This was my first experience with Stay Cool and I’m very pleased. Dalton installed a new humidifier and performed a spring maintenance checkup on a neglected air conditioner. He was prompt, professional, courteous and had the parts necessary for the identified repairs. I highly recommend.

Furnace decided it was unhappy with the quick shift back to winter temps, and gave no heat. I scheduled an appointment online, and within 2hr Travis arrived. Problem part was quickly identified and replaced getting heat flowing again. Very impressed with their response and service overall. Great job!
