Recently had a AC unit go out and Cornerstone had it handled from diagnostic to new unit installed in 24 hours after a failed attempt from a previous provider. Experience, Expertise and handling your business matters. Dak and his team crushed this project and provided great value on the new unit as well..

Thank you for fixing my AC issues so quickly and efficiently! I appreciate being given options on how to repair the unit and a thorough explanation of the pros and cons of each option. It’s great to know you are a company I can trust to be honest and not just do what is best for your wallet! Great service, professional crew and job well done!

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.

Have never had such a quick response in service and taking great care of the A/C issue. Clayton T. was great to work with on this call. Their service is top notch and experience is as well.

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.

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.
