5/5
Contacted regarding HVAC and thermostat not working. Same day emergency service which I didn’t expect. Technician quickly and thoroughly diagnosed the issue and recommended a repair which unfortunately was a new control board. Scheduled the repair, installed, and checked the system to make sure it was working. Overall great service for an unfortunate breakdown.

Our AC started blowing hot air. The tech was available within an hour and thoroughly tested my system. The honesty and clear information potentially saved me a lot of money. The repair was a loose wire. Now we have functioning AC going into the weekend. Highly recommended! Thanks Cornett!
