Recent Reviews

4.50

(Based on 379 reviews)

Recent reviews often mention thorough troubleshooting, clear explanations, and respectful conduct in the home. Many note reasonable pricing and organized, clean installation work. A smaller number of reviews cite occasional misdiagnosis or communication gaps, particularly with thermostat-related issues. Overall ratings trend positive with consistent remarks about professionalism.

Shawn was our repairman. He repaired our boiler, took his time to evaluate the problem, and replaced the defective parts. M&M charged us far less than we were quoted by BluFlame, and did not try to sell us another boiler. He also did not tell us that our boiler was not worth fixing (we knew better!) The next time we need boiler work or decide to buy a new boiler, we'll be calling M&M! They did a fabulous job, for an affordable price (just over $1,000), and without the attitude and pressure of the other guys. THANK YOU M&M!

Jason Donaldson on M & M Heating and Cooling LLC

Great experience with M&M Heating And Cooling. Highly recommend for their expertise and care. Prices are definitely reasonable and affordable. You’ll get highly trained union members taking care of your home. Supporting talented local service men and women. Look no further than M&M Heating And Cooling to take care of all of your comfort needs.

After years of dealing with M&M, I have lost all confidence. The technician who attempted to service my furnace told me multiple times that my smart thermostat was the problem. He boasted he had thirty years in the industry but would only refer me to chat rooms if I pressed for a better explanation. As has since been confirmed by a separate HVAC professional, the smart thermostat was only indicating a problem with the furnace itself. M&M charged me each and every time they attempted to service this furnace, and charged me to replace the working thermostat. Still, when the furnace failed hours after their latest attempt, I contacted their emergency weekend services, but was never called back. My furnace is functioning now after minimal service from a separate HVAC professional, and I trust the advice they have given me about the longevity of the system.

Great business. Very trustworthy and professional. Very respectful of my home and patient with all my questions and concerns and willing to explain things in depth. I will not hesitate to hire them again and would highly recommend them to anyone. Kyle was fantastic and I felt completely comfortable letting into my home! Thanks so much.

Air conditioner install. Chad and his new help was very professional. Helper was only 1 month new but very good and they worked well together. Floors protected by their drop cloths (thank you). Very organized and excellent to have in home for 2 days. Cleaned up daily and left my home as they found it but with a wonderful new air conditioner. I will definitely recommend them.
