MM Comfort Systems did an excellent job at a very fair price for the install of our heat pump. They were extremely communicative with all our questions. The installers Rus and Dallas did a great job removing our oil furnace and installing the new duct work. I would definitely recommend to anyone doing HVAC work.

Sam and Tony installed a 2-stage Carrier furnace in our home. They did a professional job. I didn't fully appreciate my furnace until it stopped working. It was a classic case of you don't know what you got until it's gone. My spouse and I are thrilled with our new furnace and how it was installed. Thank you MM Comfort Systems.

MM Comfort Systems installed a Mitsubishi ductless heat pump at my house recently. The house was originally built with hydronic heating, so the mini split is an addition and provides AC plus a second option for heating. Had a very good experience with MM. The salesman, Russel, was very professional. The installers, Sam and Antonio, did a really nice job on the install and the installation looks extremely tidy. I can't comment on the long term durability of the Mitsubishi at this point since I've only had it for a few weeks, but so far its performing very well.
