Highlights
- Thorough check — verified everything ran properly before leaving the job
- Personal service — owner John explains the work and preps systems for winter
A February 2026 review says CM Heating and Cooling installed an air conditioning system and repaired another unit, calling the technician professional, punctual and thorough about checking everything ran properly before leaving. CM HVAC LLC, trading as CM Heating & Cooling, is a Danvers company repairing, maintaining and installing residential and commercial heating and cooling equipment — mini-splits, heat pumps, boilers, central air and rooftop units. It says it has been in business 30 years. Two reviews from late 2025 describe similar work: a new heating and cooling system installed with thorough cleaning and questions answered, and owner John personally servicing an aging heater ahead of winter, described as taking the time to explain what was going on rather than rushing through it. The written record is short — three reviews, all within the past year — but consistent on the same points: professional, communicates clearly, and checks the work before calling it done.

I had my air conditioning system installed and another unit repaired. I couldn't be more pleased with the service. From start to finish. He was professional , punctual, and extremely knowledgeable. He answered all my questions, and made sure everything was running perfectly before he left. I highly recommend.

A new heating and cooling system has been installed. Every stage of work, including cleaning, was done thoroughly and professionally. I received answers to all my questions concerning the system.

I can’t say enough good things about CM Heating. John, the owner, came out and took care of my old heater. He was professional, knowledgeable, and made sure everything was running perfectly so I’ll be ready for the winter. It’s rare to find someone who takes the time to explain what’s going on and does the job right. Highly recommend John and CM Heating if you want honest, reliable service!
