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!

Clayton and Dak helped me out big time! Had a condensation problem and they showed up and got me fixed up in a very quick time frame!
Chase & Samantha Mullino

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.
Craig Scoggins

Clayton and his team were great. We had a 20 year old system go out and they were able to get a new system installed the next day in the middle of summer. Fair on price and great service. Highly recommend.
Brad Robinson
