I had Gremillion Mechanical out to fix my furnace after it broke this winter. I spoke with Brett on the phone to schedule the appointment. To my surprise when the service technition came to fix the furnace, it was Brett. I later understood that Brett was the owner and did a lot of the work himself. I felt this to be a great factor in the repair because I was not put through ten people to get one job fixed. When he came out and figured out the problem, and did it very quick, he explained it to me in great detail. It was very comforting that he helped me so quickly and did not have to leave my family cold for the night. Also, the rates were less then everyone else and when I called for other quotes all the other companies woud not even come out the same day. Best heating and air conditioning company for me and all my friends from now on. Highly recommended.
