Drew and his partner were professional, courteous, and walked me through each significant change to install AC to my existing unit. They made sure I was satisfied with the work before the left and without question I was.

Installed a new furnace, very fast and efficient (heat wasn't out for long). Very low impact in the house and cleaned up fully when done. Great Job!

MM Comfort Systems provided excellent service installing an Electric Heater, HP and A/C, which replaced our oil furnace. Tristan came out to give us a bid on the work. He was thorough, knowledgeable and patient explaining what needed to be done, and answered all my questions. Many thanks to Joe and Ruslan for the excellent installation they completed expediently, which passed inspection with no problem. Justin did the work on our electric panel, even suggesting a clever short cut from the outside of our home to our indoor furnace room. He was in and out in no time at all. Joe and Ruslan were friendly, informative and very polite. They cleaned up everything, so that it was undetectable that any work had been done to our home. Communicating with their office was a breeze. Desiree and Hannah were available to answer questions and provide assistance when needed. Very friendly and helpful. Great company, great employees, great job and reasonable cost. Should the need arise, I would hire them again.Cathy Kennedy2/22/21

My heating system needed a repair. MM was able to send a technician the same morning I called them. The technician sent me an email to inform me that he was on his way to my house. When he arrived, the technician quickly made a diagnosis and ordered the part needed for the repair using a mobile device. MM called me the next day and told me the part can be installed the following day. The technician arrived in the morning during the scheduled hours and installed the new part without any problems.Overall, MM was very responsive, professional, efficient, and easy to work with. They fixed my heating system in 3 days. I got heat back before the big snow storms hit the Seattle area. I am very appreciative of the service they provided.

MM are AWESOME!!!.We recently decided to add an AC through Costco. From the representative I spoke with at Costco (Christy), to the end with Ryan and Tyler being our installers, everyone was courteous, professional and very friendly. The company responded quickly and the appointment was scheduled right away. The sales representative, Bob H. was very nice and explained the process in easy to understand terms, helping us to make the right decision. The office staff (Desiree, Jenah and Hannah) were excellent in their communication and on-point with permitting, warranties and other documents.Everyone that came to our house was very respectful of the property. Ryan and Tyler worked around the existing features and after the install left everything spotless. They were great on the final walk-around and explained the equipment and features.A great example of businesses adapting to COVID- everyone always wore masks, distanced, and were very safe. Very pleased and would not hesitate to do business with, or recommend MM Comfort Systems.

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!
