Call called of Cornett heating & cooling in the morning due to a air conditioner pumping out warm air. They were able to service me immediately that afternoon and solve the problem in less than 30 minutes. Technician was friendly and courteous and explained everything. Definitely will use again.

Danny from Cornett was on time and worked efficiently to troubleshoot my multi-zone ductless system. He was courteous and respectful while at my house. When he was done, my AC was working and he cleaned up so well that you'd never know he was there. I'm very happy with the service I received.

I was so impressed with this company. Our AC went out and Julie went above and beyond to help insure my AC was back up and running as soon as possible. Fast service, very professional and so helpful. I would absolutely recommend this company 100 percent.

Called at 9am and was told someone would be out at 1pm. Then received a call shortly after that they were in route. Great service. Robbie diagnosed the issue immediately and we were back up and running within 20 minutes. Josh and his crew are the best.
