I cannot express enough the help and professionalism we received during a very stressful time. John was extremely helpful from the moment he took my call, he did everything to help trouble shoot, showed up in booties, made calls to his supervisor and never let off the gas, we had a severe leak, mold and he took his time trying to help us with the best possible option to reroute a condensation line. We have 4 vendors in and out of the week trying to identify the problem, I’m so so grateful for making the call to Cornerstone!

Cornerstone Heating and Cooling recently came to my house for an AC issue, that included a leak affecting my neighbor's unit. They responded quickly, communicated clearly, and sent someone out a couple times to make sure everything was fixed right. They were professional, reliable, and easy to work with. If you need to have your HVAC system serviced, give them a call!!
