I will give them A+ and will definitely use their service again and recommend them to my friends. My AC compressor didn't start. I called two different companies to check the problem before calling Coleman-Mitchell. Both the other 2 guys told me that I need a new compressor or an entire new system, which cost me ranging from $2,000 to 3500. I called different companies to get some quotes. C-M came back with the best price, so I decided to go with them. Matt, the technician, spoke with me before arrival. He said he would run some test and make sure if I need a new compressor. Guess what, he fixed AC within an hour. Matt just saved me $1,500. Thank you so much, Matt. C-M offers very good service and best price (trust me, I called 10 different companies to get quote for replacing compressor). I really appreciate their professionalism and honesty. Again, thank you Matt and Coleman and Mitchell.
