See What Our Customers Are Saying

We work tirelessly to build long-term trust with our customers which is reflected in the reviews below.

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 during the end. They communicated everything they were doing and any changes that needed to be made. The office communication from Brittny has been outstanding. We had our furnace venting and water heater venting replaced by Hagen and Aaron back in January 2026. They were also fantastic, quick, efficient, made sure to drop cloth our floors and wear booties in our home. The amount of effort and care this company puts into making sure the customer is happy is incredible. Something very tough to come by these days. CM has been honest, upfront and reliable. Your staff is remarkable and goes above and beyond. Keep these people around! -Two incredibly happy customers 😊

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 drain line causing water to backfill into the pump, causing noise after it stopped running. I felt that Michael and Dan went the extra mile to help remedy the noise issue and did a fantastic job rerouting the PVC line. We ended up with a clean look, eliminating the PVC line in front of the coil panel, allowing for easy access. No more condensation pump, no more noise, and a clean look. Job well done! PS: I forgot to mention that Anderson C. arrived on time; he performed the yearly maintenance and did a fantastic job as well! Great teamwork! To CM Heating Staff and Techs, Thank You All!

Emmanuel and his trusted sidekick performed outstanding feats of excellence that have seen no match from mere normal technicians. They took a sows ear and turned it into a silk purse. The careful removal and re-installation of our existing split system has been a experience that should be witnessed by all. The total job was beyond reproach. It was a pleasure working with such professionals. There's no beating CM Heating

Amber Maddalena started the process walking through CM’s warranty on mini-split installation in our condo. They ended up being the lowest price and their 12 year parts and labor warranty was the best of any company we quoted (we got 4 quotes). Amber worked with me through the process (we were the first mini-split installation in our HOA community) meeting with the HOA and their engineer to ensure the system met all requirements. Amber was fantastic! The installation (an outdoor 30k heat pump, 2 each 6k indoor units in bedrooms and an 18k in the living room) was completed in a day. The installers were very professional and after completion both the HOA project manager and the engineer were very satisfied with the results. And we have a condo that is not sweltering anymore. I highly recommend CM.

Greg Rice

CM heating is the most professional,reliable, honest company we have ever dealt with. They are also very reasonable in their prices for repairs. They send a text with the technician’s photo so you know who is going to come to your house and what time they are on their way! The technician, Hagen, was so personable and knowledgeable. He quickly diagnosed our heat pump issue and explained everything to us so we understood exactly what was wrong with it. He and his apprentice quickly did the necessary repairs. We are so thankful we will have a/c heading into summer!
