Approved Comfort has been my HVAC company since 2006. Every year they come out to do the annual maintenance on my furnace and air conditioner, and on occasions they have come out when my furnace or air conditioner have been out, like was the case last month. I called them out because I was having problems with my furnace, they quoted me to repair it but it made more sense to have it replaced, so I decided to have both my furnace and air conditioner replaced. As soon as I made up my mind they scheduled my installation. The installer explained and showed me everything about the furnace and they will be coming back in the spring to start up my air conditioner. He was also very helpful on the things that I will need to do for future maintenance in order to keep my warranty intact.
