We just had Samir, Mark, Michael and John out to replace the water heater and install a GFCI outlet, they made sure to take care of us the same way the HVAC team did back in January. They wore booties, drop cloth on our floors, were so quick and efficient with their installation and did a bit of troubleshooting…
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…
UPDATE: This was the quickest 1⭐️ to 5⭐️ switch! Aaron reached out immediately to understand the issue and provide a resolution wherein Charles was able to swing by and fix the issue within hours. Aaron also acknowledged that they would ensure that something like this would be resolved much more seamlessly going…
Emmanuel Maldonado, clean, courteous, respectful and thorough. Exceeded expectations.
It's hot. The tech did come out the day after I called.. I don't know how or when my cooling coil will be replaced do to the one installed 30 months ago leaks. I do know they plan to charge 1200.00 whenever the figure out how to get a part that's no longer made. They said if they don't call by tomorrow then I should…
Excellent, quality work!
Had 3 yr. Old system annual check-up !! (HVAC & Furnace)
C&M Heating and Cooling just completed another annual check-up of our Heat Pump system. James Penney, a friendly professional, completed a thorough examination, spending more than two hours with detailed attention. We have been very satisfied with C&M since they installed our heat pump in 2022. James Penney is…
Dan did a good job checking out the system and, especially, explaining the possible causes of ice build-up and preventative steps to avoid in future. On follow-up visit Dan did an excellent job of isolating the refrigerant leak to the inside unit coil and initiating the warranty-covered order for a replacement…
He did a great job!
Great crew, very efficient and knew their business! Never left a mess, cleaned up after every phase and at the end of the day.
Detail oriented , clean and friendly.
Great service
Got it done quickly
They were great. Here on time and got the job done right.
Great communicator. Timely and solved the issue quickly. Highly recommend.
Edgar was so well prepared and knowledgeable about the electrical work needed - took time to explain and really listen to us. A true professional and frankly just a great guy. Couldn’t recommend higher! - Greg
The tech was very helpful and knowledgeable, he has locked my business. Thank you
On time, clear communication, glad to be in the club.
Came the same day, for an emergency fixed price, then charged for the small fix. He fixed my problem and was quick. Would use them again!
Hagen is great. Very knowledgeable and he taught an old electrician a lot more about how these systems function. Looking forward to next visit to clear up the issues we encountered.
Dan was very helpful in getting our system running again. Explained how the system worked and what we needed to do to keep it running smoothly.
Our AC went out right as the hot weather arrived. Thankfully, CM was able to come out the same day I called. The technician quickly diagnosed the problem—a failed capacitor—and had the replacement part stocked on the truck. Within 30 minutes, our system was back up and cooling again. I also appreciated that the…
Excellent service
Simply outstanding, professional service by Nikko Cossins who is an extremely well trained technician who performed a masterful maintenance service. I would recommend this company to anyone needing HVAC service. Thank you for another outstanding job.
He showed up on time, completed the job and cleaned up.
Dan was prompt, professional and kind. He fixed our system on the hottest day of the year without delay. I would recommend CM to everyone
Hagen was friendly and worked quickly.
Amazing experience! Diagnosed and fixed all my issues. Highly trained on all systems!
Adam was very knowledgeable and friendly. Solved the problem immediately. Thank you!
Charles was awesome. Informative, approachable, and engaged. I would be happy to have him as my permanent CM tech.
I've never had a company communicate so well. The job was finished quickly and efficiently. No one was in the home at the time, but communication by email and text with pictures was very helpful.
Outstanding 👍
CM Heating did a maintenance call on my heat pump / air conditioning unit. On time thorough inspection and cleaning. Doug answered all questions and gave me advice on my systems. Well done
06/15/26 Emmanuel did n incredible job, friendly, efficient and we are claiming him as our tech from now on.
Dan really took the time to troubleshoot our AC and got it working. He also set us up with a followup plan to make sure the same issue does not happen again.
Emmanuel and CM Heating LLC were great with a same day appoint and a quick solution that saved us on a super hot day. What a relief. Thank you! The price included an annual maintenance arrangement. Good value.
CM Heating was quick to dispatch someone for an AC repair on a Sunday and Dan even arrived early. He took the time to answer all of our questions and went above and beyond to get us back online with our AC unit.
my problem and explained what was going on was fixed fast
Quick appointments, solid expertise and a fast solution to my heat pump problem. Thanks, CM!
Excellent customer service and very knowledgeable. Highly recommend CM!
Jack served me well, on time, well prepared and no surprises.
CM Heating came out, found the issue, and fixed it promptly. Very happy. And now I'm signed up for regular maintenance with them.
C & M Heating did an outstanding job servicing our furnace. Our technician was thorough and knowledgeable about everything that needed to be done. I highly recommend C & M Heating! Roger Montgomery
This is the time we have used CM. The company we used in the past was not properly trained or responsive. Elliot Bryce with CM did a great job troubleshooting and addressing issues we have been having since the unit was installed by another company several years ago. He also spent the time to explain what he found, and how and why it was being addressed.
HVAC system not responding to thermostat
Our heat pump stopped working. I called CM Heating and they sent a technician out the same day. Our unit is not one they carry, but Adam was able to diagnose our problem and proposed a couple of solutions. He checked on our warranty and determined that we should have coverage for the part. He ordered the part and…
Hagen Tidwell was prompt and provided a thorough inspection in trouble shooting the thermostat issue. Friendly and kept me informed as he checked the HVAC, furnace and the control pad. Lennox thermostat went out and costly to replace. No reflection on CM Heating they are great. But Lennox is no longer on my…
Hagan was very professional and straight forward. I would call again.
Great experience with Brandon Ainsley! Came in and diagnosed the problem right away and did a great job.
Excellent service! Great techs! Scott was very professional and thorough.
Thorough, polite, and very knowledgeable. Would recommend and use again.

Very satisfied with the service provided by CM Heating in repairing my furnace. Amy was very helpful in setting the appointment, giving me all the details I needed in a professional and courteous manner. Antonio was the service rep who arrived as promised, listened to my description of the issue and had the proper…
Joseph Marich did a great job. He was very professional and knew what he was doing. We are very pleased with the service.
Fast, friendly service! Adam from CM Heating arrived on time, quickly found and repaired the issue, and was fun to talk with as well. Thanks so much!
Great service from Hagen! Unfortunately, we were not able to solve the problem today, but he was super clear with what was going on, did a thorough investigation to find all the issues and assured me that they would be able to resolve the problem with the external temp sensor and refrigerant soon. Hopefully we can…
Needed to replace a 25 year old heat pump that recently ceased functioning. I called CM and within 24 hours their representative Javierre was at our home to assess our needs and offer options. He was very knowledgeable and answered all our questions. We felt very comfortable discussing them with him and confident…
Samir was great and easy to work with. No pressure and willing to answer any questions quickly without making me feel ignorant!
Punctual and professional as always, they tested my heat pump and gave me quotes right away. Friendly service
The technician was very professional and performed a thorough maintenance of my heat pump. I was able to get the appointment fairly quickly and everyone I dealt with was pleasant to talk to. I could not be more pleased from the customer service side of things. My only complaint is that I was charged $220 for a $10…
Adam was very knowledgeable and professional. He worked until he fully fixed our Heat pump. Just in time for upcoming warmer weather 😎!
Great job! Very knowledgeable.
Our furnace was responding to the thermostat a bit erratically, so CM sent Brandon (who had performed admirable service back in February of this year) to set it right. Once again, we are very pleased at CM's quick response and high-quality, personable service personnel like Brandon. 04/24/2026 Caleb performed…
Brandon was very thorough and professional
Spencer was amazing!! He is very personable and offers a wealth of HVAC knowledge. He and Remis were meticulous with the install and double checked to make sure everything was working properly. The finished encasement work is sleek and customized for our home. Top notch work--highest marks!! James
Prompt and professional.
I just moved in . Furnace and heat pump needed service. Doug, ¹ CM technician, very polite and fully explained all he did and why.
Very professional and friendly!
All went well. The guys were polite and seem to spend quite a bit of time making sure they checked everything.
Knowledgeable in the hvac system. He is polite & friendly. He doesn’t talk down to you like mose specialty services do. I highly recommend him & cm heating! Great company & fast service!!
Doug had a great personality and was very approachable. Answered many questions and was very helpful. The guys was professional throughout.
Great job
Had an excellent experience with Hagen and his apprentice. They identified the gas leak in my furnace and fixed it quickly while teaching me about some of the important elements of my furnace. I strongly recommend CM Heating to anyone who needs help with their furnace (or even a regular maintenance check!).
Quick friendly and efficient, my service tech checked in at each step to give me choices and to make recomendations.
CM Heating did an excellent job from the first person who came put and talked us through our new HVAC systems options to the installers and most recently, Tobin, who came out and inspected a potential problem I reported and provided a ton of great information so we can optimize efficiency and longevity of our…
Dan Kelso came out to diagnose and repair our heat pump which had stopped working. He quickly found that the fan motor had failed and put in an order for the replacement. Despite a very busy schedule, he came out again in a couple of days to do the install after the part came in early. Dan was very personable and…
Emmanuel was great. Appreciate his quick work.
Carter came to our house and figured out what was wrong with our furnace. We are very happy with the job he did.
Friendly and efficient
