They won't be the cheapest but I absolutely love Baker Brothers for both plumbing & HVAC. Not only are they always there when they say they will be, they always have like one or two alternatives if the repair is too expensive. They've come out as an emergency next day 8am service & there was no extra charge even though we called them at like 11pm the night before.

Even their dispatch is next level, always making sure they have the details shared with the people doing the repairs & maintaining contact for anything scheduling. They'll send you an email or text when the tech is on their way with GPS so you can see exactly when they'll arrive. They have photos & descriptions for every tech so you know who is going to be showing up at your door.

When something broke on our water heater the tech told us what it was & asked if we wanted to go get the part from Home Depot because it would be way cheaper but we were literally going out of town that evening & didn't have time, so he did the fix & then gave us info on what part it was in case we needed to ever buy it again.

I cannot say enough good things about them.
