CM Heating

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.

Been using CM heating for 17yrs. I recommend them. Great people.

I've been with Cm Heading for a long time will not go anywhere else. They have taken care of my family's needs. They make everything right all the time.

Very detailed and thorough. And also a nice guy.

Our tech, Anderson Carter was wonderful. He explained how well our system was working and how we can improve the life of the system. He was extremely helpful, personable, kind. Would love to see him stay with the company and be our tech with any issues we might have in the future.

Anderson Carter is stellar

Ray was a pleasure to deal with. He did a very thorough job and gave us some new information about our system. We've always been happy in our dealings with CM Heating.

Caleb was friendly and professional in the maintenance of my air conditioner. CM Heating communicated with me regularly to make sure I remembered my appointment and who would be coming to my home.

Dan came out to my house to check on my AC unit that wasn't working. No cold air on a 90 degree day. He came that same day, assessed the issue, and let me know my options going forward. He was very professional and very nice to deal with. Great job, Dan!

This gentleman was thorough & fast. We appreciate his help and highly recommend him.

6/10/2026 - Graham did a great job servicing our mini split and was very professional. 6/11/2026 - Josh found a hidden electrical panel in our garage last week. The power went out and he couldn't figure out where the wires were coming from. The panel he found was a Federal Pacific panel and was recalled. He cleaned… Read full review

Edgar was very pleasant and professional. I had several concerns and requests which he assured me he could take care of. One company said I needed to replace my electrical panel if I added a heat pump. Edgar shared how I could save money by not replacing it. I appreciate his honesty!

Chase Bolen was very knowledgeable, personable, and honest. He took the time to explain things clearly, answered questions honestly, and made my experience a positive one. He's the kind of technician who makes you want to stay loyal to a company. Thank you sir!

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

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. :-)

Annual maintenance very thorough. Used many instruments to check all details. Very satisfied with the routine maintenance visit.

Friendly service, tech helpful and professional, great suggestions, very efficient and kept me informed throughout the service

Working with CM Heating has been incredibly easy! We were giving a lot of great information to help us make our AC decisions. I appreciate that the company gives me information about who is showing up at my house and that they text when they're on their way to your house.

Technician was knowledgeable, efficient and personable. Great representative of your company.

Graham and Carter were polite and friendly. They did a complete test of our thermostat, furnace and heat pump. Highly recommend!

Edgar was great to work with, very knowledgeable and professional! I’ve been going with CM heating for everything from our fireplace maintenance to electrical and getting our EV charger installed now, I have always had a great experience with them!

He did a great job at explaining everything and was very professional. Very nice and friendly.

We love CM Heating... they are very professional, thorough and friendly! Would recommend them to everyone.

Another great service call with CM Heating. Enjoyed Jacks company he was friendly, thorough and considerate with great conversation. .

Austin was courteous, friendly, and efficient! He checked out all of the parts and made sure everything is working properly.

Brandon did a great job when he came back out today and did the cleaning right that it needed

A very competent and friendly representative

Louie, was very professional and kind. He was respectful and used shoe coverings in the house. He was very polite and gave me thorough explanations when I had questions about my heat pump. Thank you!

Cody was alright. I had to mention to ask if he was going to clean the filters cause he started putting him back in. He said they weren't that dirty but thats part of maintenance. Otherwise he did fine

We've worked with CM heating for several years. They've installed a heat pump and furnace for us, and do our yearly maintenance. They've always been very professional and quick to respond when we've had issues.

Update 12/8/2025 For some reason they thought I had a heat pump when I have a gas furnace and separate AC unit that they installed (both of them). So the servicing guy could only do the furnace and they'll need to come back in the spring for the AC. They had the same data issue earlier this year and I corrected… Read full review

I waited to write this review because I wanted to see whether they were not only good at installation but also responsive when issues came up. After more than a year, I can say they’ve been excellent, professional, quick to answer calls, and super easy to reach!! Highly recommending them.

Graham did a great job! Very thorough and informative!

This was the third repairman (maybe fourth - lost track) to fix our “gurgling” sound on our AC unit. Fixed it in record time as it turned out to be a simple issue of gravity. Many thanks for the fix, the absolute positive nature and demeanor which personified his pleasantness. Very nice gentleman AND HE WAS… Read full review

I had our electric furnace and heat pump serviced by CM today and I was really impressed with them. Zachary came out and was really nice and knowledgeable and did a really thorough job of inspecting the system and both units. There was one repair that he suggested and he explained everything really well and showed… Read full review

During the inspection the technicians identified that the A/C unit was very much overdue for a deep cleaning. They were able to pivot and include that cleaning as part of the maintenance visit with a reasonable increase in price and time to complete.

,Hagen Tidwell of CM Heating arrived on time and was in a clean uniform and presented himself very well. He was there for A/C and heating maintenance . He was quick and efficient in his job. I will used them for yearly check-ups and more. The company does Duct cleaning, plumbing and electrical!!
