Can’t say enough about the great experience we had with Stay Cool! Skylar and Trey completed a system removal and new system install for us. Great workmanship and care taken. They were both respectful, kind and professional! Highly recommend Stay Cool for all your HVAC needs! They make the whole process easy. Also want to thank Travis for his diagnosis of our 18 year old system and making it operational for a few days.

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!
