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.

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.

The technician was On time, knowledgeable and friendly. I’ve used CM for years and I always get good service.

This was to be a routine exam of our Rheem furnace. Charles, the technician, was on time, friendly and proficient. The part that was replaced was pricey but he didn't pressure me and he gave me some alternatives. The receptionists in the office were equally friendly and helpful. I'll call them the next time for routine maintenance or repairs.

CM heating was very responsive when our heat went out. Younis and Mazen returned and was able to fix the problem (need to order the part). CM heating has done other work for us and they are always professional, reliable, knowledgable and courteous just as Younis and Maxen was today! I would recommend them to anyone!

Austin @ CM Heating did a great job cleaning my mini split. It's running a lot quieter now.

Great, prompt service! Scheduling was easy. Carter did a great job diagnosing the problem, explaining the fix and getting everything up and running. Thanks!

Steven did a very thorough job of with maintenance on the 2 units we have. We have a membership so I was very happy.

Carter Middleton came at 9:30pm to hook my heat back up after the first technition forgot to hook something back up, causing me to have no heat. He also changed the filter which the other young man didn’t do even though the appointment was for yearly maintenance. So “thank you Carlson Middleton for a cheerful attitude and the extra effort”.

CM Heating is a great service provider. Few days ago, a technician by name Younis Abdel-Kader had come for electric furnace maintenance. We are very happy with the service.

Great experience. The guys were courteous, answered my questions and seemed to do a good job. I say seemed because I am not an hvac expert. However, I ask questions and can spot bs and I was pleased with this service.

Very quick resolution to the issue.

I cannot say enough good things about the service I received from Zachary McMurphy at CM Heating. Zach stepped in at the end of the day after another technician’s visit fell short, and the difference in professionalism and workmanship was immediately clear. He took full ownership of the situation and when he wasn’t… Read full review

Hagan is easily the best we’ve had over here. Diagnoses a challenging issue immediately. Thank you!

Emmanuel did a great job with my annual service. He made sure everything was working properly, he was careful and washed/cleaned up my outside unit. He also was very personable and professional.

Our tech was very good, informative and timely. Ive been using cm for many years and theyve always been good.

Brandon Ainsley- Thank you for a fantastic maintenance and repair on our gas furnace. We will definitely have CM out next year for the annual maintenance visit. 😊
