The team was extremely responsive to help us address our urgent need for a new furnace. Steve was able to get out to provide us a quote within a couple of hours of our initial call and the team was able to get the furnace installed next morning!! All in all it was less than 24 hrs from initial call to fully installed equipment. Mikey and Lucas on the install team were prompt, courteous, and quick! Appreciate the check-in and coordination from Hannah on the service team. Great customer service. Thank you.

Andrew and Chris were so nice and polite. They were right on time, walked me through the process, and reviewed how it would look. Then after installation they cleaned everything up and gave me instructions on how to use the system. The electricians arrived and did their part and everyone was out in 4 hours. Thanks!

installed a new AC unit. very clean and neat in their work. actually showed up at the time we were promised--that's a surprise in this business. one note--they did not tighten a gas line connection and when we smelled gas later that day, we called them and their service man showed up at 9:00 pm on a Friday night. he was here for 1.5 hours making sure the leak was fixed. he was polite and answered all our questions. thanks for being so diligent!

They gave the best quote we got. They installed during holidays and they were quick in their service. Installer's name was Sam and he was very professional.

Had a great experience with M&M through Tristan's partnership on identifying the right system for me along with a very easy and seamless installation leveraging Sam and Mark. I also appreciate Hannah stepping in to ensure my new A/C unit was registered so as to extend the warranty on my new system.

Installed a heat pump with MM Comfort Systems for central air in the summer and significant heat savings in the winter (we estimate over $1500 a winter in propane savings). They were in an out in a day unobtrusive, professional, gave me great options and far better equipment for the same price as other quotes I'd recieved. The system is working great, Travin and Kyo were great and even tolerated me doing some training with my dog around strangers! 100% recommended

I highly recommend MM Comfort Systems for their professionalism, great customer service, and quick response. Tom, who came out to give us a bid, answered all of our questions, and emails promptly. The installers, Drew and Lamont did a meticulous job with the install of our new furnace and AC unit. We had other bids, and this was the one we ultimately went with because of their knowledge, and quick responses.

We just had a new heater and air conditioner put in our home. MM Comfort Systems were fantastic! I got several bids, but there’s was the best by far. They were prompt with correspondence and the whole process was super fast. The estimator Rod Kippes was great and explained all of the options we had, teaching me about how the system worked and answering all of my questions. Install was beautiful and the installers Dan and Alex were so friendly and knowledgeable. They explained how to operate and maintain my furnace and taught me how to program my thermostat. I couldn’t be more happy with my new equipment and would recommend MM Comfort Systems to anyone needing heating and cooling in their home.

Zach and Randall came at a very challenging time for everyone (Everyone is currently self isolating at home) They were not only respectful of my home, but were very professional and were able to communicate and complete the job while maintaining a safe distance. They were on time and very efficient with their work. The system itself, while only a few hours old, really beats the window units I was using before. My only regret is not making the plunge sooner. Thanks MM!

I really like that they've incorporated virtual appointments and no contact service calls during a time like this. They've made maintaining our home's air systems super easy and are all very friendly.
