I bought a furnace to replace an old inefficient system and they went the extra mile helping me decide what system would work best for me. My install was a little complicated and they went above and... beyond to make sure it was done right. Now, a little over a year later they are still going above and beyond giving great service every time I call. I would recommend them to anyone looking for a good, honest HVAC shop.read more

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.read more

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.read more

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.read more

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.read more

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.read more

We had our furnace replaced (to one properly sized) as well as AC added. Timeline was great and the installers Matt & Randy did a great job with making our furnace and ac look great.

I installed the heat pump system with MM. They have the best price and their service is great. Mikel and Ina installed the system for us. They are very nice people and they change shoes when they... get into the house, and they wear masks throughout the whole process. Hannah at the office is super helpful in getting the permits and helping me understand the whole process. It is a pleasant experience.read more

Allen was awesome! He showed up early, he was friendly, efficient, and super thorough. The job wasn’t exactly as he expected, but he adapted with a smile. I wasn’t home when he completed the job, so... he sent a text with pictures and a detailed explanation of everything he did, with some additional user instructions. Really appreciated that! I would absolutely recommend MMCS to neighbors and friends.read more

MM Comfort handled replacement of an existing furnace with a Lennox furnace. This was done through the Costco program. The whole process was very professional. The install was particularly good.... Carpet was cut around the previous furnace and the installers, Mike and Randall, did a great job of building in the new furnace to match with the flooring. My house was cleaner after they left. There was no rush. They answered questions, explained everything. All docs were handled. I am a critical reviewer and I can't think of improvements. They even had the city inspector out the next morning. It was a great experience. Thanks MM. I would happily recommend you.read more

Vitalii came out this morning and did an excellent job maintaining my AC system. He cleaned the filthy condenser coils (extra service which he priced and I approved beforehand), checked out the AC... system's operations (wearing shoe covers when he came inside to check the temperature of the vent airflow), and he cleared a blockage in the condensation drainage pipe. It wasn't cheap, but I don't know what others charge for the same services, so I can't judge the value. All I know is Vitalii arrived on time, did the job professionally and quickly, and couldn't have been nicer, and that's an "A" in my book. 🙂read more

Sam & Mark replaced my furnace in 4 hours. Their ability to handle this quickly and without asking many questions allowed me to continue being productive while working from home. As a bonus they... kindly let me know about a leak happening nearby and outside their work area which allowed me to minimize water damage.read more

We had a Lennox furnace installed by MM Comfort Systems on Monday. We bought the service through Costco. The installation was scheduled really fast and they actually gave us an even earlier date... since they got a cancellation.Sam and Mark showed up in the morning at 7:30 am sharp. They worked hard and installed also the thermostat. After installing the furnace Sam showed us how the thermostat worked and before leaving they cleaned up after themselves. The only thing that we wondered a bit about was the filter unit that was already there - they replaced the filter, but with a too small one! We ended up replacing it with one of our own. Otherwise, the service was great and fast and we were pleased with the result.read more

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.
