CM Heating

Hired CM Heating for a routine furnace tune-up. The tech first told me my heat exchanger was cracked and there was rust. After I called their office, he changed it to: no crack, just a little rust — and the rust isn't a problem. But his meter was showing CO, he couldn't say why, and his answer was to replace the… Read full review

CM Heating techs Michael M. and Joseph M. arrived on time. They figured out the best way to reroute the PVC line so the water could drain without a condensation pump. The original setup with the condensation pump created an odd sound whenever the pump stopped running. Michael felt that there was an issue within the… Read full review

A plumber is now required to service tankless water-heaters. So the plumber came to clean my tankless, which has never had problems in the 13 years I've had it. Now water is dripping from it and I will have a lot of repair work to do on the floor. Now I need a plumber to fix what the first plumber broke. They used… Read full review

CM is awesome!

They did the annual maintenance service. All of my questions were answered and the system checked out great. Happy with the service. The guys were as usual very courteous.

Very nice but didn't change the filter as it was not standard...but never told me they didn't change it. Only after I called did they say it would cost extra to change a non-standard filter so I purchased and they're coming back to change it. Seems odd.

Already did survey, wanted to let management know Tyler is the Best. Great understanding of the task at hand. quick to point out issues. Easy to work with and a true professional. Job 1 attitude.

Anderson was on time, friendly, respectful of my property, and very knowledgeable. He didn’t push any other services or products and left the decision solely in my hands.

Very efficient and very fast.

Always a good experience with this company. Luke did a great job and was very pleasant to have in our home. Another year with CM Heating - this time Doug Jansen.

Perfect

Friendly and professional. Helpful.

Excellent service! Technician was on time, polite and efficient Such a nice, considerate guy!

Graham Brown did an excellent job inspecting HVAC system. He was professional, did a thorough job and answered my questions and explained what he did.

A++ for Adam. I learned about temperature control in the house for my AC and Heating. He is professional, personable, and extremely knowledgeable about all AC and heating. CM Heating is fortunate to have such a great employee. Give that man a raise! But if you have to raise my monthly rate to do so, I’d like to rethink that. Lol. :-)

Thorough and reliable service.
