Furnace Installation, Maintenance & Repairs Renton, WA

Electric furnaces are a popular and very conventional choice for homes. Their principle of operation is quite simple. They first use electricity to heat internal components. Then the air is sucked into the unit. As it passes through the heated electrical components it warms. That warmed air is then distributed throughout a home, thus providing heating. They’re safe, reliable and MM Comfort Systems can install them in a timely manner.

Gas furnaces hold a lot of advantages over alternative systems. Depending on your Renton home’s needs, they may just be right for you.
Providing massive heat output and fast temperature control, a gas furnace is perfect if you’re looking for power without sacrificing efficiency or reliability. Gas units burn natural gas rather than rely on electricity for heating. And for residents with access to a gas line, can sometimes provide cost-saving benefits. One downside is that gas furnaces can be dangerous. They can spew toxic gases and catch fire if they aren’t properly installed or serviced. That’s where MM Comfort Systems comes in. With our decades of experience, you can relax and rest easy knowing that everything will be managed professionally.

After the last heat wave in Seattle with temps crossing 120F, we decided to install an AC and signed up with MMC Comfort Systems through Costco. Tom and Jordan from MMC installed Lennox AC, new Lennox furnace, new Lennox thermostat and filter, and installed new duct system on the second floor so the air can be circulated through the whole house and the whole house gets cooled not just the first floor. We are very happy with the work Tom and Jordan did, excellent quality! We had concerns with routing new duct system as it required cuts thru the ceilings and hardwood floors. Indeed it was quite challenging but Tom and Jordan did a great job minimizing cuts through the hardwood floors and the ceilings. Great quality work, they just nailed it on the first try, super pleased! Tom and Jordan are top notch professionals, glad we had them install our new AC and thank you MMC!

MM Comfort Systems installed a ductless mini split AC/heating system on my house and I couldn't be happier with the quality of the install. Bob was extremely helpful early on in the process helping us decide what made the most sense for our home, helping us make high quality decisions throughout. Adam and Marc did an incredible job installing the entire system and we couldn't have been happier with their attention to detail. Highly recommend working with this company!

Drew & Jason did the professional install.These two worked hard getting the furnace up in the attic. They had to cut the access opening a little wider and they did a clean neat job and not tore up the access hole. I was afraid I would need to replace the whole ceiling but it was very minimal, just a touch up needed later. I had many questions about the system and they were very detailed with explaining it and how to operate the new system.I even asked Jason to take a look at my gas fireplace for an opinion. Also, Drew explained to me what a heat pump was and what is was needed and used for.To summarize a long story, the two (Drew & Jason) did an excellent job with their craft. I went through the COSTCO program and MM Comfort Systems made it happen. I am liking my iComfort E30, I can monitor the house comfort anywhere in the world, while I'm outSnowboarding or Surfing! 🏂❄️🏔🏄‍♂️🌊🏔Mahalo and Thank You!Also want to Thanks Hannah for doing the registration for me which gave me another 5 years of warranty time for the heating system.She also set up the post install inspection with City of Renton for me which only took about 10 minutes or less.Also, Tom Dempsey, who did the initial consultation, and explained thoroughly in detail to me the 3 different Lennox models that would suit my heating needs.

The estimator was excellent...thorough, informative and communicative. When I chose to go with MM Comfort System over the other three bids I received, I continued to have outstanding communication with the staff about scheduling, payments and answering my many questions. When the installation crew arrived, what was impressive was they got right to work....no coffee/chit-chat time....they were very hard-working, very responsible, and kept me updated about what they were doing and their progress. After the job was completed, the office staff was so helpful, sending me information about inspections, completing the product registration for me and just being professional. Great job everyone!

The installation team made up for any shortcomings I had with the sales team. Tyler and Ryan did an awesome job on the installation. They showed up on time and were very professional. The finished product is the result of two guys who take pride in their work. MM did all of the hvac during the construction of my home this year so I was more than happy to have them come out for the installation of ac after some unexpected heat waves. Recommend the installation team and this company 💯

The HVAC team and electricians were very professional. They took me on a very thorough walk-through of what to expect, and answered all of my questions. They finished the install and then walked me through the inspection and warranty process, and the operation of my new unit. The crew was friendly to my dog, as well! Great experience.

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!
