Danny did a great job diagnosing the problem with our heating system. He was very thorough and explained what he was doing. After determining that our thermostat was bad, he replaced it with a thermostat that we had previously installed. He was very professional. I highly recommend Cornett Heating and Air Conditioning.

Cornett has come to us 3 times and each time the technician has been professional, knowledgeable and kind. He has also been early! He informed us of our choices and didn’t try to sell us products, just educate us, which was extremely helpful and makes us want to use them when we do upgrade. We will definitely be using them in the future.
