Josh leads a team of true professionals who are extremely knowledgeable. He even went above and beyond and came over after hours to service my heating unit on short notice. I would highly recommend Cornett Heating & Cooling.

Great guys. Was right on time. Listened to me for what i had already done to the unit before deciding it was time to turn to professionals. They promptly got to work. Then brought me to the unit and explained to me what the problem was, which part it was, and why it failed. Will continue to use this company in the future.
