I recently hired Keystone to repair our walk in cooler that had suddenly stopped working and I couldn’t be happier with the results. Eric was fast and efficient with his time. I would highly recommend them to anyone needing HVAC services.

I had a crazy knocking sound in my vents & Jared never gave up tracking the problem down. 2 days and lungs probably full of attic insulation - he annihilated that pesky problem. Plus, he found a safety hazard with my furnace flu and set it up right (something my home inspector missed.) Keystone has a happy and loyal customer in me.

Had a great experience with keystone, they are so great and honest about what needs to be done. They have really great pricing and so easy to get in touch with and unbeatable prices. We got a new ac unit and they made everything easy to install and they offer financing if you cannot afford a new one which is so great. Cannot recommend them enough!

I highly recommend Keystone heating and air. Our AC was not working and freezing up, mid July is a terrible time to lose AC. Keystone responded so quickly and was to my house by 11am. They quickly and honestly identified a problem, fixed it and had us cool and happy again by that afternoon. I am grateful they were so honest and thorough and gave great recommendations on how to improve and maximize the performance of our unit. We will use them anytime we need help. Thank you Eric!

Very quick response and reasonably priced

Keystone was recommended to us by a friend. They came out same day and fixed our unit! Couldn’t be happier before a heat wave!
