Dak Jones is an amazing air tech. He looked at our problem identified the issue and quickly fixed our drain problem on our unit. He was very conscious about the mess and cleaned everything up he could. He was very polite and courteous.There are not many companies that have employees like this in service. I definitely recommend Cornerstone Air and will be using them again.
Linda BarnesExcellent customer service and quality work.
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!
Clayton at Cornerstone did a wonderful job getting my air conditioning units clean, and up and running again. He was honest, and let me know that my main problem was the setting on the “smart thermostat” ecobee was not correct. He also did an excellent job explaining to me everything I needed to know about my 2 units, and their current working condition. In today’s world where big contractor companies dominate the market, it’s hard to find people that you can reliably trust to get quality work and honest work prices. I give this company my highest recommendation. I would suggest you give them a try.
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!
