@reddit
If you have an A/C that can automatically switch between heating and cooling, generally you set the heating temperature significantly lower than the cooling temperature. The recommendation for energy conservation is heat to 68° and cool to 78°, it doesn't immediately switch to heat as soon as the house starts cooling off overnight.
FlyingMitten@reddit
Depends on the thermostat. Some have dual set points and some don't.
Either way, I've heard AC running in our neighborhood when it's pretty cold out.
Buckeye3327@reddit
Are you talking about the switch that says “auto” or “on” on the thermostat? Because that’s the blower mode setting. On will have the blower motor constantly moving air in the house (can be pretty beneficial in some situations) auto it will only come on when your actively heating or cooling. You have to switch between heating or cooling on every thermostat I’ve ever seen
vwsslr200@reddit
No, the auto setting on the heat/cool switch. Not all thermostats have it.
FlyingMitten@reddit
I'm talking about the auto setting for switching between heat and cool mode.
Weightmonster@reddit
IDK I don’t have an auto mode.

When it's comfortable to have the windows open, I open them. When it's not, I close them. Same with heat and AC.
What kind of answer are you looking for, like a specific temperature range? Humidity, precipitation, wind, and noise outside can also play a role.
HappyCamperDancer@reddit
I open ALL my windows every day for about 5 to 10 minutes. I like airing out the house, even if it is really cold or hot. Then I close them. If it is "temperate" temperatures (between 50 and 80) I will crack my windows to get a little fresh air all day.

San Francisco Bay Area. We leave them open as much as possible.
badtux99@reddit
When we get the cool Delta breeze in the evening I down all the windows and let the house cool soak overnight then close the windows in the morning and then turn on the AC set fairly high. it usually isn't until mid afternoon that I actually need the air conditioning.
On nights the air is absolutely still I just leave the AC on. It uses less power turning on occasionally than running a whole house fan continuously all night.

Angelawina@reddit
My bedroom windows are almost always open, until it gets to 70, then I close them and turn on the ac. But I hate being hot, and we had chinchillas for years, and they shouldn't be above 70. Now it's just how I am, 1 year after losing my last chin.
ChemicallyAlteredVet@reddit
In the Upper Peninsula of MI. As soon as it’s 45 degrees out the 2nd floor Windows are open. As soon as it’s 58-60 main floor windows. We don’t have central AC but when the daytime temps reach 72 or so we put window unit AC’s in just the bedrooms because even with 55-60 at night our upstairs isn’t cool enough to sleep.
But we open all main floor windows as soon as the sun goes down and run fans until dawn. Then we close them and the blinds to keep the cool inside the house during the day. It maintains between 67-73. Unless it’s really hot and the nights are getting below 67. Then it’s hot in this house. But our basement stays 50-60 year round.
chihuahua2023@reddit

7GrenciaMars@reddit
77 degrees outside is 80+ degrees inside, at my place--too hot for me. It's gotta be in the low 70s for me to open my window.
botulizard@reddit
In the spring, usually yes, although sometimes I turn it on in summer because I live on the second floor with a big west-facing window, so in the evening when the sun makes its way into the western sky en route to setting, it's beaming directly into the window and my apartment gets wicked hot if I've forgotten to close the blinds or if I neglected to do it in time. Once it's dark I'll open the window and turn the air conditioner off, provided it's not humid. In summer I'll use the air conditioner most of the time, but might still open the window at nice if it's coolish and not humid.
emmasdad01@reddit
I close them as soon as it is hotter outside than I want my house to be inside.
Roborana@reddit
Same here .
My parents' house has a fan in the attic that helps keep the temps tolerable so they can delay using the AC longer than we do. I have been thinking about getting one because I like having the windows open but really can't stand how stuffy the house gets even just in the mid 70s.
FalseCreme@reddit
I had a house with an attic fan once and I loved it. We had central air for when it got really hot, but I loved being able to suck the hot air out through the roof vents and cool the house almost instantly.
TheRealThordic@reddit
Heat build-up in the attic isnt good for your roof, just something to keep in mind.
Roborana@reddit
The whole house fans vent out through the attic vents. Definitely don't want to just suck the hot air into the attic without venting!

I live in a flat, windy area. If I open windows, an incredible amount of dust and pollen gets into my house. The wind also brings along the scent of manure from nearby farmland and pig barns and the odors from the meat processing plant when the wind blows in the wrong direction. I'll open windows on calm days when it's 50-70 degrees, but those are few and far between.
fbibmacklin@reddit
I keep my AC set to 65 most of the year. My windows are covered in pollen, so I’ll not be opening them ever.
Darth_Lacey@reddit
If the air quality is good, the house gets aired out and cooled down nightly in the summer. I married a snuggle furnace so cooling is important. If the air quality is bad we kinda have to suffer because the portable ac unit only does so much
ghjm@reddit
In my area you'd never even think of leaving your windows open during pollen season, and when that's over it's 90F outside and you want the AC. So leaving your windows open is only really an option in the fall. Most people, like us, just never open them at all, or maybe once a year to air out the house.
farmerthrowaway1923@reddit

My chinchillas can't really take heat over 80, they decide my a/c choices. My main door is open when the weather is above 40 and the high is under 80. I have some windows open at night whenever i can.
Calm-Vacation-5195@reddit
We open windows when weather permits, regardless of the season. It generally has to be between 65 and 80, with relatively low humidity
In the past month or so, we’ve had several three-season days. Cold (around freezing) in the morning, so we have the heat on when we wake up. By late morning, it’s pleasant out, so we turn off the heat and open windows. By 6 or so, the humidity and/or temperature are uncomfortably warm, so we close windows and turn on the AC. Then we turn the heat on at bedtime because it’s getting cold again.
Knitspin@reddit
I love having my windows open. However, the pollen (SC), noise and humidity makes it a challenge. Plus now that I’m older, I like it cold at night. I end up only occasionally opening them.
LeGrandePoobah@reddit
We live in a high desert- windows stay open for fresh air, provide air flow or to cool down. Usually do it when the sun goes down and it’s cooler outside than inside. I suspect we get 8-12 weeks a year that is prime window open time. Other than that, it’s too cold or too hot.
Donald_J_Duck65@reddit
Rarely open the windows. We have heat and central air, so we set a min/max, and it does the work.

Once we start hitting 75 and above, my body physically cannot fall asleep, my asthma gets triggered, and I have to turn the air on.
Standard-Outcome9881@reddit
When the weather is around 70 to 85° or so we’ll have the winds open on a nice breezy day. If it’s very humid, we’ll have the AC on.
HairyDadBear@reddit
I always open my window since I live in a waem climate. AC just depends on the person tolerance. For me it's when it hit 85
Odd-Respond-4267@reddit
I'm on a pnw island, so too cold and wet half the year to even think about it
Summertime closed up, so when ac runs it can lower the humidity.
Shoulder seasons, I use a psychrometric chart to help me decide. If it's close, I don't worry too much.
drsfmd@reddit
Humidity, not temperature, determines when we turn on the AC.
HairyDadBear@reddit
How did you deduce this? I never been in any home that didn't want to open their windows.
shelwood46@reddit
I don't have central air. I have a window AC that I try to wait as long as possible to put in. So my windows get opened when it is over about 68F. We just had a little heatwave where it was in the mid-to-high 80s for a few days and it was so gross and hot in my apartment, but it didn't feel worth it to put the ac in, so I made do with open windows and doors and fans and it super sucked, humid and 85F indoors. It's cool again, thankfully, but I am probably going to put the ac in next month and only open the windows when it dips below 75F until fall. Fresh air is nice, but it comes with pollen and doesn't lower the humidity.
DungenessKrab@reddit
I do the exact same thing you do. If it was a hot day over 85°F. At night i will turn on the fan on my window to let the cool air in.
Lumpy-Artist-6996@reddit
West coast, low humidity, but super hot summers. This time of year, we open all the windows at night and close up in the morning before it gets hot.
During the summer, if the nighttime temp dips below 60, we are fortunate enough to open up and keep the Temps cool enough to just run fans unless the high is mid 90sF or higher.
Winter, I try to open up the house at least once a week, and air out the place. Winters here are pretty mild (lows in the 50sF), so it's refreshing, not miserable.
Happy_Confection90@reddit
I live in the middle of the woods and don't like everything inside covered in thick yellow pine pollen like the poor car gets, so not during the spring. Occasionally during the summer.
jsmoo68@reddit
Yes to opening the windows in spring and fall when the temperature allows.
I close them and put on the air when it’s too hot to sleep in the house. Usually when it gets to above 80 degrees in the house, and the night-time air isn’t cooler than the temperature inside my house.
InvestigatorJaded261@reddit
We always toggle back and forth between AC and open windows, depending on the temp and the humidity. Our house gets kind of stuffy and icky smelling without real fresh air.
hideNseekKatt@reddit
I don't have AC, and I live in a warm/hot region, so I have a whole system on opening and closing the windows to optimize keeping my home as cool as I can. Once the temp inside is at the temp that it is outside and the temp outside will only be going down, is when I open my windows. I then put a box fan or two in the windows and have them blowing the warm inside air out until the temp outside is cooler than that inside and then I reverse the fans to blow the cool air in. I leave all the windows open all night and then in the morning, when the temps start to rise outside, I close up the house and start all over again.
Theslowestmarathoner@reddit
I usually close them before it gets hot outside to preserve cooler inside temps. We usually close up once it gets to maybe 75-77 unless that’s the peak temp. If it’s the peak temp I’ll probably just leave it open
SolOberlindes_2564@reddit
I leave my windows open most of the time, but it never gets above 80F here, and rarely below 60F during the day.
CemeteryDweller7719@reddit
My windows are currently open. Weather is supposed to drop again this week so they’ll be closed again soon, but we are reaching the time of year that they’ll be open 24/7. I don’t have AC, so summer they are always open. Unless there’s a heavy storm and the windows that have rain blowing in get closed. (Most of the first floor is covered by porches so they stay open.)

AggravatingBobcat574@reddit
I like the temp in the house to be around 70 F. I’ll open the windows until the temp gets above that. Then it’s time for the AC.
kaleandbeans@reddit
Any chance we get. We close them if it gets above a certain temperature. Also, when there's fire/smoke nearby.
littletexasbee@reddit
In the fall, when temperatures cool down below 75, and in the spring when temperatures are cool. If humidity is high with moderate temperatures, windows get closed. The fresh air coming through the house lifts my spirits. A lot of people I know who live here never open the windows, and I don’t know why
kritter4life@reddit
Yes we do central coast Ca.
Shadw21@reddit
Yes, regardless if the the weather is nice or not. My apartment needs luften in winter months, other wise it gets warm and humid enough for the mold to grow. When it's summer/autumn and warm enough, I leave the windows open at night for the cooler air and closed during the day to try and keep the worst of the heat out. I really should get a standing AC unit, but I don't have a great spot for it without rearranging my entire studio layout.
BoBoBearDev@reddit

Pittsburgh, Pennsylvania here. We open our windows when we can. Normally we can open them until June, but this year we have had to turn our air on in March
Ruth-Stewart@reddit
As often as possible! Especially now that I own a OLD house and it SMELLS like an old house (I need to do some more wall washing to see if that helps) so I like to air out the house even when it isn’t all that nice outside. But no AC so it’ll have to be done at night pretty soon!
NotABreakfastGuy@reddit
This is based on two things. It's currently nice out, I'd love to have the windows open. I'm also someone with bad pollen allergies and I had to close all the windows when my throat kept swelling.
I will open the windows in the day if it's 70°F or lower. The exception is if it's pollen season and I need to breathe
fairyboyjstar@reddit
I have my windows open right now. I'm capturing the cool air before it gets hot again 😌 I love being able to hear the birds. I don't like being hot and it's hard to control the temperature in my apartment because I have a single wall ac unit so if it's reasonable in the living room it's gross in my bedroom so I close the windows if it's getting hotter inside or if I'm going out and I know it's going to get hot when I'm gone.
kiwispouse@reddit
Our house is 114 years old. I open the windows daily, no matter the season
dobbydisneyfan@reddit
I have mine open right now because I don’t have my acs in but it’s mid 60s.
Easy-Wishbone5413@reddit
I use my attic fan to cool my home as much as possible. When the humidity sets in, I’ll turn on the AC. If a cool spell comes along, I’ll switch back to the attic fan.
Sheliwaili@reddit
Bahahahaha…in Texas, you have to go straight from heater to ac. There might 30mins-1hr of spring air in between
BeanOnAJourney@reddit
Yes because I like fresh air and we don't have air conditioning. I keep them shut on the sunny sides of the house and open on the shady sides.
GardenWitchMom@reddit
If the outside temperature is under 85ish, our windows are open. We do not use the air conditioner unless daytime highs are going to be in the upper '90s. Even then, if the nights are cool we might just close up the windows in the morning and the house will hold temperature until we can open up again in the evening.
Severe_Feedback_2590@reddit

rando_banned@reddit
I have approximately 7-10 days spread out over the entirety of the year where this would be possible. Someone always is burning something stinking up the entire area when those days are here.
Grouchy-Macaron-1780@reddit
My windows never open. I use the central AC/Heat from the central HVAC unit. Most modern homes in the US have central AC with forced air. Many in the UK/Europe have a split system with a blower mounted to a wall. Until you experience Central AC, nothing else compares.
Pollen, bugs, and humidity are constant issues. As is heat, with humidity.
I have a home also in Greece where the Ac is a split unit/ Wall mount. It really does almost nothing except for the room it is in. It doens't remove humidity as well as a central HVAC, forced air system. and I suspect the plaster walls, built over a concrete/stucco type of outer wall has no insulation in it. The effect is that the AC just can't keep up. As soon as it shuts off, you can feel the warm, humid air moving back in.
Timely-Belt8905@reddit
I wish I could open the windows in my home, but I can't anymore because of the stench of pot smoke everywhere now.
vacuum_tubes@reddit
Yes. In NorCal it's mid 80's daytime and mid 50's night time with low humidity. Cool the house down at night with windows open and AC is not needed much.
Abject_Stand_4348@reddit

dararie@reddit
I refuse to use my AC before May 15th, so I open the windows until then. Of course when it’s over 90 like it was this week, I don’t do much, just sit and read
HorrorAlarming1163@reddit
Too much pollen and too many skeeters for that
SRQmoviemaker@reddit
Yeah but that nice weather is only here a week or two between summer and winter (& vice versa). Basically im AC all year until the high temps stay in the low 70s. Then once it gets warmer than 76 in my house the ac goes back on.
Khpatton@reddit
Never. I have awful seasonal allergies and live in the Deep South. Even if I didn’t have allergies, the spring Pollening would everything I own chartreuse. I also have cats who will tear right through a screen, so I probably wouldn’t do it anyway.
What my wife and I do instead, when we need to freshen up the house or get air moving without running the AC, is use our attic fan. We live in a house that predates AC, so that thing is powerful. It suck out all the hot air in the spring and summer and vents it out through the attic.
Odd-Tell-5702@reddit
Not usually. We have a screened in porch so we usually open the back door and stay out there.
Secure-Ad9780@reddit
My windows are open every day unless it's extremely cold and windy or very hot and humid. I close them in the late afternoon in winter. I pull the shades down over sunny windows, leave the shady side wide open. I like fresh air. I had my heat on for 5 days in Mar. I rarely use my central air, only my bedroom window AC for sleeping when hot/humid.
maddmax_gt@reddit
Sometimes. I don’t trust my cats or my screens all that much though lol
HKGPhooey@reddit
No. Usually when it’s cool enough to have the windows open in the spring and late fall, the pollen count is really high. People in my household can’t handle that with the allergies they have. So we have the aircon on. Aircon filters that shit out. So, unfortunately I can’t have the windows open.
SailAwayToTheMoon@reddit
Californian here. Open as much as possible. All day then cracked at night (even in winter). Hell, I’d tear down the walls if I could. My ideal space would be a covered patio or a giant gazebo filled with home furniture. Cover it with a bug screen and I’d never leave.
dinamet7@reddit
I have fantasies of tearing out the walls on the back side of my house and just having a floor to ceiling walls of windows/glass doors (with screens) so that I can sit there and zone out while staring at the plants or the sky or the birds and lizards. I wouldn't need a TV.
SailAwayToTheMoon@reddit

We don’t close our windows until it gets to “surface of the sun hot” in the summer. But we’re in Los Angeles so it’s not like we have seasons like winter.
ipsedixie@reddit
South central Arizona here. At this time of the year, we're opening the windows for a few hours in the mornings. Most days my husband and I are up before 4 am (because I start work at 4 am), and we'll leave the windows open until about 8 or 9 am. We had some weeks in March where it got over 100 and the windows stayed tightly shut. And we're coming up on hotter days, where, again, windows will be shut for months because the low will be in the high 80s F. My parents and one of my siblings lived in this house before us, and they never opened the windows as much as we do. But we have cats and our cats want to watch the birds in the yard. It's going to be hard for them when we shut the windows for about 4 months. It's really nice in the morning to have the windows open and catch a breeze going through.
msmicroracer@reddit
Just closed mine last night after the cold front came through. I’ll keep windows open until temperatures reach 85 in the house hopefully first day of summer but I don’t think that’s going to work this year

gregrph@reddit
I'm in South Florida so for 10 months of the year it is either too hot and/or too humid. On e the temperature gets below 70 degrees. F. the humidity usually drops and I will open the windows and sliding doors. If there is even a breeze or outright wind it is even better. I love not running the air conditioner! We RARELY turn the heat on. Maybe once or twice a year for a few minutes to take the chill out of the air a bit in the morning.
thirdeyefish@reddit
I prefer the fresh air when I can get it. I don't run air until it is going to be too warm, or it it is really noisy or there is some air pollutants like a smoking neighbor.

Ok-Dealer4350@reddit
Many people have allergies and leave things closed. I open an occasional window.
Lately it has been in the 90s when it should be in the 60s. The transmitter for my furnace/ac crapped out. I could not turn off the heat. I bought a new thermostat about a month ago since it had a better tho not great review with the idea that the connection with HA would be better.
When the ac disappeared, I called the company I bought both furnace and ac from, asked them to install the new thermostat and find out why the ac didn’t communicate with the ac. I managed to keep the house at 82 w/o ac, but slept poorly at night due to the shift to higher temperatures. I had to explain to hubby that flannel pajamas were not conducive to sleeping at 80 degrees and that one hear lots of traffic noises with the open window. Better to close it to prevent us from sneezing.
It took 1.5 hours to figure out what was wrong, grumble about the thermostat that I did not buy from the dealer and fix the problem.
If I lived near the coast in California, I’d have my windows open - low humidity, sea breezes, lovely weather. Here I have humidity and heat. I normally keep the house at 78. After a number of hot dates, I set the thermostat at 76.
myshellly@reddit
I don’t understand the whole “turn on the air conditioning for the summer” thing. Turning on the AC is a button. If I want light I press this button, if I’m hot I press that button. It’s not a big seasonal decision like opening an outdoor pool. We use our AC pretty much 24/7/365. We don’t turn it off if I open a window.
I think of windows as smell control, not temperature control.
cocuke@reddit
Given my options I don't turn on the ac. My wife has different ideas. She has always worked inside and has become accustomed to climate control. I grew up on a farm, worked construction and just generally spent my time outside. I have lived in areas where the heat and humidity were excessive and always tried to acclimate. When my wife is not around in the summer the ac gets turned off. I don't mind coming in and the temperature inside being in the 90s. Most of the world has to deal with what is around them. Open windows in the summer is all I want or need.
Catrina_woman@reddit

Windows are open when it hits maybe like 60-74 or so. If it gets hotter than that it’s almost time for the AC.
KaetzenOrkester@reddit
Yes, I open the windows when it's nice outside. My general rule is I close them when the outside temps approach when I would cool the house to. I'm lucky that I live near a river delta and the delta breezes help cool things off when it gets hot.
That said, I also have allergies, so I use apps to see what's in bloom and I don't open windows when my allergens are in the air.
Slow_Concern_672@reddit
If it's still cool at night I open the windows at night and close them.in the morning and shut the blinds to keep the cool air in and hot sun out so it might look to you that I never open the windows but I do. My house however is chalet a frame and it gets hot as hades in the third floor even if it's 80 outside and 70 on the first floor the top floor will quickly get to 95/100.
Zephyr_Dragon49@reddit
I do. All my hot stuff is gas and there's quite a few pets in here. Gotta let all that co2 go somewhere else.

We don't have air conditioning (Southern California, coastal-ish, grew up in the area and never had AC.) I open all the windows in the morning and close them before bed or if we are leaving the house. In the summer when there are heat waves, all the windows are closed, blackout curtains stay shut, and then everything opens up in the evening to let in the cool night air. Lots of ceiling fans for those days where the breeze isn't breezing, but otherwise we always have a nice coastal cross breeze running through the house.
No_Refrigerator_4990@reddit
Yes. I live in an area with pretty mild weather, so we can have our windows open for a good portion of the year. Even if it’s a colder day or decently hot, I try to open the windows for 20 minutes or so to air out the house in the morning. Also, we don’t have lots of mosquitoes or other bugs here. The biggest reason I keep the windows closed is when it’s really windy and I’m trying to keep the pollen and dust out.
goblin_hipster@reddit
I'm pretty sensitive to smells, and I also like the cold, so I prefer fresh air. My window stays open between about 40⁰ to about 80⁰.

They’re open now, because it’s 55 outside and the sun makes it 80 inside. I’ll switch to AC cooling when I want the inside to be under 75. That’s usually jun-Sep when I get home from work, or if the outside temp will be above 80, so the cat stays cool
Hamblin113@reddit
Don’t have air conditioning and live in Arizona. Did put up a blind to keep the west sun from coming in. Need to go outside in evening as it is cooler. Have an attic fan but nit sure the benefit. Some in the area leave windows open at night and close during the day, to keep the cool in.
If houses were designed properly, similar to Acoma Pueblo, openings would be only south so summer sun is in the North keeping heat out.
Esmer_Tina@reddit
My screen windows are not reliable enough to keep windows open without insects getting everywhere. And when it’s nice enough to have windows open, the pollen is intolerable. So if I had better windows and lived in a different climate, I would.

At least one partially open window 100% of the time. But live in San Francisco so it's 55-75° F (12-24 C) 90% of the year. Most here don't have AC but heat is common.
FoggyGoodwin@reddit
Windows as soon as it's warm. We had a heat spell earlier this year, I opened several windows. It got cool, closed all but one. Got chilly, closed the last one. As it warms, I'll open them back up. Eventually I'll add fans and maybe those damp evaporative cloths.

I think it helps that the average Houston resident isn't walking for miles in the heat every day, or spending time in 110-year old subway stations that turn into blast furnaces when it's hot out
ScrimshawPie@reddit
As someone who spent a lot of time in Houston and NYC, agree. NYC is RIGHT on the water, and can get very humid. Even Houston levels. Plus walking in the hot, stinky, streets and subways... AND many old buildings don't have a/c anyway... it can be more uncomfortable for sure.
poortomato@reddit
Yes! And not to mention, NYC and surrounding areas, like Long Island, are now classified as humid subtropical climate, just like Florida and Texas. But without the AC infrastructure to support 😭
My parents on LI have a window unit in every room and fans going all day in the summer. They were quoted $60k to retrofit their house with central air so they passed on that.
I was up in the area last year, specifically in the Bronx on July 30, 2025. It was a high of 95 that day, with a high of 97 the day prior. Standing outside in direct sunlight with all the heat, humidity, and no breeze 😫 thankfully, it rained after a couple hours and that helped cool things down, but it was very reminiscent of Texas heat, which I was hoping to get a break from 😅
PopEnvironmental1335@reddit
I’m from the gulf coast so yes it’s definitely hotter down there than NYC, but most apartments here don’t have central air and you’re outside walking in the heat. Back home, I’d go from air conditioned house to car to indoor destination. It’s easier to stay cool down there. My neighborhood in NYC also has a few blackouts every summer because the electrical grid wasn’t designed to handle all the window AC units. If you visit, you might find that it feels hotter than you’re expecting even if the actual temp is lower than FL.
Traditional_Way1052@reddit
Usually its in the 70s or 80s. Consistent temps in the 90s is rare. You're more likely to get a day here or there. August is warmer than July. Try July, if you can.

Near Charlotte NC. I open them when it is warm enough. I love the fresh air. Pollen has mostly fallen and passed. I put fans in the windows to circulate the air. Usually late June seems to be the time I have to turn on the AC—when it stays over 83 at night. I prefer it warmer. I think a lot of people are just accustomed to low AC temperatures. Meanwhile in spring I walk into stores and think “why is it so cold in here?

AnswerAggravating646@reddit
Kind of backwards bc I live in Florida. But I try to open them around Thanksgiving-Christmas and I like to leave them open until about now. Once in a while, I still gotta go with the AC in winter time tho. I’ll need the heat on in the winter less frequently than the AC
BurritoBowlw_guac@reddit
100% my husband always wants to shut up the house and turn the A/C on before I’m ready. Love having the house open. Rural Midwest here
kanakamaoli@reddit
I'm in the tropics and dont have ac, so the windows are open 90% of the time. 50% of the time, fans are blowing as well.
Several_Ad_6576@reddit
If ball_sweat == TRUE then AC_ON = TRUE Windows_open = FALSE Else Windows_open = TRUE
A little pseudo code. Would need to add in logic for when my nips are freezing to decide on heat.
Welder_Subject@reddit
It’s super hot and humid here so I only open the window in the morning
VeronicaOnTheMoon@reddit
Cat in the spring because of the pollen storm. Can in the summer or autumn because of the super high humidity.
RektInTheHed@reddit
With the price of energy being this high, I absolutely keep the windows open until it's unbearable. Which is sustained 90's.
spintool1995@reddit
I'm in southern California, our windows are open mostly 24 hours per day for about 8 months a year. We close them from evening to mid morning in the winter and occasionally turn on the heat, and close them from about 11am to 5pm on summer days and turn on the AC when it's going to get up to 90 or higher.
El_Polio_Loco@reddit
No. The pollen is too prevalent for windows open. I accept that I’m just going right to AC when the house gets too warm.
tiggipi@reddit
We usually keep ours open in nonrainy weather between low 50s and high 70s Fahrenheit. Otherwise we'd be uncomfy.
Aggravating_Isopod19@reddit
I do. I only run my a/c if it gets too hot inside, which, fortunately for me isn’t many days a year.
gard3nwitch@reddit
Sure. When it's neither cold not hot.
Phoenix_Court@reddit
The period of time where it's not too hot to do that is fairly small where I live. I also don't love having windows open just as a safety thing.
I do open them occasionally, but it's pretty rare.
Brilliant_Mix_6051@reddit
We have warm and dry rather than hot and humid summers where I live, so we leave windows open a lot. That’s not the case for most of the US.
gunterrae@reddit
We do open them, but living in Michigan, eventually the humidity is too high to be comfortable even if it isn't super hot, so the A/C comes on and the windows get shut.
ReadingRainbowie@reddit
I leave em open until i start sweating lol.
tcspears@reddit
I grew up in Boston without air conditioning, so we open our windows in the late spring and close them in the late fall. Air conditioning is more prevalent in New England now, but many of us grew up without it, so it’s seen as a luxury more than a given.
Moist-Pea-8034@reddit
I love having my windows open but like others with all the pollen and humidity where I live I only have a short window in the fall and spring. Looks like it’s already over for this year too 👎
DizzyFly9339@reddit
In an ideal world, I would absolutely rather have the windows open when it’s nice out. But my kid has very severe tree pollen allergies so we have to use HEPA filters in the spring and keep the windows closed.
In summer it’s too hot. Where I live, power outages in the summer can be pretty dangerous. You have to use air conditioning, not just for comfort, but for safety.
We do usually have the windows open in the fall and on warmer winter days. If it’s above freezing outside, we probably have the windows at least cracked for airflow.
DesignByChance@reddit
Windows open as much as possible. AC comes on when I can’t stand the heat anymore.
Obtuse-Angel@reddit
I open the windows when it’s nice, when it’s a little colder than nice, and when it’s warmer than nice. I don’t keep the windows closed with the AC on until the days are consistently higher than 88°f (31°c).
Sparkle_Rott@reddit
In Spring and Fall all of the windows are open. If it gets to the mid 80s F inside or if the humidity goes up, AC it is.
Also, windows open at night in Winter. My mother grew up in a German household lol
Crochet_Corgi@reddit
Yes, for that brief time, it's not too cold, or hot, or rainy, or super windy, or too pollen filled, or smokey.
Ok-Equivalent8260@reddit
I’m in Seattle, so I never turn on the air and leave the windows open all summer
Common-Parsnip-9682@reddit
We don’t have AC. In the summer we open the windows to cool the house down, and close them again in the morning to keep out the heat.
MiddlePop4953@reddit
Yes. I don't have air conditioning, so when it gets hot I open the windows at night while it's cool, then close them during the day and shut the curtains. Keeps the house relatively cool without air conditioning.
urfriendflicka@reddit
I love opening the windows and letting fresh air in, but I am essentially allergic to the entirety of the outdoors every season but winter. I do risk it occasionally, but never on the days when I look out the window and can see the coating of pollen everywhere. I usually wait for a good rainy day...I'll wait a few hours so the pollen has been good and washed away and really love an open window during an absolute downpour.
Speedoflife81@reddit
Yes no AC so use windows to cool house
DueLeague4668@reddit
I don’t have an AC😭
WhompTrucker@reddit
Yes. I'm heat intolerant so anything below 70 I'll open up everything. Above 70+ outside I turn on the AC
woodwerker76@reddit
We open the windows at night and close them when outside temperature is warmer than inside temp
c4ctus@reddit
I turn on air conditioning for the summer usually in mid-February.
Cheap_Coffee@reddit
I do open the windows. I put A/C units in the windows when it gets "too hot." "Too hot" is varying measure.
MaddyKet@reddit
For me, it usually becomes “too humid” first. I open the windows sometimes at night or when it rains. Can’t have it open all the time because the pollen is bad.
ElefanteAmor@reddit
Always. Until it gets warm and the trap the cool air in
Jay_Lockhart@reddit
I do. AC is too expensive, I only ever turn it on for a few hours at a time and usually only if it’s so hot and humid inside I can’t sleep even with no covers on the bed.
NotACrazyCatLadyx2@reddit
Windows and doors open until A/C kicks on (at 79 degrees) when I run through the house closing them. I will do that until the night time low does get below 75. Then it will be all A/C, all the time. I use the heater maybe 5 - 10 days a year.
wwJones@reddit
Every window in my house is cracked open.
KrispyAvocado@reddit
I open in the morning when it's cool asked close when it's warming up (with blinds closed) asked UPenn again after it cools down in the evening. No ac here. I love fresh air and prefer it to ac unless it's super hot. I've never lived with ac though. I go to the store or somewhere else with ac when it gets brutal
Kalypsokel@reddit
If it’s not gonna get above 50-55 degrees I’ll open my windows. Anything above that and no way. My AC tends to run all year round even if it’s only for a little bit to bring the temp down for sleeping. Humidity is what kills me. I’m in Northern VA and it’s warm about 9-10 months out of the year now. This past week it was mid 90’s. My comfort is important. I’ve lived without AC before and I refuse to do that now. I don’t tolerate the heat well in my older age lol. I blame those years without AC for that.
bazilbt@reddit
I do open my windows, as I'm able.
Bananapopcicle@reddit
In Georgia there are 15 whole days in the Springtime when you can open your windows when it’s a) not swelteringly hot and b) yellow dusty pollen
NickCharlesYT@reddit
No, because it's basically never "nice" it's either hot, humid, or both 99% of the year. The remaining 1% is dry season and my allergies would be 10x worse if I let all that pollen and dust in the house.
Rattlingplates@reddit
Don’t have ac in my town so yeah windows opens
LawPirate@reddit
I can’t remember the last time I opened a window. We might do it for a couple of hours a year, if it’s nice out and we want to let some fresh air in. We just set the thermostat to auto with the heat around 68-69 and the A/C around 73-74 (depending on the time of day). The house is always between those temperatures.
Traveller7142@reddit
I close my windows when it’s uncomfortably hot. I don’t have AC, so I just close the blinds and curtains
Bitter-Reindeer1774@reddit
If its 75+ and no breeze the A/C is on. I love having the windows open and getting fresh air blown through the house so I try to push it until my wife and I become uncomfortable.
B3gg4r@reddit
In the desert, there are maybe 3-4 weeks out of the year when the weather is nice enough to bring inside with us. Winter is far too cold and winds are far too high. Summer is scorching. But during those two weeks in spring and two weeks in fall, the windows are open all the time.
frightful_zoo28@reddit
I desperately WANT to air things out and enjoy a fresh breeze, but unfortunately pollen and humidity are hell for those of us with asthma and allergies, even when it seems mild and refreshing to others.
ToastetteEgg@reddit
In winter if it’s warmer outside than in I open them. In summer I keep them open upstairs to blow the hot air out and close them when the air outside starts heating up. I rarely use my A/C.
Kanya_Mkavry@reddit
I live in Phoenix Arizona. I would keep the windows open all winter, as the weather is so mild. My husband can't deal with anything below about 50, so we usually just have them open in the spring and fall.
Rojo37x@reddit
I'm happy to have them open generally anywhere between 60 and 80 degrees. Assuming it isn't storming. In some cases low to mid 80s is still ok to keep them open if there is a decent breeze and I have my fans going. But mid 80s is definitely too warm for it to be comfortable for my family. Of course in the Midwest, we can go from no AC, to AC on, to AC off, to heat on all within 24 hours.
shammy_dammy@reddit
Key phrase 'when the weather is nice'. And the answer is yes, until the weather isn't 'nice' anymore.
Sergio_Poduno@reddit

Similar_Corner8081@reddit
No the pollen is so thick you can cut it with a knife
Coloradozonian@reddit
I love to do this now that I’m an hour outside of phoenix and it’s not so bad. In phoenix I literally could only do this November to maybe end of feb. Now I do it up here near Prescott from mid feb to July😇 this year has been weird . It was more like end of dec to now but probably will go to first week of June if we keep having amazing weather🥰We’ve barely had any snow and not many cold days. I don’t have central ac as I bought a 1907 home and I love cold anyways so if my windows are open and it’s bright I’m a happy bitch
Mind_Melting_Slowly@reddit
My family has horrible allergies to tree and grass pollens, and I don't like it when it gets over 72°F outside. So our windows are almost always closed (pollen is a 3-season event) and the A/C runs 8-9 months of the year.
Glum-Welder1704@reddit
Basically, if it's nicer outside than inside, I open everything. In summer, that means open all night, and in the morning until it gets warm or I'm leaving the house.
xx-rapunzel-xx@reddit
i’d be nice! but we don’t.
just this past week we had above-average temps which made me happy for the first time in a while but we didn’t use the AC. we use it in the summer mostly.
auburncub@reddit
I would love to but my windows don't have screens and my cats would take the opportunity to make their great escape
Itzagoodthing@reddit
Yes, until low to mid 80s, depending on humidity.
HidingInTrees2245@reddit
My windows are open by default. I only close them when it’s too cold or really hot. I use fans and strategic closing and opening of curtains and keep it pretty cool that way even when it’s around 80. More than that and the AC is getting turned on.
Kmdvm@reddit
When it's nice yes. We do need to replace a bunch of screens to prevent bugs as we get a bunch of mosquitoes, but I like the fresh air as much as possible. When it starts to get to mid to upper 70s (F)/24+ (C) that's when I usually close them bc we don't get the best circulation in our house
Dragonfly2919@reddit
All the time but only the back windows, rarely use the front windows
rando439@reddit
San Antonio, TX here. If it's cold out and raining a little, I might crack them a bit. If it's nice out, there's a 99% chance that the pollen blowing in will cause massive discomfort to those living in my house. AC comes on when the heat/humidity combo hits the point where it is impossible to sweep the floor or wash dishes without heavy sweating or when it's over 82 F inside the house if it's not humid.
Unless the windows are open, the fan is set to run a couple of times each hour to keep the air from getting too stagnant, too.
Spyderbeast@reddit
I leave my back door open as much of the time to give my dogs free access to my fenced backyard
I'm okay if I keep my indoor temps between 50 and 80 degrees. My energy bills are less expensive when I focus on my immediate area, and use ceiling fans in the summer, and electric blankets in the winter
It's probably a good thing I live alone, because not everyone is going to tolerate that range, but I love that my combined electricity and natural gas bills rarely exceed $100/month (on a four bedroom house)
AppointmentRough7822@reddit
Here in SoCal I leave them open most of winter and spring. Summer it stays closed and AC stays on
ReeMayRe@reddit
If it's hot or cold out, I just crack them for a short time to get fresh air in the house. Otherwise, I leave them open
uhhhhh_iforgotit@reddit
My windows are open all day once it's above 65. Up until summer then it's open all night to cool the house then close the windows, thryv stay closed until the outside is the same temperature as the inside then they open again.
Otherwise all day and night unless it's raining. But I don't have to worry about people breaking in where I am
Persis-@reddit
Upper Midwest here. I had my windows open all night last night. Closed now because the temperature is dropping.
Windows are open when the humidity isn’t too high, the pollen isn’t awful, and the temperature is comfortable. In less than a month, my white pines will bloom, sending green clouds of doom all over my yard. The windows are closed for that.
BlackBartKuma@reddit
We open ours when it's nice, usually early spring and late fall in Arizona. If the AC starts kicking on when the windows are open, that means hits too hot and we need to close
luckymountain@reddit
I’m in Phoenix area of Arizona and after reaching the 100s earlier this month, we’ve had a couple of weeks of 60s at night and 80s during the day. I open my windows in the evening when it cools off to the mid 70s and close them in the late morning when it starts warming up. My house stays cool all day with no need for A/C. I’ll continue to do this until it stops cooling off below mid 70s. Then it’s A/c when needed. By summer(June ) it will only cool off to the (eventually upper) 90s all night and then I’ll wait and wait for November to open them again 😊
ConcertinaTerpsichor@reddit
Pollen and humidity and insects like mosquitoes are major factors in deciding when to open and close windows. We have so many different climates here. Usually in the Southwest and California, open windows are fine, but in the south east states like Tennessee, Alabama, North Carolina, you do NOT want open windows except very early in the morning.
gettingsbriana@reddit
Iowa here, I do. Put a box fan with one bringing air in and one pushing air out and it will help cool the house easier. Bonus points if you leave them on overnight on low 😊
Particular_Bet_5466@reddit
Here in Colorado at night yeah it’s always cool
Commercial-Catch-615@reddit
No. I made the mistake of picking a beautiful spot to build my house overlooking a 5 acre tank on our ranch. The bugs make it impossible to ever open a window. I can hardly open the doors part of the year.
YoshiandAims@reddit
Yes. I air out my apartment often. Most days I open the windows and set up my fan.
I turn on the AC when the temps become deeply uncomfortable or dangerous for my dog, and myself.
I use AC exclusively at night once it hits 80-90 degrees Fahrenheit, as my windows are ground level a little more than 5ft tall. Open by the side (like a door) It makes it easy for a break in by humans and animals. They get closed and locked all night.
I'd be happy for an open window and a fan at night some of the year, but, it's just not a great idea, safety wise.
ancientastronaut2@reddit
Yes, as much as possible. I love fresh air and a breeze coming in.
It makes me happy and relaxed. And I can hear the birds.
During winter or extreme heat in summer, it feels so stifling and claustrophobic.
entropynchaos@reddit
Definitely not into the upper 80s! We open the windows into the mid seventies maybe but I hate heat.

LordLaz1985@reddit
Here in Florida, it’s only in the 60s/70s when it’s raining. So no, we have our windows shut.
It also helps keep the lizards and the mosquitos out.

Windows and doors are open when temperatures outside are 57ish to 85
k0uch@reddit
Yes. I open the kitchen window and front door, then I open the the back door. In the mornings I’ll put a fan to pull air into the kitchen hen and push it out the back door, as the sun moves I’ll switch the fan to the back to push air from the back door to the front
Muvseevum@reddit
Yes! We have a whole-house fan that pulls air through, well, the whole house. It’s awesome in spring and fall and even some summer nights.

Yes... Have had windows open a lot in Feb/Mar. (Kansas)
Feb through April can be anything from 90F to snow so we might have a week where we have a day of using the furnace, a couple days of open windows, some A/C and then furnace again.
Just Kansas things ...
Otney@reddit

We do not have them open unless something out of the ordinary happens like a kitchen fire and we're trying to get rid of the smoke and its smell.

Dawk1920@reddit
Our last house was built in 1959. We had some additional insulation put in the attic and spray foamed to seal any cracks on the attic and crawlspace. I even insulated the crawlspace too. The rest of the house you could tell wasn’t insulated very well.
When it was cold outside it would feel colder inside and you had to crank the furnace up. That being said, one time my wife and I woke up a little past midnight and oh man didn’t it stink like skunk even though all the windows and doors were closed!! At first we couldn’t figure out if one of our neighbors was just smoking some really potent weed or if it was a skunk lol.
amkdragonfly2513@reddit
Omg. It's become a new game here. Is it weed or a skunk. I feel skunks have more of a burnt rubber smell.

sacrelicio@reddit
I live in Minneapolis and spring and fall can be very variable. So a really nice day? They're open. But then it might get cold for a few days so they stay closed. Then if it starts getting into summery weather the AC might come on. If anything it's the sun angle that makes my house too hot, especially upstairs where we sleep. But a lot of older houses don't have AC so they just use windows all summer.

A/C costs a lot of money. My brother and I have a competition every year of who can go longer without turning on the A/C or the heat, depending on the season. He always wins the A/C competition, because he lives alone and can just keep taling off clithes until he is down to a pair of shorts. I live with my adult son and have to be more modest! 😅

I prefer to have my windows open as much as possible, but when the inside temps reach 78f, I close them and turn on air conditioning.

Later in the evening, as soon as the outside temps drop below 76, we turn off AC and open all the windows again.

I love to have fresh air in the home. I open the window in the bedrooms in the evening and morning for 30 min. My sliding door stays open as much as possible. I do that in the winter, and early spring and whenever we have no pollen, extreme humidity or heat. The weather in NJ can be really hot and humid and this prevents me from doing it every day.

My part of the state is too humid even in relatively nice weather to keep the windows open much, unfortunately. In fact, it tends to be most humid on those nicer days, as the bay‘s moderating effect on temps brings humidity.

My part of California has great weather, so i have open doors/windows most days April - October. In the summer I open door/windows in the evening and close them up in the morning when it starts to heat up outside. The house stays cool and I only have to run the AC about 2 weeks a year.
dasHeftinn@reddit
I sleep right next to a window; at 3 AM I stirred awake and heard that it was raining, so I opened my window, I like the sound of rain and my cat likes to sit on the windowsill and look out. It has been ~90 degrees the past few days, it’s 53 degrees now, so my AC isn’t constantly on, there’s a cool breeze coming through, and I’m still in bed listening to everything outside. Honestly, the perfect lazy Saturday that I wanted.
Dry-One4182@reddit
All depends on temp and humidity. AC is set at 73°F. Outside between 69°-73°F with RH below 50% windows are open.
_Johnny_Fappleseed@reddit
I think the general consensus about the American experience - even though this place is massive with several different climate regions - is that everyone uses air conditioning generally, but obviously a century ago that wasn't a thing. Our houses are built different now and in some places it would likely genuinely be dangerous to not have the option (I'm thinking further south) but it really is still possible to live without it overall. It would be a different story if someone had severe health problems that could make it dangerous.
Where I live the climate is becoming humid subtropical because of climate change but we personally don't have air conditioning, even in almost 100F weather (almost 38C). We leave all the windows and doors open (and have screens because the insects here are awful) and might pull the curtains during the heat of the day if it's quite sunny. We always have fans to keep it cool or dry and for drying the laundry if we can't put it outside. If we lose power from storms we just use hand fans or use a little water to cool (which has a limit - if it's too humid water on the skin doesn't matter since nothing evaporates quickly).
You just get acclimated to it and, like other regions where it's terribly hot, you just try and do less during the heat of the day if possible. Besides, air conditioners give me a headache. Honestly we prefer it this way now.
ccroy2001@reddit
Wow this is interesting. I live in Southern California so it's not too humid. There is some pollen but not a crazy amount. I live upstairs so my windows are open most days. If it's late summer and very hot I'll close them and use AC, but still open up the house in morning before I go to work.
elveebee22@reddit
In Southern Arizona it's the opposite lol, I let fresh air in all day every day from like October to April, unless there's a heat wave.
MsPennyP@reddit
Depends on various factors. When I lived in NC. There was 2 days a year I could open my windows. Either pollen, rain, heat/humidity kept me from it.
Now I live in Colorado I have lots more days where I can open them. But days where there's too much smoke from wildfires, a few days of too much pollen (tons less than NC though), keep them shut.
Usually turn ac on when temperature gets to be ~ 70° so there are days I'll open them in the morning, close them midday, might reopen in the evening, and use AC during the hot part of the day. There's days I'll use heat-windows-ac-windows-heat.
NPHighview@reddit
It's not a matter of "open them in the spring, close them in the fall".
We open and close windows throughout the day to account for internal vs. external temperatures, time of day, etc. Our default summer routine runs something like this:
7am - close all the windows in the house. Close the blinds on the south-facing windows. Temps rise to 85-90°F (\~30°C) during the day, with unobstructed sunshine here in southern California.
11pm - open windows around the house and turn the whole house fan on for an hour. Open the shutters in the bedroom, and turn on the ceiling fan, low. Temps drop to 55°F (\~13°C) during the night.
We can go for almost the entire year without A/C using this routine. But we've already had a two-week stretch of 90°F days in March, roughly 30° above normal for this time of year.

So going from winter to spring from where I grew up I would open windows once it was 40/5 (Fahrenheit/Celsius) to about 85/30. Probably once mid 70s I have to have fans on. Anything above that windows and blinds closed with air conditioners are absolutely on, but I also don’t have central heating and this way I dump have to dump them as often. I don’t like a like a cold house if I am working outside all day in the heat.
When I was in Baltimore for 3 years, I had to turn my fans on high before leaving with aircon on so my bedroom wouldn’t be hotter than 95/35 when it was over 100/38 outside. I would turn the fan on low or med if I was in the room.
My grandparents didn’t have air conditioners so that was just you had to deal with the heat and I am moving to an area where the average high in the summer is below 70/21.
Peeeeeps@reddit
I open my windows in the Spring and Fall as much as I can, but in Illinois there's often not many times you can keep your windows open unless you have a highly shaded house since you still deal with the humidity. If the humidity was half what it is I could probably keep my windows open longer, but 75+ with high humidity things start getting sticky quickly and it's just not enjoyable. Fans don't do anything for humidity.
Dizzy_Description812@reddit
Unusually when the low is above 60 and below 75 I keep them open at night. During the day, it depends on the humidity. Where I am we get occasional 100 degree days and very humid.
Flimsy_Equal8841@reddit
No, I live near a busy street. Between the noise and the pavement dust, it would be a horrible experience.
Oomlotte99@reddit
I open my windows until it is too hot or cold to do so.
anneofgraygardens@reddit
I don't have AC. I keep my bedroom window open almost every day.
Pemminpro@reddit
Yes for the 2 weeks a year when it isn't during frozen tundra, swamp ass humid, or tree orgy season.
Common_Cut_1491@reddit
Miami, here. I try to keep my windows open as much as possible. Most of the older homes built before 1960 or so were built to maximize air flow and with naturally cooling materials. We do okay with the windows open from late fall to early spring. That said, on especially humid or rainy winter days, we close them. That, and winters have been getting warmer.
ImCrossingYouInStyle@reddit
Absolutely! Conditioned air (A/C) is fine, but I prefer what nature gives me when it's tolerable. So up go the windows when it's a reasonable temp, not too humid, and not pouring rain or snowing.
Background-Cod-7035@reddit
Absolutely! But rule of thumb for us is that if it’s hotter outside than inside close the windows. Our house is stone and stucco so retains a moderate temperature really well. There’s a lot of opening and closing of windows in mornings and evenings.
im-not-a-panda@reddit
We open windows when it’s around 68-75 outside. AC kicks on at 75 and heat kicks on when below 68.
hokiegirl759397@reddit
I never open the windows in my apartment. Definitely don't want any bugs getting inside. I'll turn my air conditioning on when it's in the low 80's outside. It's been extremely hot and humid in Virginia for the last week. I'm looking forward to cooler temperatures this week.
farawyn86@reddit
The only time I close my windows is if it's torrentially downpouring, which is like once a year. San Diego.
RodneyBarringtonIII@reddit
We open our Windows when it's between about 60° and 80°, unless there's an air quality alert. The alerts are becoming increasingly common, though.
Ti_Cocodrie@reddit
In Montana I frequently turn my AC off and open a window.
In Louisiana, it was essentially never because the humidity is high enough to drown in.
SlyHutchinson@reddit
Windows are open everyday in spring and fall. Currently open now and have been for the last few weeks. In summer we do it til the temp outside gets into the 80s and then close up til the evening when it goes back down. Yay California.
poetic_justice987@reddit
Windows open until it’s about 90F outside.
losthiker68@reddit
We're in Texas so the seasons that allow open windows is short. But we live on a lake with lots of native plants in our yard. We can usually get a nice breeze through the house if we open windows on the lake side and the opposite and it brings those lovely scents through. We have jasmine growing near the front door so right now the whole house smells of it and it is wonderful.
Fit-Building-2560@reddit
We do if we live in a region that's not too warm. I don't see much point in opening windows just to let 80-degree temps into the house. The strategy in coastal locations in the West is to open the windows in the morning when it's cool, then close them to conserve the cool air inside the house for as long as possible. By evening, when the temps go back down, you can open the windows if needed. Using awnings to shade large windows and glass doors on warm days also helps keep the house cool.
Most of the coastal areas in the western states didn't need A/C, so it didn't exist in homes or businesses. That's been changing in the last 20 years or so.
mckenzie_keith@reddit
Where I live now is similar. Except I don't have air conditioning. So I open the windows in the spring some time and then they usually stay open until fall.
This varies widely across America.
krill482@reddit
I open them in early spring as well. They stay open until the end of May. June through mid August it's too hot and humid so they stay closed. Then open them back up from August til mid October.
lilfoothillsheaven@reddit
Yeah... But I'll be honest we are more likely to just leave the doors open. Still a little chilly to have anything open for very long, I don't like my house to drop below 60F/ 16C Montana
trikakeep@reddit
Every nice day over 50° I have one or more windows open. I only have a window ac that runs when the humidity and temps are oppressive in summer
ChapterOk4000@reddit
San Diego, California here. We used to have our windows open year round, most all the time. About 15 years ago we had ac installed, because late summer started getting humid (odd for a coastal desert), and running that afternoon to remove the humidity, and still open windows at night when things cooled off.amy homes here were built without air conditioning, or even heat.
Fast forward to 2020s, we're running the ac for 5 or 6 months of the year, especially September through end of October when temperatures get up into the 90s with humidity, which again is very odd for our area historically.
Justadropinthesea@reddit
My windows are open every night year round and whenever the weather is in the 60s- 70s during the day. I live in a temperate climate and my body is not adapted to temperatures over about 75.

ophaus@reddit
A/C is really only required when the nights don't cool down below around mid-60s F. I like to have blackout drapes on the sun-facing windows to block the direct heating and then throw everything open once the sun goes down. Where I live, mid-June to early September is usually A/C weather, especially during the day.
Malicious_blu3@reddit
Times like now I want to have my windows open but then I wake up not being able to breathe or see. The pollen’s been brutal.
dijoncatsup@reddit
Yes, but I really shouldn't because there's too much pollution near me.
ImportantSir2131@reddit
Yes. We live very near the water, get a nice breeze. When it hits the 80s, the windows get closed and the AC goes on.
OddPepita@reddit
Seattle here…our weather is similar to a Mediterranean climate…dry, sunny summers with cool temperate nights that are pleasant save for a week or two where we might get 90-100 degree F. My second floor windows are open all summer, all day. No AC needed.
rosycross93@reddit
I prefer fresh air but once the house gets stuffy we turn on the a/c. Unfortunately it works too well and I’m often cold. But my boyfriend likes it cooler. I’d be fine at 78.
Prometheus_303@reddit
Lüften!!!
As long as it's at least 10° we'll usually open the sliding glass door (just the glass door not the screen) so the cats can watch the chipmunks and birds and whatnot...
Once it's warm enough I'll usually open my bedroom window and leave it open for the rest of spring, summer & fall until it starts to get too chilly again... The cats like sitting there (especially at night when my desk light attracts moths to the window screen). And a cool summer evening breeze hitting my back as I mess around on the computer at night is nice.
If it gets too unbearably hot we will shut things up and turn the air con on to cool things down... But that's maybe just a collective week or so throughout the year.
cdb03b@reddit
80s is spring temps here. There are maybe 4-5 days in March when it is not raining that I could open the windows temperature wise, but everything would be covered in pollen so that is not acceptable. AC is kept on year round and switched to heat when temps get below 50.
Bored_Accountant999@reddit
Yes. I open my windows any day that it's nice.
I turn on the air conditioning when I'm hot.
salmonstreetciderco@reddit
i even open the windows on days that aren't particularly nice! i'd rather be a little chilly than stuffy and stinky. our house is quite small and we have two young boys so some odors do accumulate!
Grand-Professional-6@reddit
Always. Spring to 80 degrees sounds about right.
justdisa@reddit
I open the windows for all except a week or two a year, but I live in the Pacific Northwest where it rarely gets hot.
DefinitelyNotEmu@reddit
Air... conditioning?!
Quirky-Invite7664@reddit
No. Too humid and too much pollen.
Electric-Sheepskin@reddit
I do, but there's a very small window where I live, because the pollen gets insane, and by the time it's all finished and washed away, it's quite hot out.
underscore197@reddit
I’d love to, but we have piles of pollen (I’m not exaggerating) in the Spring and you do not want that in your house. In the Fall, however, absolutely.
FancyPickle37@reddit
I leave windows and doors open pretty much all summer long once temps stay 75+ during the day. Rarely use the AC but in the wintertime the heat stays cranked up. I can’t stand a cold house!
Trippy-jay420@reddit
I keep them open until the humidity hits. Once it feels like soup outside, AC goes on. Fresh air is underrated though. Most people forget.
NameOk9041@reddit
Los Angeles : yes.
COGARAGESdotCOM@reddit
I live in the Rocky Mountains without the need for air conditioning, so yes. June-Sept the windows are rarely ever shut.
ca77ywumpus@reddit
If I'm home I open the windows until it gets to about 80 degrees. In the late summer the air quality is usually too poor to have the windows open. I don't leave the windows open when I'm not home because my neighborhood is safe, but not that safe. Plus my cat is fat and stupid and could push the screens out.
197708156EQUJ5@reddit
I’ve lived in a bunch of different parts of the U.S., and honestly… the answer varies a lot depending on where you are.
Northeast (coastal, many years): AC wasn’t really a big thing where I grew up. I don’t remember having it at all through my early 20s. We’d just open windows and use fans during the ~30 or so days each summer when it got uncomfortable.
Northeast (near the Great Lakes, many years): Here it’s more about humidity than temperature. We’d usually turn on the AC once it hit around 80°F (27°C), because that often comes with ~80% humidity and suddenly the air feels… chewable. That’s maybe 30–40 days a year.
Florida Panhandle (Feb–July): Completely different beast. Around early May (like May 5th), it felt like breathing underwater and never really let up. AC wasn’t optional, it was survival. Was that way until I left in early July. I still remember seeing on the bank sign 100° F (38° C) and 100% humidity.
Honolulu (about 14 months): Funny contrast here. The military barracks always had the AC blasting, but I’d open the door/windows a lot because the warm, humid air actually felt nice outside. Inside was so cold that even flies seemed sluggish 😄. In the general Honolulu area, it never seemed to rain, but go a few miles up toward the mountains and it seemed to rain all the time. I still remember seeing blue sky all the way to the mountains, about 10 miles (16 km), blue sky all the way out to the ocean, but feeling the rain drops, at times heavy.
Southern California (San Diego, ~20 miles inland, 2 years): You get maybe ~10 weeks a year where you don’t need AC. The rest of the time, it’s pretty warm and dry, so AC gets a lot of use.
⸻
General rule of thumb (at least for me):
The U.S. isn’t one climate, it’s like 5 different countries duct-taped together weather-wise.
seriouslea@reddit
AC is not common in my area. We leave then open all summer when it's hot. Or open at night, and closed during the hot part of the day when it's very hot.
sfdsquid@reddit
Yes.
As for AC, I can't afford to cool the whole apartment because it's too open. We only have AC in the bedrooms. So when it's really hot we usually have the windows open and a few window fans going.
Leverkaas2516@reddit
In the PNW, I have an upstairs bedroom window that hasn't been closed in years. If it's really cold or driving rain, it's only open an inch or two, but 8 months of the year it's mostly wide open.
CalmStrongTornadoes@reddit
Allergies and humidity demand I mostly keep windows closed.
lt150@reddit
In San Francisco, opening the window is the AC. 🤣 A lot of apartments/ homes don't have AC. I keep a couple of windows opened/cracked year round. Love the fresh air. Only a few days a year gets hot enough that I wish I had AC.
alwaysboopthesnoot@reddit
We open them randomly throughout the year if it’s not wet, freezing cold, or a high pollen/dust kind of day.
We try to do without the central a/c but being near the ocean and river pr in Summer we do resort to that, or it’s too hot and humid to be comfortable and is pretty hard on my asthma (and on our older pets).
Carbon-Based216@reddit
I have allergies in the spring and fall when the weather is nice enough to do that. And I just rely on AC in the summer. So I rarely open my windows up for long.
ThrowawayMod1989@reddit
It’s called burping the house.
Sparklykazoo@reddit
First thing I do every morning is fling open all the windows (when the weather isn’t too hot or cold). Fresh air is best!
pastrymom@reddit
There’s too much pollen for this. Some is visible and will coat your home in yellow, the other is too small to be seen with the naked eye. I’ll get sick.
Glum_Courage_6330@reddit
I open the windows for an hour every day it’s over 50 or under 85 degrees outside. I like the way it makes the house smell fresh even if it’s a little cold. During warm months I can usually get an hour in the early morning which is so nice
Vikingkrautm@reddit
I have my windows open most of the year in Washington State. When it gets too hot, I close them, close the curtains and all the doors, outer and inner.
KurleFry@reddit
Yes windows are open at the first sign of nice weather and I do open them here and there if the weather is cool. AC is normally on 24\7 once my sweating at night. Would turn off for cool weather while windows are open.
towblerone@reddit
i like my house cool, i don’t handle heat well. i’ll open my windows up to around 65F, any higher and i close them because my house is insulated pretty well and will keep cool in and hot out.
once it’s consistently 84F or more every day, that’s when i put the ac in the windows. i try to wait until 84 ish because sometimes even if it’s hot during the day, it cools off pretty well at night, so i open my windows overnight and close them in the morning to keep the house cool during the day.
Neither-Attention940@reddit
The only wonders I can easily open for this purpose are a bathroom window and a kitchen window. Yes we open them but they are both very small.
We have a window AC in our bedroom and it goes on a large part of the year because our room is warm and it’s too hard to sleep. It stays on all night.
If it’s much into the 70s the house gets too warm but generally we don’t go into full AC mode till it gets into the upper 80s or 90s out.
This year for easer it was actually really warm out and we had a house full of people so the AC came out sooner than normal.
kae0603@reddit
We keep them open until the humidity hits. I can enjoy warm weather, but not humidity.
NoMonk8635@reddit
Isn't that what windows are for
Forsythia77@reddit
I have a very low tolerance for being hot so my AC is on once it's about 80. And if it's humid, forget it. AC keeps the humidity out.
superkt3@reddit
Boston area, the window has been cracked open on and off over the past few weeks but we have swung between snow flurries and 80 degrees in April. The windows are open most of the summer, as it usually cools off during the night, but there are weeks in July and August where we have to close up and crank the AC to fight the heat and humidity.
drumzandice@reddit
I love having my windows open as much and as long as possible. I put off turning on the air conditioning as long as I possibly can but when the hell starts to get really humid I can’t sleep very well at night.

Florida here. Windows open in spring and fall. Close them when the AC or heat kicks on.
kitchengardengal@reddit
When I lived in Northwest Indiana, near Lake Michigan, I'd open all the windows in the house (41 windows!) on a nice spring day before the bugs returned to the yard. I loved having that fresh, clean cross breeze through the house.
Since I've lived in Georgia for the past 20+ years, I rarely open a window. Some of my windows don't have screens, and there's NEVER a bug free season in Georgia. Plus, the pine pollen is so heavy in spring, it leaves a layer of pollen dust everywhere.
When my BIL was in the US Navy, stationed in Virginia Beach, the pollen was stuck down to the cars because the jets would dump fuel, which would vaporize up in the sky and fall down and stick to the cars and everything else outside. When he tried to wipe off the pollen, it was a greasy smeary mess with the fuel and pollen on it.
kkrolla@reddit
Always and when it's humid. Heat I can take. Humidity makes me feel like I'm dying.

JosephBlowsephThe3rd@reddit
In NC, that's a gap of about 2 days, then it dips back into highs of 60s for a couple days, back to 80, then we get 2 days with lows resulting in frost, repeat the entire cycle for the next 2 weeks with random jumps in temps before leveling out to 80s and up all the way until late September.
More importantly, NC in spring has daily pollen that, at best, is omnipresent, and at worst is thicker than the fog in Silent Hill and can be seen moving as if it has gained sentience.
Zornytoad@reddit
NJ resident -this is one of the few times of year (maybe 6-10 weeks total out of the full 52 between spring and fall) where I can leave the windows open for part, or the whole day. It’s nice, the pollen can be bad though. From maybe late May through maybe mid September, it’s too hot/and or humid. Then, mid October through to next early April it’s too cold.

ericbythebay@reddit
Sometimes. But, I have allergies and prefer to leave the windows closed so the air exchanged with the outside goes through the HEPA filters first.
Generally, I close windows when it is hotter outside than inside. Or when it gets too cold at night to leave them open overnight.
MakeStupidHurtAgain@reddit
Yes, always in the morning when it’s cool. When the temperature in the house gets to 80F/27C, I close up and put the air on. Given that we’re above 100F/38C for months, it keeps the electric bill down.
Lucky-Bonus6867@reddit
If it isn’t raining and the temp is roughly 60-75 F, my windows are open. Sometimes in the spring, I’ll leave a few open at night at colder temps.
80s are too hot for me, personally. But I’m fortunate to have decent AC and good insulation.
jvc1011@reddit
Yes, in the morning and evening.
During the heat of the day, it just makes things hotter.
This used to be the only kind of cooling people had in our part of the city, but climate change has made it hot and people have had to adapt to AC systems.

Yes? When to close them depends on heat, humidity and the last few summers how much wildfire smoke is in the air.
Historical_Badger321@reddit
I open windows when the outside temperature and humidity are nice. Otherwise, no.
My place is well shaded, so it can get into the lower nineties outside and it's still comfortable inside. But once it gets humid, the AC goes on.

I open my windows every night all year long, except in the depths of Arizona summers (June-August) when even the nighttime lows start to rise above 80. I like to keep my indoor temperature in the 74-77 range.
DrGlennWellnessMD@reddit
I would, but the temperature bounces up and down so much that it's not as simple as "open windows on X date and close on Y date."
And more than anything, humidity is a factor. In the rainy spring, opening windows even on a cooler day could mean the dampness factor in my house skyrockets.
Bad_wit_Usernames@reddit
I live in Las Vegas so our "nice" weather doesn't last very long. And it's often accompanied with strong winds. Having said that, yes. I open my windows in nice weather. But I also leave them open during most times of the year. If anything, just to get air flow through the house.
Summer, winter, I have usually at least one window open. It's more likely I close it during windy days due to all the sand/dust that gets into the air.
Arievan@reddit
Yes I open mine almost every day. I don't have a/c and I don't know anyone who has more than a window unit
SnazzleZazzle@reddit
I open the windows on any nice day regardless of the time of year. I also have my bedroom window open at least a little bit every night, all year regardless of weather (I share a bedroom with the husband, two dogs, and a big hairy cat) so fresh air is important so I’m not breathing in all kinds of fart fumes.
I don’t put the AC on until it’s bad - super hot and humid for more than a day or so. Once it’s on, it stays on until we have a good stretch of cool weather. Honestly, I hate running the AC, I prefer open windows and fans, but I have to accommodate the whole family, not just my preference.
Elaine330@reddit
Its too noisy in the suburbs to sleep with them open especially if you want to sleep in. But anytime I can during a day I open things up.

I live in CA, about 30 miles inland from Monterey Bay (as the crow flies). I’m lucky enough to have great weather and even when it’s been 100°F in the summer, I can usually still open the windows in the evening, when the sun goes down, and get the coastal breeze! We only get a few 100°f a year, usually it’s about 85°. We open windows in the morning, close up about 9am or 10am, open again when it’s cooler outside!

I love to have my windows open as often as possible. Thankfully I do not have allergies. Some years they’ve been open 2 months in the spring and 2 months in the fall, and other years only a couple of days when the weather seems to go straight from cold to hot. If the humidity is low, I can wait until the outdoor temp is 90. In high humidity I’ll turn on the AC at 80 degrees.
Saltpork545@reddit
I sure do. In spring and fall I tend to keep my windows open for days at a time.
Right now it's like 65 and raining and my windows and porch door are open(with a screen door).
I tend to close them and turn on the AC around 85. Just too warm. Same with around 50. Too cold.

I may open the windows a few days during the spring for fresh air, but because of pollen, I don’t leave them open for days. I live in the Deep South, so air conditioning is a requirement.
shibasluvhiking@reddit
Open windows as soon as it is warm enough. Fans if it is warm, I only close them and use AC in the bedroom if it is affecting my sleep or in the main living space on the ,usually, rare day that indoors is above 85f mainly for the sake of my double coated dogs. The climate where I live allows this. In the US some of this depends on where you live since we have many different climate zones. 90f days tend to not be too common where I live.
Melodic_Pattern175@reddit
Depends on the weather. It’s def not seasonal, because summer days we’ve already been up to 90s, and other days in the 60s. On the latter days, windows open no problem, but not so much when the heat gets above mid-70s. It’s also very humid here and we rarely have a breeze. 😢
OkOccasion5397@reddit
We don't open the windows as often due to pollen and smoke pollution from Canadian wildfires.

"nice" temps mean the pollen is in overdrive, so no. I like not dripping snot, tears streaming down my face, and headaches.
Also, it's April and it's already been 95 where I live. So spring isn't really spring anymore here.
March is nice, I guess. Except the weird days in the 30s that pop up every year.
Astronaut6735@reddit
It depends. I'm very allergic to tree and grass pollen, so I leave them closed early spring when trees are pollenating, and early summer when grass is pollenating. Where I live (Maryland) summers are humid. Opening the windows lets in humid air, which makes air conditioning work harder and use more energy, and feels less comfortable.
Carinyosa99@reddit
I definitely open my windows when it's nice out and will even open them a crack if it's in the 50s. I need to get some fresh air in my house. But I now get direct sun in the front of my house because we had to remove our large shade tree (it was dying) and it makes it quite warm inside and I have carpet so it just feels warmer and I'm very uncomfortable. Last month when we had unusually warm temperatures, I held out on turning on the AC but I wasn't always happy about it. But earlier this month, after a couple of days being in the 80s outside and my house constantly being around 75-76, I needed to turn it on. But this morning it was in the 50s so it's off and I opened up the sliding door in the back a little bit to get some fresh air in.
Cache-Cow@reddit
I try to open them whenever it’s cooler outside than my AC’s set temp and leave them open until it warms up more than my ACs set temp
sparklyspooky@reddit
There is a sweet spot in spring around here between 4 and 7 am. But otherwise we would be leaving them open overnight and I don't want raccoons in my kitchen.
TipsyBaker_@reddit
In the main part of the house I've been leaving them open at night for the cool air. I'm about to close everything up though, it will be in the mid 80s by 11am. This house holds on to heat like it's a job and takes too much to cool back down.
DarthMutter8@reddit
I like to keep them open until the humidity ramps up or it is like the upper 80s. My husband does not so we meet in the middle usually. I have windows open as long as I can. Even in the summer, I will open the windows for a bit in the morning or at night when it cools down.
BuildNuyTheUrbanGuy@reddit
Only in Colorado.
ChanFry@reddit
I used to. And if I ever move to a more remote area, I'll do it again.
But now any time we open the windows, it's simply too noisy outside. At the bare minimum, neighbors' AC units are running on both sides. During the night, random dogs barking for hours, occasional modified mufflers sounding off. In the day, kids screaming, dogs barking, big trucks idling, half a dozen music tracks thumping, neighbors walking past with speakerphone conversations...
It's too much noise.
Not to mention the dust and pollen — I can set something clean on the back porch and two hours later it'll be covered with whatever is in the air.
1996Tomb_Raider@reddit
New England - windows open when we’re home. When it gets wicked hot and humid central air goes on.
Electrical-Ad1288@reddit
I do it whenever it isn't super hot or cold. I often leave my patio door open all day since it is a 3rd floor apartment, making break ins unlikely.
El_Culero_Magnifico@reddit
Where I live, we have hot , dry summers days and cool nights. I typically have doors with screens ( we have 4!) and windows open all night to let the cool air in. Mid morning I close everything up to keep the cool in and the heat out. It works really well. We don’t have or need a/c , the house is shaded by large oak trees most of the day.Then ,around 7 or 8 pm, I open everything back up again.
Quirky-Lecture-6066@reddit
We used to open windows in the spring often, but my youngest son is very allergic to trees (he does antihistamine liquid, an eyedrop, and a nasal spray daily this time of year). We try to keep the pollen out.
ReciprocalPhi@reddit
When the outside temp and humidity is pleasant, the pollen is fucking crazy. Every time it rains, my car is yellow/green with pollen the next day.
No, I don't open my windows. I wish I could, but there's no point in the year where it's a viable option
ChemicalCat4181@reddit
I open my windows most days. I rarely turn on the ariconditioning to be honest. It getting hot hot is rare here though.
theegodmother1999@reddit
if i want fresh air i simply go get it where it's freshest, outside. and then go back into my AC pumped house. it gets very humid and hot here
ScienceMomCO@reddit
Yes, until the daytime highs are in the mid-70s, then it’s time for the AC
eugenesbluegenes@reddit
I don't have air conditioner so yes, I open the windows when it's nice.
letsplaydrben@reddit
I prefer fans and the fresh air, but my dogs bark at every little sound outside. I turn on the AC as soon as it gets into the high 70s.
outloud230@reddit
Humidity is a factor, but mostly pollen. I’m allergic to trees and grasses, so my windows stay closed during spring tree-sex orgy time. Fuck pollen. Summer is too hot, winter too cold, but autumn can be lovely.
finethanksandyou@reddit
As soon as it’s in the upper 40s to low 50s (F) overnight I leave windows open round the clock. Her in Michigan it then gets wildly humid making it a misery in the heat. Then A/C without much cooling to dry it out! Only crank it up in late June/July/August
Iowa50401@reddit
I open the windows until my wife starts complaining that it's too hot or too humid.
jessper17@reddit
We open them for the day if it’s like 60° out and we’re home but we don’t keep them open. Allergies + weather changes + open windows are a bad combo.
lifehackloser@reddit
All windows all summer because we don’t have ac. The trick here is to open them overnight and early morning. Close them up before it starts warming up. If it’s windy enough, open up opposite ends of the house for a nice cross breeze.
qu33nof5pad35@reddit
Ehh, sometimes. I only have one window and it only opens up 4”. I typically open it when I’m cooking or if it feels stuffy inside.
GratefulTrails@reddit
I live in a cabin in alaska with no AC. My windows pretty much stay open from late May to early December. But im originally from Florida and Texas. Windows stay closed and the AC on unless the temps drop below 65 degrees and its not cedar or oak pollen season because you will have a film of yellow dust over everything you own.
Kelly_Louise@reddit
Where I grew up in Montana, in the summer we opened all the windows every night and closed them in the morning to get a nice night flush that kept the house cool all day. We didn’t need AC. Now I live in Boise Idaho and it gets really, really hot in the summer. And it doesn’t cool off at night like it does in MT. So unfortunately, we keep the windows closed and use AC. Right now, we open the windows every now and then since it is spring and it’s cool outside. But it won’t last long. The 90-100+ degree days start in June and last until mid September.
Strange-Employee-520@reddit
We almost always have windows open unless the air quality is bad. I close them when we're out all day to cut down on allergens and dust.
burningmanonacid@reddit
I'm in Michigan where it never gets warm enough, but it does get to 100% humidity. The humidity governs whether they're open or closed more than actual temperature. I can't stand a damp house. Lol
AllAreStarStuff@reddit
I live in Houston. There’s a very short span of time when the weather is not too cold, not too hot, and not too humid. On those days, we leave the bedroom windows open at night and the back door open all day when we’re home. Our cats love it. We built a little brook in our backyard and it’s wonderful to fall asleep listening to it. When the inside temp of the house is around 76-77 or it starts to feel muggy, it’s time to close up the house and turn on the A/C. My husband and I disagree on where the threshold should be 😄. I prefer to suffer a bit because the house feels so stuffy after being sealed all summer and winter.
Rum_Running_Sailor@reddit
Yes. Once inside temp hits 80°F, the windows close and the AC goes on.
JustAnotherUser8432@reddit
Sometimes I open windows in the winter too just for fresh air and then let the heat catch back up. But yes, we open windows when it is nice. Have been for the past month or so off and on.
As long as overnight lows are below 70F (and like more than 50F), we leave them open at night. In the summer, we close the windows in the morning, pull the shades on the south side so the sun doesn’t come in and the air conditioning kicks in when the house reaches 77F.
AC stays on if it is super humid because it does a great job of getting the humidity out of the house air or if there is a lot of wildfire smoke in the air since it is unhealthy to breathe that and the furnace filters do a good job of filtering it out.
waitingforgandalf@reddit
That's about what we do, although it's rarely humid in the summer where I live. It also almost always cools down below 70 at night so lots of fresh air in summer, and we start opening the windows for at least a little bit when the high is over 60, so we have the windows open regularly for almost half the year.
redvinebitty@reddit
Always windows til house too hot. Open at night to cool. But that’s desert, windows at night doesn’t work in Florida
suffaluffapussycat@reddit
Southern California here: windows are open a lot of the time. A/C only on the very hottest days.
sitewolf@reddit
I've been known to open windows in first days in the 50s in the spring just to turn over some of the air after a winter. Otherwise on warmer days, windows open until temps hit room temp
IHSV1855@reddit
Yes, but weather here is far too erratic to open them at some point and then close them when it gets hot. Yesterday it was 75 degrees when I left for work and 35 when I came home.
We open and close them throughout the day depending on temperature. Sometimes they’re open for a few hours, stay closed for a week, then are open all day every day for the next week.
stephsationalxxx@reddit
When my dog starts panting, the AC goes on.
My windows are open year round bc the heat is too hot. I live in an apartment building with no thermostat. I can turn the radiators on or off but the heat also radiates through the walls and its suffocating so I keep my windows open to help regulate the temperature.
joehart2@reddit
Everyone is different. I tend to like it cooler than most.
I can’t install & use my window A/C until June1 each year, per landlord.
So, I “time” my window opening, & fan use perfectly. Usually below 50°F & above 70°F, I close the windows.
I need to also respond to the sun, close shades when beating down.
(Yes, I’m OCD. Yes, I have time to do this. Haha.)
shessocold1969@reddit
We don’t have A/C. We rarely need it. Maybe 2 weeks out of the year I wish we had it. We moved into new construction 25 years ago and the baby trees are now huge and provide a lot of shade. It doesn’t get as hot as inside as it used to. If it isn’t freezing cold or raining heavily the windows are open. I love fresh air.
LaserBeamsCattleProd@reddit
I'm in Florida.
We pop them open for a few months in winter when it's cool outside, March through November requires AC most of the time.
MrsMitchBitch@reddit
We don’t have AC so, yes: our windows are open and stay open. Once it hits a sunny 50F or so, we start opening windows.
OkTransportation6580@reddit
I always open up the house with nice/cooler weather.
I usually close up when around 75f outside and turn on the ac. I have an old house and 75 outside means it's over 80 in our bedrooms which is an absolute no.
Successful_Way_3239@reddit
No, there is to much pollen and pollution in the air. I rarely if ever open my windows.
Emotional-Clerk8028@reddit
Yes, I'm currently enjoying a cool breeze with windows open, here in central NJ, 55°F.
We had a few hot days recently, but did not turn on the AC. We kept windows open and ran the ceiling fans.It's only April for God's sake.
Altruistic-Aide-9002@reddit
I leave windows open now but rarely opened them when I lived in Virginia. Virginia is buggy and humid with lots of pollen. The mosquitoes would find their way inside through the screens.
splorp_evilbastard@reddit
It depends where you live. Here's the three placed I've lived:
Southern California on the coast? Absolutely. I literally left my windows open almost year round when I lived on the beach in Oxnard.
Central Ohio? Mostly depends on the humidity. I've had ours open a few times already this year. But, then it literally snowed, again.
Austin, TX? Almost never. The temperature is usually too hot. When it's not, the pollen makes it ridiculous, especially if you have household members with allergies. The AC can run at almost any time of year. "summer" can start as early as March and run until as late as October.
In other words, like almost every other question I've seen here: it depends.
MassConsumer1984@reddit
Of course, yes. Drive by right now and all of my windows are open.
AC - When it gets way too hot and humid and sleeping is uncomfortable (90 degrees and up for me).
HotButteredPoptart@reddit
We only have AC in our bedrooms, so the windows are always open when it's warm.
Neat_Cat1234@reddit
We have windows open every day of the year. My husband enjoys the fresh air. We’re near SF and our weather is mild year round. Most of the houses near us have no AC.
dth1717@reddit
Michigan, I like my windows open all summer unless if it's over 90. But my wife gets irritable when it's over 80...
Apocalyptic0n3@reddit
I leave my A/C on year-round. I never turn on the heat.
During the winter, I basically have my windows open all day. During the summer (often starting late March/early April), the windows get closed and don't open again until winter (mid-November ish). I'll usually air air out the house with box fans once or twice during the summer and the windows will be open for a few hours.
Yeahboyeah@reddit
AC on when it gets above 80 consistently. Windows open if gets to above 65.
ivhokie12@reddit
Mostly no on the windows. They are old windows that were painted shut decades ago and the bug/pollen are bad even in the best of times. With new windows that were sealed properly I probably would.
Important_Canary6766@reddit
I do open my windows when the weather is good. I live in an area with high humidity and lots of pollen and rednecks who like to burn crap all day so I can only keep them open occasionally when the conditions are perfect. The one annoying thing about opening my bedroom window at night is the bird start chirping super early and wake me up at like 5 AM.
_NEW_HORIZONS_@reddit
I live in Central Virginia, and we had about 1 week of weather that would've been suitable if it hadn't also been pollen season. Highs in the high 80s, low 90s, now, and everything is still coated in yellow-green dust.
Positive-Avocado-881@reddit
Yes, but they’re closed now because of pollen. Once tree pollen is done I’ll start opening them again until it gets too hot
FrenchFlauta@reddit
My windows are open almost 24/7 year-round. Didn’t realize it’s so rare for some people to open their windows, that would drive me insane.
upnorthhickchick@reddit
When it finally gets warm it’s open them all at night and close in the morning. Ceiling fans instead of A/C.
Fun_Independent_7529@reddit
We live in the Seattle area / PNW and the windows are open (and doors with screens) for fresh air as soon as it's warm enough -- usually April through October. We don't have AC in this house, so if it's going to be a real scorcher, which doesn't happen very often, we do shut everything up mid-morning, pull all the blinds/drapes/etc and turn on the fans to try to keep it from getting oppressively hot inside.
I'd rather be a little too warm or too cool with fresh air. Always relieved when winter is over and we can reopen the house!
Defiant_Finger4011@reddit
Oh yes we open our windows any chance we get. Fresh air in the house is nice
Competitive_Web_6658@reddit
I don’t have central air. I could get window or floor AC units, but I live in an old, well-insulated house with exactly 1 outlet per room. I open the windows at night to bring in cool air and generally leave them shut during the day, when it’s hot and humid.
MissDisplaced@reddit
I open them for a brief time in spring before it gets too hot and before all the bugs arrive. Basically, April.
NarrowAd4973@reddit
I open them when temps are from 75 to upper 60s.
Traditional-Let9530@reddit
Yeah people still do, but once it gets hot or humid enough that AC feels easier than fresh air, windows stay shut.
lcrx97@reddit
The rule of thumb is open them when it’s cooler outside and close them when it’s hotter inside. I turn my ACs on when it’s late April and consistently too warm or humid in New England to rely on windows
FlippingPossum@reddit
I aired out my house on a nice day about a week before the great pollening. I'll open for several minutes after deep cleaning in cooler weather. I do not on humid days.
I have asthma and I'm allergic to dust mites. A delicate balance of airing out and not irritating my lungs.
RickLovin1@reddit
Almost never. It would be nice from time to time, but in the spring, the pollen is ridiculous in Georgia. Then the heat/humidity takes over. Not only that, I live near a fairly busy street and once the weather warms up a bit, the loud ass motorcycles come out.
whatevendoidoyall@reddit
I live in Denver, I pretty much leave my windows open 24/7 in the spring (unless it snows).

morganalefaye125@reddit
We open one in rhe kitchen, one in the living room, and one or two in the back of the house. We have a large fan that we turn on, and it circulates a wonderful, cool breeze. We usually hold off on turning the AC on as long as possible. We have central air/heat, and it blows up our electric bill when we use the air. It gets turned on once it's over 80 degrees in the house. So far, it's gotten to 78. It's almost time
river-running@reddit
Similar for me. They're open all the time in the spring and fall unless it's raining. Also open at night during the summer and sometimes during summer days if it's not too hot or humid. I'm in the South, though, so those days aren't too common.
In the summer, I close the windows and turn on the AC when the inside temperature hits the low 80s.
Odd_Mathematician654@reddit
We open on nice, non humid days. But there are few days like that between May and October. We have a cat that recognizes the windows open conditions and comes and paws at my home office window for me to open to allow him to sit on the windowsill.
BurritoDespot@reddit
For most Americans: never. They have essentially no touch with what’s going on outside beyond the walk from their car to wherever they’re going.
aracauna@reddit
It's a really small window for where I live. From December to February, it's a little too cold and from April to September it's way too hot. It's been over 30C for most of the last two weeks, for example. You get a few nice days in February and April, but March and October are really the only months where the weather is similar to what you want room temp to be. Usually, I'll turn off the AC those months and open windows, but this year the pollen was so heavy that it made me sick and I wasn't about to bring that inside. (Parts of the US are famous for heavy pollen in the spring that coats everything outside in a layer of yellow powder and this spring was even worse than normal.) October doesn't have that issue.
Another problem is that the bugs in the southeast are insane. If I don't have good screens on the windows or a screen door, I'm going to have a house full of the native flying cockroaches, flies, moths, and be covered in welts from the swarms of mosquitoes. And then the humidity. Humidity in the summer is so bad paper gets damp being outside on a sunny day from absorbing moisture from the air. My AC helps dry the air out. Because of that humidity, lows at night are often in the 80s F (27-31C), so during May-September it's not even ideal for having them open at night.
Bulocoo@reddit
I love spring and fall. Windows open between about 65 and 70.
In California the upper was probably 80.
Here in FL it's too humid.
When ac goes on it stays on at 68.
Winter heat is 65.
ShowScene5@reddit
I live in Florida. Ill open them for a few days in the winter, other than that its AC 24/7
No_Entertainment1931@reddit
Open windows and sliding doors and leave them open as soon as evening temps stay above 68f. I only use ac above 92f.
Emotional_Match8169@reddit
Upper 80s you say? May I ask what area of the country you're in? I am guessing somewhere that does not have humidity issues because that would be inviting mold to move in where I am at.
I live in Florida. So I open my windows in the upper 60s and below. Anything above that and it is typically too humid to keep the windows open.
atheologist@reddit
I prefer windows open in nice weather, but traffic noise and pollen can make that challenging in NYC. I use air conditioning as little as possible, though; except for the hottest weeks of the summer my ceiling fans generally do the trick.
thedawntreader85@reddit
Yes, I have the windows open as much as possible. It cuts down on the electric bill in the spring and the gas bill in the fall.
In spring to summer I turn on the AC when I start having trouble sleeping due to the heat, usually around 80°F and in fall to winter I turn on the heat when all I want to do is cocoon in blankets all day and I'm not getting chores done, usually around 45°F.
Free-Sherbet2206@reddit
The weather is rarely nice where I live, so I basically never open my windows.
DangerousBlacksmith7@reddit
I do until it get too hot outside. I also live in a apartment so I don't really get any air flow except when I use a ton of fans but it's still hot.
I usually turn on the ac around end of May beginning of June. But it's all depends on how hot my second floor apartment stays.
w3woody@reddit
When we used to live in Glendale I did this all the time. As soon as it got warm outside, I'd close the windows and turn on the air conditioner.
Here in Raleigh I don't--but that's because none of our windows have screens on them, nor do they have a way to easily attach screens to them. Which I find stupid and incredibly irritating, because Raleigh is definitely buggier than the Los Angeles area.

Ayla1313@reddit
For me on the East Coast it really depends on humidity level and how warm it gets at night.
A low humidity 80 degree day is way more tolerable than high humidity 80 degree day and once it hits 65 degrees at night that AC is getting put in the window.

The weather has been up and down a lot where I live, so some days the windows are open but the very next day it could be so hot that we need to shut them and put the AC on. I actually open my windows in winter too but after it hits around 85 I can't handle it (not a fan of the heat).
There is also the matter of pollen.
BankOk9472@reddit

ThatCrossDresser@reddit
I have a couple of different modes.
0 - Windows Closed, it's too cold out. 1 - Windows Open, it is a comfortable temperature all day but close at night because it is too cold. 2 - Windows always open and fan in Windows. During day fans don't run but run all night long to cool house for the day. Upstairs fans blow out downstairs blows in. Keeps house cool for most of the day. 3 - Windows Closed when it gets too hot for the fans to keep the house cool. Air Conditioning on.
In my region we only end up in 3 for about 6 weeks a year. The rest of the summer and spring option 2 works fine.

rectalhorror@reddit
It's been in the upper 80s/low 90s this week. I turn off the lights, turn most of the shades down, and open the windows on three sides of the house. Floor fans and hassock fans circulate the air and keep it in the low '70s. I keep the bedroom windows open at night; the cool fresh air helps me sleep. Loose fitting clothing helps a lot. Grew up in DC summers in a house that only had one AC window unit in my parents bedroom, so I'm used to the heat. I miss when everyone would hang out on their porches in the evening and we'd chat with the neighbors and eat watermelon with a dash of salt and smell the mosquito coils.
itmightbehere@reddit
The weather where I live is extremely variable, so I might open my window some days, but more often than not, I don't. Like, we had a 60 degree temperature drop in 24 hours a couple weeks ago, so it went from 90s to below freezing within a day. Or the day will start nice, then halfway through we get a thunderstorm.
If the weather is expected to hold and the temp is about 60s to 80s, I'll open windows.
Electrical-Let-6121@reddit
Too much pollen in the spring
FormerlyDK@reddit
As soon as it’s hot enough to need AC. And open windows let in rain if you don’t have deep eaves, so it’s not like you can go out and leave them open if there’s any chance of it.
Ananvil@reddit
They're open once the temp is above 60. AC once my wife makes me, otherwise I would probably wait until it was like 90+
Whiskeydrinkinturtle@reddit

There are a lot of factors. Pollen, humidity, temperature, air quality. I have an attic dog that can't handle heat and a son with severe asthma. Due to medications I take, I have become very sensitive to heat. As soon as the temperatures hit 80, the windows are closed and the AC is on.
Md693@reddit
Yes finally prob around June
Mjslim@reddit
We don’t have air conditioning, so yes we open the windows quite often.
djmcfuzzyduck@reddit
I wish my windows opened in my apartment.
Oblivian69@reddit
In the spring/summer/fall I open my windows every morning at 6 AM. They stay open until around noon.
memily11@reddit
I open mine in the spring and fall, but it’s pretty soon before it gets too hot. But you would never see them open because I rarely open the ones in the front of the house. Side windows and back ones most often.
rainbikr@reddit
Open on the cool shady side of the house, top sash to keep rain out of that's the forecast. Blinds and shades closed on the sunny side with windows open just a little, for cross ventilation.
Haven't run the AC in over a decade. Too $
jda404@reddit
I don't have central air, just window AC units so I resist putting them in, especially in the bedroom as I have only one window in the bedroom, as long as possible because I like the fresh air coming in and once the AC goes in they're in until end of September which means can't open the windows that the ACs are in.
Usually in the spring I put them in sometime in May. I am in PA. We've had some 80-85 degrees day this week and I've thought about it putting one AC in, but still holding off. Tomorrow the temps are going back down. Tomorrow's high here is only going to be 50 degrees and all next week it's going to be in the 50s and 60s.
naked_nomad@reddit
Open them in the spring and fall until the weather dictates otherwise.
manicpixidreamgirl04@reddit
My windows have been open for the past few days because it's been hot and air conditioning in my building doesn't start till next month
AdamoMeFecit@reddit
Mostly open in late March/early April, and closed again in November/December.
Almost never run AC unless guests require it.
The only downside is the constant leaf blower noise from neighbors. All day, every day.
Financial_Emphasis25@reddit
I keep my windows open the most in spring and early summer all daylong. During the hottest parts of summer I will open the windows in the morning or evening and shut them at the hottest part of the day with the A/C on. I lived without A/C for 20 years before getting a whole house A/C system. It was absolutely miserable without air conditioning.
Creative-paintbrush@reddit
We open them all night and only close them during the hot part of the day… my family has always avoided using the ac as much as possible when my dads allergies get bad is when we use the ac
B00k_Worm1979@reddit
I literally just opened some windows before I saw this. Once it gets humid out, I’ll shut them. I love fresh air, but if it’s too humid, I keep them closed.
sebago1357@reddit
It's 58F in Maine right now. My windows are closed and the heat pumps set for 56.
meewwooww@reddit
Are you cooling to 56 or heating to 56?
I'm also in Maine. I have three cats and one demands we open windows. Usually one or two are open, as necessary, as soon as it's in the 50s.
When it's 60s they are pretty much open all day. Shut at night. Once it hits 80 they stay shut except for dedicated window kitty time.
Semirhage527@reddit
Yes - we usually open them in the morning and leave them open until just before it’s too warm out - then we close them and with that cool air moved inside we usually only use AC for a few hours at most
HeyaShinyObject@reddit
Open if it's cool outside, but not in pollen season (may/June usually)
Content-Car6395@reddit
Our windows are open now, temperature 60-70, humidity is low. During the night we close the windows and use ceiling fans. Also a tepid bath before bed helps cool body temperature.
BrookieMonster504@reddit
Never if I want to see the weather I go outside
shouldiknowthat@reddit
If I lived alone, I definitely would. My husband, however, is both asthmatic and allergic to many pollens, so windows remain shut.
GrouchyOldRN@reddit
I open them if it’s cooler outside than in. The pollen is awful, but the kids are grown. Between the two of us, we can dust and vacuum. In middle GA spring and fall are short seasons. I don’t want to miss the fresh air.
scallopbunny@reddit
My threshold for turning on the AC is when I am too hot/sweaty sitting still on the sofa, or if I need to do a bunch of more active things or have guests coming over
Active-Pineapple-252@reddit
No windows open and only use my ceiling fans during the spring and summer. I don't trust the air quality in today's world
If I have guests over I'll turn the AC on
MsPooka@reddit
There are 2-3 months a year I will open them. It's a bit of a pain because I open and close them every day depending on the weather so I get why people just leave them closed.
No_Water_5997@reddit
Mine are open basically from now to late fall. As long as it’s at least in the high 50s my windows are open. I don’t have central AC, just window units, and live in northern New England. I close my windows and turn on the AC if it get over about 85, which only equals a couple of weeks a year. I’m from Florida and have found that since living in New England I actually acclimate better to changes in temperature because we don’t use AC often so my body has to acclimate.
Ginger630@reddit
Right now in NY, it’s 55 and the windows have been open all week with this nice weather we’ve been having.
I won’t turn on the AC until we’re at 85/90. Or if the humidity gets bad. I try to hold off as long as possible.
I do turn the AC on in my car if it’s been sitting in the sun. It gets hot in there very quickly and I have kids.
My husband turns the AC as soon as it’s even a tiny bit hot. He runs hot and I run cold lol!
SabresBills69@reddit
the issue in opening a window or not are…
how humidity is it outside? you live in northern ststes or low humidity areas you can open the window and let air circulate. overnight temps can fall into the 50s which can cool down the inside of a home.
if you have pollen allergies it’s not the best idea to open windows
pinkbdlnds@reddit
No. I have a lot of allergies (pollen, grass, bees, etc) and it gets too hot here. Also, I can’t stand when bugs get in. I’d rather have my windows closed and blinds minimally open with the AC running 67-69 24/7
MortimerDongle@reddit
I open the windows when the outside is more pleasant than the inside. Generally, if it's in the 60s or 70s.
TTHS_Ed@reddit
NE Ohio. We open the windows in our bedroom and put one of those double fans in one window with the ceiling fan on and the door closed. We make it almost all summer doing that. I'd say we ran the AC overnight maybe 5 times last summer.
babyidahopotato@reddit
Always. I even have them open when it’s raining. I love to air my house out. If it’s a cool summer night I turn off the AC and open the windows.
SevereOrdinary2816@reddit
I like the fresh air but I am highly allergic to pollen and trees so I can’t open the windows from around April-July. Our heat and a/c are one unit and stay on auto all year. That’s what the company recommended. We just adjust the temperature to the season so it’s not constantly running.
Ok-Sport-5528@reddit
I keep the windows open until my allergies get so bad that my sinuses can’t handle it anymore, or it gets too humid and sticky. And on the east coast, sometimes upper 70s feels like the 90s because of the intense humidity, so it really depends more on that than the temperature.
poisonedkiwi@reddit
I start opening the windows once it hits around late 60s. I close them when there's a storm starting (very often these past couple of days...) or when I notice the house is too humid. We haven't used the AC yet this year, but that'll probably come on once the humidity gets worse, or the temps reach the 80s (whichever happens first).
venturashe@reddit
Always open them. I’m in a climate where the exception is to close them. We have no need for air conditioning. For those curious, coastal California.
RoundaboutRecords@reddit
As long as we can. Great Lakes region of NY stays cool longer. We only use our AC when it’s above 85 out which usually means humidity into the night. Windows open a lot. Love that cold morning air.
FivebyFive@reddit
Of course.
And often with the air-conditioning on.
(Our HVAC units are usually on, we set the temperature and if the house gets above it, the air starts blowing. It's below it, it doesn't blow. And vie versa with the heat. No reason not to just have the unit on all the time).
Jewish-Mom-123@reddit
We have gone straight from heat to AC this year because the pollen started early. It’s going to get cold enough today I expect to turn the heat back on. Sigh.
Cautious_General_177@reddit
If it's nice, I would. Unfortunately where I live, if the weather is "nice", there's usually obscene amounts of pollen. If there's no pollen, then there's an ungodly amount of humidity to go along with the heat (or it's winter and cold). So "nice" really isn't a thing here.
smugbox@reddit
Yes? They’re open now but I’m gonna close some because it’s cold in here and I just woke up.
We usually put the window ACs in when it starts getting hot regularly, so I guess around when you do. Upper 80s. But even then we’ll open windows if it’s not hot outside
Slippery-Pete76@reddit
I like to keep the windows open as much as possible - had them open for much of the last week, but temperatures are supposed to dip below freezing the next couple of nights, so closed they go….
WatermelonMachete43@reddit
Yes. We have them open when the temperature is about 58 to a daytime high of 82. If it is going to get higher than that during the day, we close them and the shades/curtains to keep the heat out. Cooler than 58, we keep them closed to keep the heat in. We don't have air conditioning, so the window (and fan) is how we regulate the heat.
nc2227@reddit
We do windows open through the house except a/c adapter in my sons bedroom. A/c in the rest of the house comes on once it’s consistently over like 85 degrees outside.
StarMan-88@reddit
When I lived in Texas, the AC was on year-round except for February when it's cold, and then it switches briefly to heat. Now that I live in New York, windows are open during spring and fall only when it's cool and AC gets turned on in the summer because it's too hot and humid outside.
WitchMatilda@reddit
It's 29* F here in Minnesota and I have several windows cracked. The fresh air helps me sleep and all around feel better.
outsideskyy@reddit
No because bugs get in, even through the screen
confusedrabbit247@reddit
We prefer fresh air as often as possible!
Inner-Confidence99@reddit
I do. Most people like air conditioning to much. I try to go as long as possible without it.
EnoughEstate7483@reddit
My wife keeps our house at 66 degrees +/- 2 degrees every day all year. We live in the NYC metro area.
AC runs when above 68, heat runs when below 64, windows can stay open when between 64 and 68.
CtForrestEye@reddit
The past few nights the windows were open as the daytime were up to 90f. We kept the temps in the 70s in the house. Now the house is closed. Tomorrow's highs will only be in the 40s. I won't reinstall the ACs for another month or more.
jckipps@reddit
The humidity and the nighttime temperatures go hand-in-hand. When both get high enough that I can't comfortably go to sleep, then it's time to close up and turn on the AC.
The daytime highs don't bother me much. If it's too hot during the day, close the windows to keep the cool nighttime air in the house, then open them again in the late afternoon.
We've had an unusual week here in Virginia, with highs in the 90s and lows in the 50s. The whole-house exhaust fan is on through the night, pulling cool air in through the windows. But once we get into August with lows in the 70s and the humidity that accompanies that, I'll be depending on the AC.
Ifyougivearagamuffin@reddit
I open them until my roommate complains and puts the AC on. I hate Air Conditioning, but I like my roommates more
SidMarcus@reddit
When the nighttime temps consistently stay >50°F the windows remain open 24/7 and I don’t use A/C, just fans to move the air.
Lugbor@reddit
If it's cool and breezy out, I'll open the windows. Once it starts getting above 75 or so, I start sweating and use the AC instead.
_handlemewithcare_@reddit
I do, but typically only at night in the win for some “airing”. I love sleeping in a cold room under a pile of quilts! Otherwise, it is almost always too hot and humid here to tolerate that (perimenopausal and getting too warm makes me irrationally agitated).
Individual_Check_442@reddit
I live in the desert ACs been on for a month already. I’ll turn it off and open windows some on the early morning late evening just to ventilate
Chance_Ad_2132@reddit
I have never opened my windows in my house
JackTheHerper@reddit
Nope, house is a closed system. 72 degrees, all the time. Only time a window is opened if when a particular south facing room gets too hot with the heat on, and it’s too cold to turn off the heat overall, so it just bleeds some heat from that particular room.
SeparateFly2361@reddit
I want to but I and my kid get allergy attacks with the pollen blowing in so we have to use AC
Right-Bathroom-7246@reddit
I’m in Florida- so no. Maybe 1 month a year is cold enough, tops!
Comprehensive-Tea-69@reddit
For me it’s the pollen. Right now when we still have cooler temps in morning and evening I would like to open windows, but then all the outside pollen comes inside. This is particularly problematic in the bedroom, but also getting it all over the couch is a pain too.
AnybodySeeMyKeys@reddit
Doors open. Our balcony is 50 feet up, so not a lot of bugs get in.
tiger_guppy@reddit
I’ve got screens on my windows so not a lot of bugs get in
AnybodySeeMyKeys@reddit
We do, too. But it's still nice to not have to fight them constantly because they don't fly this high.
CraftyFraggle@reddit
Windows get opened in the spring when the outside temp is warmer than the inside.
We don’t have full house air conditioning, only window units in the bedrooms.
In the summer, Windows are open if it’s cooler outside than in or if the airflow makes it feel that way.
babarsac@reddit
We keep the windows open whenever we can. We'll see how this summer goes with the elevated threat of forest fire smoke.
Apprehensive_Camel49@reddit
Too much humidity, too many flies, wasps, etc to leave them open for even a full day. But I tend to open our French doors around 5:30 most mornings in the spring and fall to get some fresh air in, enjoy some coffee and close them by 7:30-8 or so
thecardshark555@reddit
Northeast here. It's been hot the past few days...not putting on a/c. Right now, pollen isn't too bad, so windows are open. Its lovely at night when things cool down. I'll hold off as long as I can with the a/c but one of my kids has awful seasonal allergies so it varies each year.
tiger_guppy@reddit
It hit like 90°F here a couple days ago, we absolutely had to fold and put the AC on for just a few days. It’ll be off tomorrow when the temp drops again.
Ceorl_Lounge@reddit
Open at night to let in the cool air, closed in the daytime to keep the heat out. Works really well in Michigan since it's not uncommon to get lows in the 50s & 60s a good chunk of the summer.
Urawinner1945@reddit
We open ours in the SF area as long as noise or smell aren't issues, or if I don't want my cats knocking over stuff on my desk getting to the window. Also, if it's really windy (fairly often) or raining ( rarely) then we'll close them. But otherwise, temperature permitting, we open them.
Ok_Gas5386@reddit
Yes, I turn on the AC when the temperature gets above 88° F (31° C). I ran it for 3 1/2 weeks last summer. I like to use it as little as possible.
Tomahawk513@reddit
Yes. They’re open now. They get closed if the temp dips below 60 or above 80, or if the rain starts getting in.
johannaishere@reddit
Definitely. I lived for a long time with No AC at all but we had ceiling fans and a breeze from the window and the ceiling fan going was a dream on a hot day. Also an open window gets all that winter stink out and lets the house breathe.
We still don’t have central air in my current apartment but we have window AC units that we haven’t put in yet and probably won’t until at least June so right now is prime open window season.
_WillCAD_@reddit
Can't. I live in a ground floor apartment, if I open the windows, I get invaded by bugs of all types and sizes.
My previous apartment was on the third floor, though, and I'd open the windows every day during spring and autumn, probably four months out of the year. Saved me a fortune every year in HVAC, just ran a couple of fans to circulate the air.
Appropriate_Copy8285@reddit
When its over 70, abd sunny, everything is open, even my zipper.
Better-Refrigerator5@reddit
Yes. I don't have central AC so most of the summer we do windows open at night and closed during the day.
That plus ceiling fans more or less cover us (northeast). We have a window unit for heat waves though.
Chickadee831@reddit
Depends on the humidity and the pollen. AC goes on when it's mid to high 70s. I am not heat tolerant.
gardenofthought@reddit
It’s usually too humid to even think about opening the windows- central Texas
dangleicious13@reddit
I've never opened a window in my house.
notthegoatseguy@reddit
AC is already on for the last couple of days. We've been sweating pretty hard in our homes.
we finally put up the screens we took down over the winter and sometimes we do open windows but its not a thing we do often.
OneNerdyLesbian@reddit
We open ours and have them open now. We close them once its 80 degrees or higher for an extended length of time (as opposed to just for one day before falling again).
BallBroad41@reddit
year round both my bathrooms and one middle of the house window (rectangle trailer so far left, middle and far right parts have this) i leave open .5-1 inch
and then i let the heat and cooling tackle it, i also if its nice enough or want fresh air will crack the window behind my pc chair but yeah.
i would have them more open but i am near a highway and a busy railway so i dont want to have fumes blowing in full force lol.
handcraftedcandy@reddit
I only use AC is its in the upper 80s and humid. I don't really like using my AC, i prefer fresh air.
Traumarama79@reddit
I do the same as you. I enjoy the fresh air.
Haifisch2112@reddit
When I lived in Ohio, it got warm in the summer. Opening a couple of windows and putting on the ceiling fan would create a nice breeze.
Now that I live in SC, it gets hot in the summer. Opening windows means letting in hot air, making it uncomfortable. Also, pollen here is like napalm. I have a black car that turns green for a month. I'm not letting that shit in my house lol
Litzz11@reddit
I live in an area with high humidity. So the temperature isn't as important as the actual humidity level. When the nighttime lows are 65 or higher, that tells me it's too humid for the windows to stay open. Below that, I leave the windows open in the morning and at night and close them during the day to keep the cool air in. We have really good insulation in our house.
LABELyourPHOTOS@reddit
We leave them open all summer except in the summer we close them up and close up the shades in the AM until the temp outside is lower than the temp inside. We open them all in the evening and leave them open.
AbiWil1996@reddit
Yes, I “air” out my house every morning before it gets too hot. Sometimes during the winter time before the bugs come out but it’s still not that cold where I am, I open the patio doors as well (can’t try that during the spring or summer or a million wasps & mosquitos would enter)
Lucky_Ad2801@reddit
I only open mine if air pollution is low enough.If there air quality is bad, they stay shut because the air is actually better indoors.
Still_a_skeptic@reddit
Nice isn’t super common. The wind doesn’t fuck around here.
BasdenChris@reddit
Our weather in the northern Great Plains is chaotic enough that, at least in our house, we pretty much go from heat to A/C without much (or sometimes any) time in between. This last week, we’ve hade days with lows in the teens (Fahrenheit) and highs in the 20s to days with lows in the 40s and highs in the 70s. On those nice days I’ve opened a window to cool the bedroom down, but the variance is too wide to leave a window open all day.
If we do get a week of consistent 50s Lows/70s Highs I’ll open a couple windows and leave them open, but more likely we’ll go from this weird roller coaster of temps to the hot part of the season where I can’t sleep without the AC.
Girlwithnoprez@reddit
I grew up in a house where our windows were open 95% of the time. We had Central Air but my Dad was weird about "Fresh" Air
Prof-Bit-Wrangler@reddit
We have our windows open as often as possible, hell, even in the middle of winter we'll keep one or two cracked for fresh air.
Early spring to about June is our favorite time. Cool nights make for wonderful sleeping weather (except the pollen).
Hate the summer becuase of needing to run the AC.
CycadelicSparkles@reddit
I turn on my air conditioner (I have a single window unit in my bedroom) when it's too hot to sleep even with the windows open.
awfulcrowded117@reddit
I open my windows in the early spring, but I don't tolerate heat well so my AC goes in the window pretty quickly. The windows being open just isn't enough for me to be remotely comfortable, and I'm not gonna sweat in my own house to save on my electrical bill.
2-Ns@reddit
Yes, I love having the windows open. The problem is the nicest spring weather coincides with Pollen Season where I live, and so there are 2-3 weeks where the thermometer says Open Window Season but my nose says Never Breathe Fresh Air Again.
donutsnail@reddit
I do about the same as you. I think most people though prefer the consistency of letting central a/c maintain one temperature rather than having the house fluctuate so much between night and day
Markca8688@reddit
Pollen can be horrendous where I live. I keep windows closed.
ima_mandolin@reddit
I keep mine open as much as possible. I switch to AC once it's in the mid 80s and humid.
ApprehensiveSkill573@reddit
Yes, when the weather is nice, I open the windows. When the weather is too hot, I close them and use the air conditioning.
Spackleberry@reddit
I do. Where I live we can have windows open during Goldilocks periods in April and September before it gets too hot or too cold.
arcteryx17@reddit
Depends on humidity. When my house hits 74 degrees I typically put the AC on if its humid outside. If its dry I will.wait until the house hits 78 degrees until I put the AC on.
Xyzzydude@reddit
Yes whenever I can. I close the windows and turn on A/C when the pollen is in full swing and/or the humidity starts to soar (I’m in NC).
Also close them if my neighbors are using loud lawn equipment, especially gas powered leaf blowers.
NaomiiiTwinz@reddit
It's very hot in South Carolina, so I only open the window when it's cool outside even if the weather is nice, it's just too warm for me.
Other than that, we keep the AC on throughout the day.
IsopodKey2040@reddit
Yes, we open our windows. My windows are currently open. I close them and turn on the AC when it feels too hot, idk lol.
