This company was amazing. They communicated very well with me and even after hours. I had a scheduling conflict, and my salesperson answered the phone after hours while he was home with his family (I was expecting to leave a voicemail, not bother him). They explained every step of the way so I had no questions. When it came to installation time, Mikey & Randall were awesome. They had great personalities, and were very respectful. My wife is a police officer that works night shift, and they decided to do more outside work early in the day to not disturb her. They also were very sweet to our 2 dogs and cat. They took the time to not only greet us, but greet the animals. They explained everything to us prior to doing it, and ensured that we had no questions prior to leaving. They cleaned up after themselves so well that you couldn't even tell they were there.The next positive experience we had, was with Hannah. She was the person I spoke to over the phone after the service. She was very thorough in explaining the process after installation. She is assisting me in setting up the inspections to make things easier on me. She even was kind enough to register the warranty for my product so I didn't have to worry about figuring it out.I firmly believe that many companies can install AC units without a problem. What separates these companies from MM Comfort, is the customer service and positive interactions that I had with these employees. I would highly recommend this company, and will continue to utilize them for my service needs in the future.

Joe and Ross were terrific. They arrived on time, installed everything efficiently and even cleaned up. Wish all companies could hire workers like these two!

I asked Randy and Matt a lot of questions the day they installed our new Lennox furnace and AC unit. They were very knowledgeable and provided me with excellent details. They did a great job with the installation and their customer was superb.

MM Comfort did a splendid job. Installers Adam & Juan were professional and you can tell they love the job they do. Seeing the dedication of their staff I will highly recommend MM Comfort to anybody in need of AC unit. The Lennox unit that I got is very quiet and it works really well.

The entire process was better than smooth from the time I met with a consultant all the way through complete installation. Every contact at MM Comfort Systems are courteous, prompt, and helpful (sales, service, office, installation) - contactless, quick, convenient, over email paperwork and they even help me register the product.Zach & Tyrce did such a clean installation: the ducts look nice, as if already part of the house (did not stick out too much) and keeping the work areas clean after they pack up. One of my existing ducts wasn't optimize for air flow and the team went above and beyond to fix it while they were installing in the attic.Glad I found MM through Costco.

Dan and Robert showed up on time and clearly spelled out the work they were going to do for the install. They did an excellent job adapting the duct work to fit an approved furnace filter I ordered in addition it integrating the A/C unit. The results were of excellent quality. They cleaned the work site completely, explained the function of the A/C and an overview of what was done and what features were added. I highly recommend MM Comfort Systems for their professionalism and quality of work.

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!
