Mitchell's One Hour Heating & Air Conditioning is definitely a "Five Star" company! Their service is great, and their employees are very nice people. They came out most recently to clean my furnace and to work on a problem I was having with it. It kept cutting on and off. They winterized everything and checked out the whole system. They gave me some suggestions about things I should be thinking about. I have been really impressed by how they always seem to know what they are talking about. And, that they always solve the problem! I highly recommend Mitchell's!
