What our Customers are Saying!
Zach & Jeremy came in to replace a furnace and install a new heat pump. We went with the Carrier Infinity system and they did a really professional job with the installation. They were prompt, on time and courteous. They did a good job and everything passed inspection without any issues. Plan on using MM Comfort Systems for all our HVAC repairs and maintenance.

Really pleased with my experience. Installation was timely, the staff were knowledgeable and our AC works great. Pricing was transparent and reasonable for what we get. Not sure what else you can ask for.

The mini split system we purchased works great! I have lived in this house for over 40 years and expected the system to be good, but this is fantasic! We purchased through Costco and got a great price. The installers Mikel and Ina were efficient and friendly. They left the areas where they worked completely cleaned up! I highly recommend MM Comfort Systems!!

We had A/C installed on one of the hottest days so far of the summer. The installation team worked so hard in the heat and did an amazing job. Great experience all around. Thank you!

We ordered our mini-split duct a/c system from Costco, who used MM Comfort Systems as the provider. MM did a great job, especially our two installers, Matt and Alex, along with Jennah and Hannah in the office. thanks.

This is the second time I've hired MM Comfort Systems, first time was through costco, 2nd time I reached out directly. They replaced an old furnace and installed a new AC. They were professional and on time. When they got here they looked through various parts of the ceiling and wall to determine a least intrusive way to route the AC coolant lines. Their patchwork was also well done aesthetically. They installed the components and AC was up and running within 8 hours. Drew and Jason did a great job with the unit, I have already recommended MM Comfort Systems to some neighbors.

I'd like to split my review into two parts, the actual installation, and the process leading up to it. The day of installation and our techs Randy & Clinton were amazing, very professional, quick, and responsive. Our units work perfectly and the installation was painless.However, the lead up to installation was a real pain. I had to go back and forth several times with the initial planner because they kept sending docs that had the AC Units in the wrong place and were missing key elements needed for our HOA approval. In general, our representative was non responsive and I had to call customer service several times just to get them to respond to an e-mail. I understand that this is an insanely busy time in Washington for HVAC installation, but this part of the process was a pain through and through.Overall, the end result is great, so I can't complain too much, but be prepared to have to do some legwork in the lead-up.

Jonny was a great electrician. He went an extra mile to teach us about the generators and other safety and practical tricks. Really satisfied with his work. The company provided a better bid than several others bids. Very satisfied

Sam & Zach installed my new Heater and AC system on time for this year's hot weather. They were very professional and he seems to be very detailed oriented in making sure the installation not only done properly but looked good , even facing the PVC pipe printing to towards the back. I used this company when I purchased my new heating and cooling system VIA Costco. I will highly recommend their services for others. Although the installation took a while to schedule due to their busy schedule and lack of supplies I was told. I choose the high efficiency furnace this time to save on gas and energy. Now waiting for my $2,300 refund.

We're delighted with the expert HVAC installation by Mike & Jeremy of MM Comfort Systems. Especially pleased with their suggestions to change locations of outdoor compressor and one indoor unit that work much better than what salesman had advised.

We had MM Comfort Systems install a whole house water filter and a new water heater along with installing a new kitchen faucet and a new pressure regulating valve. Chris and his apprentice did a great job. They work was clean and has performed well. We had an issue with the hot water circulation pump but Chris made the corrections. Only reason for the 4 stars is that it took quite a while to get the proposal for the work.

Recently had heat pump with mini-split units installed. Luis and Mario arrived on time each day, were considerate and professional. When a change was required, Luis explained why and what the change would entail. The work was completed in a timely way and they made sure all the units were working before they left. They picked up after themselves and left the site clean.

Mikel and Ina installed our new gas furnace and thermostat. They arrived on time and worked through the morning. They kept us informed and showed us how the unit was different, how to change filters and use the new thermostat. The old unit and all materials were removed, everything was left in great condition.
