Keystone Climate Control LLC

Sean has been taking care of my HVAC system for some years, he is a very dependable, honest and helpful professional! He saved us in the middle of this freezing cold and worked until very late to get the job done. He has a very positive track record with me and I keep referring him to friends and everyone is always happy with him. Definitely recommend!

Outstanding service! Keystone went above and beyond, coming out in the snow and walking down our very steep driveway (in the snow) without hesitation. The technicians were professional, reliable, and clearly dedicated to helping us stay warm. Their commitment, even in tough weather, truly impressed us. Excellent workmanship, great attitude, and top-notch customer care. They even brought down a UPS package we had at the top of the driveway! Highly recommend!

Sean and Raphael were great. They were able to schedule my service right away and on time as usual. Company is top notch and super courteous as well.

Highly recommend Keystone Climate Control! They recently installed a Daikin mini-split air conditioner and heat pump in my home, and I couldn’t be happier with the results. The quote was fair and competitive, and the entire installation process was smooth, professional, and completed on time. Thanks to their work, the comfort level in my home has significantly improved. I’d gladly recommend them to family and friends.

Sean and Co. have been fantastic. The operation is professionally run and they have done an outstanding job of diagnosing and resolving some long term issues.
