I was planning a heater upgrade and received a 24 month no interest offer from Home Depot. They sent me a list of contractors and Comfort Air was the only contractor that called me before I could call anyone else. The customer support, salesperson and installers were fast, competent and incredibly supportive. From the time that I contacted them until the heater was installed was fast and the new heater is a big improvement over what I had before. Highly recommend Comfort Air for fast, efficient and professional service. I feel comfortable that they will be responsive, should there ever be an issue with my new heater!
