Comfort First Heating & Cooling is good. They were on time and did what they said they were gonna do! The cost was not bad either. It's pretty easy to schedule an appointment if I need them to come out. I have a service agreement with them. We purchased a central heating and AC unit from them with a 1 year service warranty. They do a good job so all I would say is keep up with what they have been doing so far. I would definitely recommend their service.
