Stay Cool Air Conditioning Heating 5 Star Customer Service Icons badge
Anthony was a great repairman. He was courteous and knowledgeable. The office said he would be there next day, but expedited the call when she found out our house was warm and uncomfortable. I need a new unit and will use them in the future. I notified my neighbors and several said they would call them next time their A/C needed repairs. They all were great with outstanding customer service.
