Everything was quick and professional. He explained everything clearly and was very helpful. Response time from our call to having our AC working again was only a couple of hours

Fantastic service!! Our A/C went out in the middle of a heat wave...heat index over 100F! We called Cornerstone Air and requested an emergency call from their answering service. Clayton called us back within minutes and arrived at the house less than two hours later. He assessed the system, found the fault, and fixed it in about 15 minutes. A great experience from start to finish without having to fight our way through AI bots like with other companies. HIGHLY RECOMMEND!!
