Danny from Cornett came out promptly when he heard our AC was down and we had a newborn in the house. Made sure that we had a solution to keep us running while new parts were ordered and got us all set back up super quick. Couldn't ask for better service from Cornett and Danny!

Cornett Heating and Cooling was extremely responsive. I contacted the company, spoke with Julie and she quickly and politely scheduled my appointment. Tech (Zach) came out diagnosed the situation, found some wires had been damaged. Ran new wiring and had my A/C back up and running in less than an hour. I am very satisfied with this companies work from beginning to end. I highly recommend this business. Thank you, Cornett and Team!
