First time using C&M, and they are knowledgeable, helpful, and willing to educate. I learned things today about my geothermal systems that I should have known a long time ago. Daniel went above and beyond to get us back to running smoothly again. Great job!
I've called C&M for 14 years, since they fixed a previous company's poor calibration. They always show up on time for a fair price. Most recently, they had someone out in less than 24 hours even during a deep freeze spell in the middle of winter. It was an easy fix, but regardless, they know...
I've called C&M for 14 years, since they fixed a previous company's poor calibration. They always show up on time for a fair price. Most recently, they had someone out in less than 24 hours even during a deep freeze spell in the middle of winter. It was an easy fix, but regardless, they know their stuff and they've helped me keep what's now a 16 year old heat pump running efficiently and smoothly.

Couldn't be more pleased with service by C & M. Their rep, Justin Hutcherson is a delight to work with. Reasonable priced.

I don't know if Daniel fixed our problem or not with our hvac system (he just left and I won't know probably till tomorrow whether the solution fixed the problem)...but even if he didn't fix the problem, he spent so much time and effort that I want to leave a good review now. He was diligent with troubleshooting and patient and listened to the unusual problems we are having. Thank you Daniel.

After a different company said we needed to replace our 8 year old HVAC system because a part was unavailable, we called C&M who came out and repaired it quickly and efficiently with a part he carried on his truck. I can’t say enough about their speed, service and integrity. A big thank you to...

I can’t say enough about their speed, service and integrity. A big thank you to our tech, Justin!

They were very easy to work with, got scheduled right away when my HVAC was having issues. Timely and thorough work and a fair price.
