I have used Comfort First Heating & Cooling twice now. The last time they came out because I had a problem with my heater. The technician that came was very friendly and professional. He took the time to explain things to me. I was very happy with the guy, he fixed the problem with the heat and he was very knowledgeable. They have very fair prices. I even signed up for the maintenance contract where they come out annually and do the tune-up on my units. I would definitely recommend this company to other people.
