Testimonials

Cornerstone was quick to respond and diagnose the issue. With it being the hottest day of the year and our A/C broken, I could not have been more thankful. Clayton was knowledgeable and professional and I will definitely call them in the future when the need arises.

We had such a great experience with Cornerstone Air today! We had the opportunity to meet Dak Jones, the founder. He was very friendly, professional, on time and thorough. We also admired the fact that he was very honest with us. We are in the process of selling our home in Frisco and we just wanted to have a peace of mind that everything was operating properly and Dak definitely put our minds at ease! We will definitely use Cornerstone Air again for our new home! Thank you Dak and to his team!

They came out same day when no one else would and fixed my AC quick. Great service would definitely use again!

Clayton and the team at Cornerstone Air did a tremendous job for us when one of our old AC units froze up and was leaking. Clayton came out the same day and assessed the situation. Although the news wasn’t great, and we were going to need a new unit, he took the time to explain and provide options and recommendations. He also checked on our second unit and determined that it was working well. While on-site, he called his supplier and verified the pricing/availability, and we scheduled an appointment for installation. Clayton kept us up to date with the status and had his team out for installation exactly as scheduled. As it had been raining earlier, they were courteous to keep all work areas clean and used a hand truck when they were replacing the outdoor unit so as to not leave ruts in the yard. I highly recommend Cornerstone Air as a company you can trust to be honest, fair, and do excellent work.

Clay and the crew were incredible. They gave first class service and we highly recommend them to anyone needing air-conditioning services.

Great experience. I wouldn’t hesitate to hire them again.
