J. got my water heater pilot light going again. It was quick and easy. I maybe could've done it myself, but I am physically challenged. It's good to have affordable help, sometimes!

Our ac went out the week before Thanksgiving and we were so stressed out. Stay cool was fast to get someone out for a quote. They were straight forward and upfront about everything. The unit had to be replaced and the one we picked was installed quickly and professionally.

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.
