Whatever your home, lifestyle, and budget we can create a solution to help you enjoy the perfect balance between energy savings and staying comfortable. Our brands have been chosen because of the high degree of confidence we have in them as industry leaders. Their products are tried and true and give our customers the assurance they’ll receive high quality, innovative products with the latest in technological advances.

Our High-Quality Units

A gas or electric furnace is the main component of a traditional heating system and may be combined with an air conditioner for a complete heating and cooling system. This combination is referred to as a split system.
A hybrid heating and cooling system is a variation to the traditional split system. It includes an outdoor heat pump that allows the option of electricity-fueled heating and cooling in addition to a gas furnace. It’s an energy-efficient and cost-effective way to heat and cool your home.
Ductless systems can be installed in places where conventional ducted systems cannot go or are an ideal complement to your home’s current ducted system. They can function as an air conditioner for cooling only or as a heat pump for both cooling and heating.

Your home is unique and your desires may be unique too. Some jobs are more challenging than others and require thinking outside the box. We’ll listen to clearly define your expectations and give you options so you can choose the right system for you. You’ll never feel pressure.

We will apply for and procure all necessary permits and post required stickers, as well as provide you with details for scheduling the inspection at a time convenient for you.

We'll Call You to Check In

We make it a priority to ensure your complete satisfaction. At the end of your installation, we’ll call you later that day just to make sure everything went as expected.
Testimonials From Customers
Our account manager, Kae, is very attentive and always makes sure any issues we have with our commercial HVAC are resolved. There has been more than one occasion where our heating went out when it was very cold and they made sure to send someone ASAP. Excellent customer service.

Our furnace went out irreparably during the pandemic in October, right in the middle of the heating industry's busy season. MM Comfort Systems, who we found through Costco recommendation, were the fastest company to come give a quote, gave a good price for fantastic equipment, and was able to install it weeks more quickly than the other companies we contacted. Everyone from the people on the phone to the sales people and the technicians we saw in person was prompt, generous with their expertise, and very professional. A+ would hire again!

We had a new furnace installed and were very pleased with the start to finish customer service! Rod the sales rep was very friendly, knowledgeable and assisted with our buying decisions and answered all our questions. Drew was our installer and was extremely helpful, informative, and patient during the whole day process. Kelly and Devon were the electricians that came to the rescue and were extremely helpful as well! Hannah followed up with our service and was very nice and helpful! I am very pleased with the outstanding customer service from everyone and would highly recommend MM Comfort Systems for any of your needs.

I had a new Lennox Furnace installed through a Costco promotion, so didn't really have a choice in hiring the installers. That's said, MM Comfort was a good choice! We struggled a little in the early stages of planning and contract signing due to lack of responsiveness from the sales rep at the time. Once you're done, no one will call you to confirm anything, not even installation date!The good choice was due to the technician who completed the job. He was very professional, knowledgeable, as well as extremely on time. He explained everything he was doing, and didn't leave until I had a good understanding of the new system.There seemed to be lack of communication between the sales rep and technicians, however, my tech was able to hold his end of the deal to which I am thankful.

MM Comfort Systems assigned Tom and Jordan for our installation. I'm a property manager and accustomed to working with a variety of service providers. Tom and Jordan were outstanding. My own house is a 1927 brick tudor style home and this presents some challenges for most any work. However, Tom and Jordan were highly experienced and the furnace and heat pump installation went smoothly. I would highly recommend MM and would also recommend that you ask for Tom and Jordan.

I’ve used MM Comfort Systems for regular maintenance since purchasing my house two years ago. Recently, my furnace wasn’t working just in time for the temps to start dropping. Tor has been the one to service the furnace and he does a top notch job. Always explains what the issue is and how he can resolve it. They are reasonably priced for the level of service they give. Highly recommend.

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.

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.

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.

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.

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.

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.

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.

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.

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. 🙂

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.

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.

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.

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.

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!

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.

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.

I would recommend MM Comfort Systems, Redmond. There were a few bugs to work through during the install, but MM has a deep bench of professional installers, and in the end, we are very pleased with how focused they were on our concerns, and the folks they sent out to problem solve some of those minor set up issues, were on site quickly, and stuck with it to our complete satisfaction.

We had a first class experience with M & M Comfort Systems for an air conditioner purchase and installation through Costco. Every step of the way the process was smooth and easy. Each employee was first rate:Jason Butler in sales, Shirley Wilkes in the office, Sam and Mark as installers. The price was right, employees considerate and capable, and the installation went smoothly. Thank you, M & M.

Thank you for providing World Class Customer Service! Tor called when he was 10 mins out. Tor removed his shoes before entering our home. He wore a face mask the entire service call and maintained social distancing. Tor is very knowledgeable and found our problem right away. He made several recommendations, which we will follow, to ensure our systems will be in top condition. The charges were very reasonable. Highly recommended!! Thank You Tor!!

Thank you MM Comfort for such a seamless experience.Brandon was our initial contact and he gave us our free quote. He was super responsive and respectful. With Covid we were very concerned about having people in our home. But Brandon (and Mike and Alex who came to install the unit) came with gloves, masks and he didn't wear his shoes in our house. We received our quote pretty quick and signed, paid within the week.We did have to wait about 3 weeks to get onto the books which sucked. But they scheduled us with really awesome installers Mike and Alex. They were super nice, knowledgeable and got the job done within a day. Super happy with the end product! Thank you!
