A very positive experience. Everyone from scheduler, installers and the original quote were professional and a pleasure to work with.

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

We installed a new furnace and heat pump. The team was prompt, courteous, fast, informative and professional. They answered all our questions, were quick to explain any issues that popped up, and... kept our home clean through the process. They did a great job!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

MM Comfort Systems showed up when they said they would and did a good job. The heating and air conditioning works great. My only complaint, which is partly my fault, is I had left a free standing... shelf in the garage and told the installers if they needed anything else moved to let me know. When they installed the A/C drain line they let the presence of the shelf influence the location of the drain line, which they had to come back and re-position.read more

MM Comfort Systems installed a new heat pump for me. Their pricing was competitive. I was made aware of how the install would proceed, with both best case and possible challenges that can be... encountered. Mikel & Ina did a great job. Clean and professional workmanship.read more

I've hired MM Comfort Systems a few times over the years and I always got competitive prices and good results. They're my go to company for scheduled furnace maintenance and I've needed their help... for repairs with my previous furnace (which was about 25 years old at retirement). I request some quotes and do some comparison shopping each time and so far, they keep coming up at the top of the list.read more

What a great experience! From the initial phone call to completion, I am 100% satisfied. Joe and Russ who installed the heat pump did a top-notch job and made the whole experience a pleasure. And a... special thank you to Tristan, for helping in the decision-making process, he was the main reason I chose MM Comfort Systems out of three bids. I would definitely recommend this company, and if I ever need any heating/cooling needs again, I know where to go. Thank you!read more

First of all Mike and Alex did a great job of explaining to us what would be done and about how long it would take. There was a language barrier with my tenant so I asked if they could visually show... my tenant how to use the thermostat. They assured me that they would and offered to send over a coworker who spoke the language if they felt he did not understand. I felt they both were exceptional young men. They worked hard ,did a great job and all was neat and tidy when they left. I would like to mention our salesman Brandon Roberson and the office staff they were all top notch. I would highly recommend this company. I will definitely use them again.read more

We decided to replace our oil furnace with a heat pump and went with MM CS. The salesman Jason helped figure out exactly what we needed, which unfortunately included an electric service/panel... upgrade. But luckily MM was able to do it all with prices that matched other quotes.Travin and Kyo were great mechanical installers and I appreciate all of the work. Even when they ran into a hiccup they put in extra time and effort to make sure it was solved instead of pushing it to a later day. The work both them and the electricians did was very good and I'd use them for future install/maintenance work.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.
