This is the ONLY company I call for AC repairs! I know whatever issue it is, Chase and his team will have it diagnosed and fixed without price gouging. So happy to see the company grow over the years and it just goes to show, honesty and integrity DO pay off in business!
I had a great experience with this CM from start to finish. They were quick to respond, showed up on time, and diagnosed the issue right away. The technicians were professional, knowledgeable, and took the time to clearly explain what was wrong and what needed to be repaired!

We had a new DAIKIN AC condenser unit and air handler installed (removed old one down from attic and replaced in garage). They also had to add a few pieces of new ductwork. Their team arrived promptly at 8 AM and worked into the evening hours so that we would have AC comfort for sleeping. They were promptly back the next AM to finish any remaining work and clean up. They were very diligent in making sure everything was well sealed for air leaks on the air handlers and in the attic ductwork. Their team seemed very knowledgeable and were very polite and knowledgeable. As of now, we highly recommend CM AIR for AC replacement and maintenance.

I recommend CM Air to all my friends. They are an honest and fair company. They were able to help me out with and fix my system in a day. Thanks so much!
I had an issue with my meatcase at my business and the tech came quickly and fixed the problem. Very efficient. Highly recommend. Good pricing.
After a botched and priced gouged job from a different “5 star highly reviewed” HVAC company I was in dire straits. Chase and Ed came in to fix rare and complicated issue and install requiring a new system and 150ft of all new piping. They worked 9am-11pm just to get my AC back going after...
