On time, nice person, clean, and not condescending in 2018 I still get men who talk to me like I am a stupid woman homeowner, car owner, human body owner, etc. when I ask questions!! I know a lot, but I don't know the technicians job. If I did know their job, they wouldn't have one!)
Anyway, fair price, good work, and it's still working, I'm happy and I will call them again- gave their name to my neighbor for their friend's heating and air-conditioning needs.
