MM comfort is definitely one of the top and most popular HVAC contractors in greater Seattle area. I waited a few weeks to get the system installed but worth it! Adam and Marc did a great job making sure the system is installed and working properly. They even helped to install the Nest thermostat that I purchased separately and shown me how to use it.
Jamie Yu19:52 04 Aug 21Great experience, great responsiveness! Jason answered all our many questions before install and worked with us to get exactly what we wanted/needed lined up. Tom and Jordan were friendly and professional installers and worked quickly and efficiently. We’ve been enjoying our new AC system greatly!
anne black22:05 30 Jul 21Dan, Zach and the entire team at MM comfort systems are amazing. We purchased and installed a heat pump for our split level home. Dan and Zach were able to plumb the system into the house and fish it through the ceiling to conceal much of the piping. Impressive. They were here all day working hard to get our system up and running the Friday before the heat dome/wave hit. The level of care, effort and explanation was fantastic. I highly recommend this company for all your HVAC needs.
Robert Williams04:08 29 Jul 21From the initial bid the to installation, using MM was easy. I’ve used several contractors as I’ve been updating our house over the last few years and they were one of the few that was fair, on time, and professional.
Brad Mott19:02 27 Jul 21Using MM Comfort Systems to select and install our AC unit was the best experience. From the consultation and estimate with Vince to the installation with Joe & Joseph, everything was seamless. Everyone was so nice, so helpful, responsive–all the things you want when working with a company. We will definitely be using them again when we get a generator or any other services!
Keri Ferguson-Smith03:20 23 Jul 21We were impressed with the overall service and timeliness of everyone in the organization!
Arlene Hanson03:14 20 Jul 21
Bryan Solemsaas20:29 19 Jul 21Drew and Rock did great job explaining the process in advance and providing updates. The work they did looks very neat and professional. Clean too. Everything works to our satisfactions. Thanks!
Dan Kissin20:21 14 Jul 21Beautiful install. We love the system. Both inside and outside units look great. Mechanical crew cleaned everything up and it looks great. Electrical crew installed wiring as requested through unfinished basement. Only issue was electrical cleanup. Spent about an hour vacuuming up shavings from the holes they had to put through joists.
Lee Winstrom19:29 12 Jul 21From start to finish the process was very seamless. The consultant, Steve Vick, was great to work with and very knowledgeable. The installers (Sam, Joseph, and Antonio) were courteous and very mindful of our home and took proper care to ensure our home was in better condition than when they got there. Upon completion they gave a thorough walk through of the system and took the time to answer all of my questions in extra detail. Will definitely recommend MM Comfort Systems to anyone looking for Furnace/AC help!
Sterling Nelson17:27 09 Jul 21Installer came at 8am and finished work almost at 6pm. Great work on installation and clean-up but the only problem I had was “measure 2x and cut once” was not followed in looking for wire connection so several holes were cut on my garage ceiling that I have to repair. Office helps you file for rebates and make appts for inspection.
Teresa Brown23:17 07 Jul 21On the hottest day ever Sam & Russ put in extra effort to get our new A/C installed. It was grueling but they worked tirelessly to get the system installed and did so in a professional manner. The unit looks great and has functioned perfectly. The time they spent dialing it in after the install demonstrated their professional rigor.I collected 10 bids before going with MM Comfort Systems. They weren’t the lowest bid but the confidence they conveyed during the bid process carried through to the install. I would definitely recommend them!
L D K03:26 07 Jul 21MM Comfort installed our central AC for us. The entire process was enjoyable and painless, starting from Bob who did the initial consulting, to Mikel & Ina who did the installation. Bob was able to identify an unused breaker in our electric panel and helped us avoid a panel replacement. For the installation, Mikel & Ina were very professional where they made sure to keep us well informed in the process and were able to finish in a very timely manner. In addition, their knowledge and expertise really helped to avoid necessary steps. Overall a very satisfying experience, and would recommend indeed.
David Liu07:28 05 Jul 21Sam, Matt, and Antonio installed our AC. They were friendly and kept us informed. They ran into some unexpected issues but they put in the extra effort and time to get it installed.
Gregg Hirata03:16 04 Jul 21From start to finish, MM Comfort Systems did a fantastic job. Jason the Sales consultant answered every question and accurately described the process. Joe and Joseph the install technicians were respectiful, courteous and left our home clean.The whole experience was pleasant and truly a value. I cannot believe I waited this long to have A/C installed.
Jeff Daub18:02 02 Jul 21We had one minor issue with what the salesman said could happen vs what the installers were able to do. This did delay our installation by 1 month. It is now installed and is running and cooling excellent. We have a tri-level and were concerned with even cooling, but its cooling all levels great. The installers were very professional, they called prior to arrival, were knowledgeable, and cleaned up all areas they worked. The final installation is very professional in appearance and works as promised. I would recommend to my friends and family. The only reason I gave four stars was the delay of installation due to the issue with what the salesman said and what the installers could do. We love the cool air!
Carol Allread20:44 01 Jul 21We decided to purchase AC for our home this year via Costco. Vince came out to provide us with a quote and walk us through all of the available options we had in terms of where we could locate the unit, what types of units were available, and other recommended products and services. He gave us clear answers to our questions and didn’t try to upsell us to something we didn’t need – we were thoroughly informed and able to make choices that were best for us.Sam & Antonio did the install. They were quick and professional and answered all of the questions I had about how to operate the unit, what the status of the work was, etc.I deducted one star because there was a part that was defective (not their fault) and Sam informed us that the office would reach out to us after they left to schedule someone to come by and replace it. I ended up having to call them after a business day and a half (plus two weekend days) of awaiting further information. I assume they were probably VERY busy but knowing that the inspections were pending had me really anxious.. With that said, this was incredibly minor – just a small point of improvement.When I connected with Hannah in the office by phone, she was incredibly professional, quickly got a technician out to finish the job, and even took the time to register our unit for us.Everything has been working flawlessly the last month and kept our house nice and cool, even during the record breaking heat!I would highly recommend MM Comfort Systems! Thank you, team, for your hard work in helping us join the COOL KIDS on the block this year 🙂
Melissa D02:39 01 Jul 21The MM crew showed up on time and got right to work. They kept me informed and explored the best possible solution for my AC installation. They were all friendly, courteous, and professional. I love my new AC!!
Chris Cooper22:17 30 Jun 21MM comfort system did my A/C unit installation in a professional manner .Technicians Travin and Antonio did awesome job.
Jobi Paul19:34 26 Jun 21Our install was back in February but wanted to make sure to leave a review for Joe and Ruslan at MM Comfort Systems. We liked how fast they completed the install. They stayed in constant communication and even alerted us to the water heater leak which was completely separate from their job. Even found a bucket in our garage and placed it at the leak site. This saved us a lot of money and headache in the long run. Cannot express our gratitude enough.
Erica S21:08 25 Jun 21Tom and Jordan did a fantastic job with the install, and made sure to clarify with me before any subjective decisions are made. Very happy with the work.
Jacky Yip04:50 25 Jun 21Process went great Sam and Antonio answered all our questions and did a great job.
Richard Brigman20:50 24 Jun 21The whole crew was awesome. They where very professional and clearly explained everything that was going to happen showed me everything after they finished and cleaned up after themselves.
Todd Knopp13:06 21 Jun 21Great service! Dan & Zach are awesome, they also helped move the plants!
Lasifu Ta19:36 18 Jun 21Very easy installation of a new gas furnace and new to the house AC. Tyler & Ryan were very polite and COVID aware, they took care of everything and walked me through how to operate everything. The new system passed the city’s inspection on the first visit.
Eileen Burns Caparoso18:43 13 Jun 21The install technicians, Sales team and customer service did an exceptional Job. They were very courteous, knowledgeable. They did not disrupt our house during their installation at all. They clearly explained everything about the use of our new AC installation. I highly recommend MM comfort system.
Michael Maddox15:39 12 Jun 21I would recommend MM Comfort Systems to those looking to install AC or a new furnace. The installers, Sam & Ruslan were efficient, clean and knowledgeable, in and out in two days, one day for furnace replacement and one day for new AC. From start to finish MM employees were polite and efficient, knew the correct installation for new electrical, heating and AC. All passed inspection.
George Jonson12:38 10 Jun 21We found the worst situation possible when having a different company come out to quote repairs on a system we inherited with the purchase of our home. The furnace and AC were broken and red tagged, that other company quoted a lower quality system replacement at 5K more than MM. Jason was a great no pressure salesman who gave good recommendations on system selection based on needs and budget. We agreed on the price and got it scheduled ASAP. Sam and Antonio arrived to our house right at 8am when the noise ordinance shuts down for the morning and proceeded to uninstall the ratnest of an old system and cleaned up the install and put in the new Carrier system which has brought us much comfort and sleep for the last week. THANK YOU THANK YOU THANK YOU as my 3 year old would say.
Colby Crouch21:08 09 Jun 21Sam & Antonio were professional and friendly. They left no mess. They cleaned up. They were actually very good with the install and took off shoes when entering the house. Highly recommend!
Mai Mai05:02 04 Jun 21Our installers Travin & Kaelen were very friendly and polite and considerate of the home environment. They did a clean work and we really appreciate their efforts. They answered to all the questions and gave wonderful suggestions that were very useful for the whole installation procedure. They did a great job! Overall the experience was good and would definitely recommend Travin & Kaelen working for MM comfort systerm.
Sai Priya Kumar21:25 03 Jun 21Tom and Jordan showed up early and were super professional. Even when the original plans didn’t work out as we thought they might, they were happy to just adapt and do what needed to be done instead. All in all I’m super happy with their work and glad I went with MM Comfort Systems. I’ll definitely be using them again for any work that they service.
Keith Horton06:06 30 May 21Randy and Matt were efficient in replacing my old heat pump with a new system. There was a small issue that had to be worked, but MM Comfort Systems diligently worked the issue until resolved (thanks Shaun!).
Kevin Sandal18:18 27 May 21MM Comfort Systems installed a heat pump HVAC/air scrubber along with replacing an aging electrical panel and we couldn’t be more pleased with the end result. They did not sub-contract out any of the work and made sure we were 100% satisfied with the final product. Tom & Jordan were very professional and they didn’t mind me being curious and nerdy about “how things work”.When drilling for the thermostat wire, the in-ceiling power line to the water heater was accidentally damaged (just bad luck) and when we realized the next day that we had no hot water, they sent out a team ASAP who quickly identified the cause and made it right.I would not hesitate to recommend MM Comfort Systems!
John Bartlett17:11 21 May 21Thank you the MM Comfort Systems team for providing great customer service from beginning to end. Todd our sales rep was friendly, knowledgeable, responsive and walked us through each step. The team the installed our electrical panel was quick, knowledgeable and professional. Our installers Tom and Jordan were on time, super clean, friendly, professional and kept us up to date on their progress throughout the day. The end result was amazing clean air in our home. We are very grateful. There was one hiccup with the install that showed how committed they are to doing the job right. There service department was quick to schedule a team to come back out within hours. We are so excited to start this long term relationship with MM Comfort. Finally, thank you to Sherry in the accounting department. She too was great at communicating. It takes a team to provide great customer service. Thank you all for changing our lives with your amazing product.
Jessica Bartlett04:08 21 May 21Matt & Randy executed a professional install for a new furnace and whole-house AC system. Their attention to detail was evident from the precise installation of the furnace in a tight space (1/4″ clearance) to the caulking around the gaps between piping and walls. MM Systems coordinated the whole job, including permitting and product registration. Highly recommended.
Mihai Aldea22:44 20 May 21I had an HVAC mini split installed and Joe,Joe, Mike and Mike’s associate (sorry I didn’t get his name) were on time and worked efficiently and got the unit installed within 5 hours. They cleaned it after themselves and were very helpful and friendly. A great experience
Linda Paramore19:19 20 May 21We are a long time customer of MM Comfort Systems.We have had a heat pump system for over 40 years; but it needed replacement. Installation was by Adam and Marc who were efficient and thorough. There were no short cuts and clean up was superb. The electrical inspector just completed his inspection and said the installation was totally up to code.
John Gentry18:14 20 May 21The whole project is very smooth. Very effective communications keep me updated from the sales stage (Steven Vick) all the way through the finish line of the project. The installers Sam & Antonio are very customer-oriented and friendly. they kept me updated with the progress of the installation. Also important is that I can see there is a strong team to support the whole project, and that’s why I chose MM Comfort.
Alexander Wang05:37 20 May 21I used MM comfort Systems to install AC in my house. They reused the existing ductwork, added the heat pump, and replaced the furnace. The whole process from initial contact to install was only 2.5 weeks. Adam and Mark were very knowledgeable and professional. They got brought up anything that wasn’t expected and offered options for solutions. Great crew, would hire again.
Alex Lamb22:42 19 May 21Mikel and Ina installed a mini split for me. They arrived on time and were very professional. They both did a great job inside and out.
Erlinda Jimenez04:39 15 May 21I was very satisfied with the new furnace, it controls the heat and sound very well. It was well done.
Irene Lee18:39 12 May 21This is the second time I’ve used this company to install furnace/central cooling and they were great both times. The employees were friendly and enjoyable to chat with and very informative when I had questions or concerns. Rod the sales guy is awesome!
Holly Fuerte15:52 03 May 21Mike and Jason Installed our Lenox Furnace. They were courteous, skilled and informative. The whole experience was very positive. Mike and Jason did a great installation and totally gave us all the info we needed.
David Kirdahy02:51 01 May 21From the initial meeting with Jason to get a bid on my project to the furnace and AC installation by Chris and Kaelen, working with MM Comfort Systems was a fantastic experience.Jason and the MM office staff answered the million questions I sent their way quickly, patiently, and accurately.Chris and Kaelen then worked extremely hard to install all the components, and the place was cleaner when they left than when they got there. They arranged all the permits and inspections, so the project could not have been easier from my end. I am thrilled with the Carrier hardware that was installed.
Phil Hutchinson17:53 28 Apr 21Tom & Jordan were very professional, friendly and their work looks great. The rest of the team at MM Comfort Systems were very helpful as well.
Graham Watts22:18 21 Apr 21Responsive. Great quality product. Installers Drew and Lamont were on time, efficient, wore masks and left the area clean and tidy.
Carina Moravec02:14 21 Apr 21Sam and Juan, with MM Comfort, were on time and professional. They got it done in reasonable time, packed up, and we were good to go. A new thermostat was necessary and was installed, at no added cost. The warranty is great, and we have the added advantages of the Costco guarantees.
Philip Shack22:10 15 Apr 21
Jessica Wyckoff19:20 15 Apr 21My quote was with Tristan. He answered all my questions and guided me to the best option for my family. Matt & Randy did my install. They were great. My Lennox condenser in the bottom of my furnace broke during the pressure test and let refrigerant throughout my house which was unfortunate, but nothing installers could have changed. They had to come back 2 days later, replaced the condenser, cleared the line and installed new refrigerant. All is working great after that. I’m happy with my choice with MM Comfort Systems.
Mr White06:32 14 Apr 21The price was great. We went through Costco and MM is who contacted us for the quote. The quote was fast and affordable and the installers Drew and Lamont were friendly and communicated with me throughout the process.
Jennifer Canter19:27 13 Apr 21Travin & Kaelen were professional, friendly and speedy! Our AC was installed in one day, and upon completion, everything was explained to us in plain English. The whole procedure was minimally invasive and overall really well done. Thanks!
Sidney Field18:09 13 Apr 21They followed up until they were able to get the heat pump system fully operational. Very pleased.
Michael Mulvihill18:21 10 Apr 21
Caden Nguyen22:34 09 Apr 21
To To21:58 09 Apr 21I used MM Comfort systems to replace our Furnace and we couldn’t have been happier with the technicians that installed it. They were professional and made sure install went as smooth as possible. The sales team missed something so the techs had to be creative to solve it all while making sure I had an A+ experience. They also arranged inspection which saved me time from navigating that. Thanks and would buy from them again.
Johnny Blair19:43 09 Apr 21I love our new furnace, it’s so quiet and I noticed within 2 days how the air filter system made the air feel so much cleaner. With two big dogs in the house it really made a difference and keeps the dust down. I can’t wait to try the A/C this summer. The installers were great, helpful and friendly.Thank you everyone.Luanne Schreibe & Wayne Matta
Wayne Matta18:52 09 Apr 21Professional and friendly service. Travin and Kaelen were outstanding 🙂
Sunny Heinrichs17:05 09 Apr 21We cannot say enough good things about MM Comfort Systems! We had a unique situation, and needed to have our furnace removed in order to access and repair a leak in our foundation. We had reached out to MM Comfort Systems to coordinate our furnace removal a few months in advance for that project. This made me nervous because the timing was not flexible, but MM was extremely communicative and arrived right on time the day that they were scheduled to come out.We were also curious about adding an AC unit to the house at the same time of having our furnace work done, and asked to schedule a consult. Bob came out to give us a quote and he was thorough, friendly, and did not pressure us at all. Well, he quoted us such a fantastic price, we decided to have an AC unit installed as well. When the day came to remove our furnace and install our AC, Joe and Dan could have not been friendlier, more courteous, or more professional. We were even offered a space heater because we would have to spend the weekend in our house without heat! Everything about our new AC unit was explained, and our furnace was efficiently removed and reinstalled good as new. On the office end, Hannah and Jenah were very friendly and knowledgable and made the permit process go very smoothly as well. We would not hesitate to recommend this company to our family and friends. Thank you for a wonderful experience MM Comfort Systems!
Audrey McGill20:50 08 Apr 21We had MM Comfort Systems replace our 20+ year old gas furnace with a Carrier Performance 96% AFUE gas furnace.After getting quotes from 4 other HVAC vendors, we opted to go with MM Comfort Systems — their prices were reasonable, they had good reviews and their work included a 5-year “peace of mind” guarantee.Tristan, who came to do the estimate, was friendly, knowledgeable, patient and the very professional, and Zack who was part of the 2-person installation team, was the same (our furnace was installed in 5-6 hours, and we appreciated the fact that the guys cleaned up afterwards). I accidentally turned off the furnace after the installers left and 1-2 hours later, we had no heat and the thermostat was dark. I called MM and within 30 mins, Zack called back to help troubleshoot remotely (and was good natured about my faux pas). That’s the Good.The Bad:1. The other installer, who was also friendly, didn’t wear his mask all the time, and when he did, often had his mask below his nose.2. On Saturday, 4 days post-installation, I opened the closet to check on the furnace and found water on the floor. I called MM’s main line, left a voice mail; also called the CEO’s direct # but his mailbox was full. Couldn’t find a 24/7 phone # to call even though their web site refers to one. On Sunday, after replacing 4 towels that we’d placed on the closet floor to absorb the leaks, I emailed MM to ask them to send someone out ASAP.UPDATEMM Comfort Systems called first thing Monday morning and had someone over to fix the leak within hours, so I’ve changed my rating accordingly.
Fiona Lee15:26 06 Apr 21
Bitewa Wasse03:35 01 Apr 21The team from MM Comfort Systems came out to install a Lennox AC unit and they did an excellent job. They arrived on time and Matt walked me through what needed to be done, patiently and thoroughly answering a couple questions I had. Work was done efficiently and expertly. They discovered our furnace had at some point developed a cracked heat exchanger and needed to be replaced, which was unfortunate but unavoidable. I really appreciated Matt showing me exactly where the furnace was cracked and explaining the issue. MM had a new Lennox furnace in stock and came back the next business day to install it. Matt finished up the AC work outside while Randy handled the furnace work inside along with a new thermostat. Randy was also great to work with and did the final walk through of how the units operate, answering all questions and providing the info I needed. I wouldn’t hesitate to have MM Comfort back to do this type again. Very highly recommended!
Robert Duncan23:07 23 Mar 21MM Comfort Systems replaced my old furnace with a new one. What a great team — professional, caring, and responsive, including the technicians and the administrative staff. Despite unexpected problems (not their fault), which required repeated visits, they worked hard to make sure the installation was successful. I would recommend this company to anyone.
Diane Campbell18:42 22 Mar 21We had a new furnace installed as well as an air conditioner. Mikel and Ina did a great job! The price was the best we found and between the scheduler on the phone, the guy (Steven) who came out to give us an estimate, and Mikel and Ina, who did the installations, everyone was so knowledgeable and personable. We would definitely recommend them!
Anya Hartshorn23:58 20 Mar 21Juan was the first technician to arrive at my residence. He was respectful and on time. He explained the process of replacement and how to use the system for some cooling in the summer even without a heat pump. Ruslan joined him a short time after and he installed a gas line connection and duct piece that they included in the fixed price.
Greg Guillen17:41 17 Mar 21The team at MM Comfort Systems did a great job with our AC install. Todd did a thorough assessment of our home to determine our AC needs and was great at explaining the assessment process. Our install team, Chris & Andrew did a great job at the installation and were very efficient. Overall, we were happy with our interaction with MM Comfort Systems!
Dan Ngo17:28 17 Mar 21Replaced an older gas furnace and ran a new thermostat wire. Very professional and quick. Entire swap out was under 4 hours. The installation team, Drew and Lamont, were very efficient and used drop cloths where necessary for the inside work. I highly recommend them.
Robert Hurd17:37 15 Mar 21Mikel & Ina did a fantastic job installing A/C. Highly recommend their professionalism and responsiveness. They came on time and completed on time. Thanks for all the good quality work you have done.
K V02:41 12 Mar 21Drew and his partner were professional, courteous, and walked me through each significant change to install AC to my existing unit. They made sure I was satisfied with the work before the left and without question I was.
Nicholas DeGaetani05:36 04 Mar 21The two installers, Mikey & Lucas were professional and knowledgeable. They got right to work and finished the same day. The installation looks good and everything worked fine. we passed inspections with n corrections needed.I feel we got a great deal and am looking forward to a little global warming this summer.
Tom Johnson02:36 27 Feb 21Installed a new furnace, very fast and efficient (heat wasn’t out for long). Very low impact in the house and cleaned up fully when done. Great Job!
Joseph Bisacca00:05 26 Feb 21MM Comfort Systems provided excellent service installing an Electric Heater, HP and A/C, which replaced our oil furnace. Tristan came out to give us a bid on the work. He was thorough, knowledgeable and patient explaining what needed to be done, and answered all my questions. Many thanks to Joe and Ruslan for the excellent installation they completed expediently, which passed inspection with no problem. Justin did the work on our electric panel, even suggesting a clever short cut from the outside of our home to our indoor furnace room. He was in and out in no time at all. Joe and Ruslan were friendly, informative and very polite. They cleaned up everything, so that it was undetectable that any work had been done to our home. Communicating with their office was a breeze. Desiree and Hannah were available to answer questions and provide assistance when needed. Very friendly and helpful. Great company, great employees, great job and reasonable cost. Should the need arise, I would hire them again.Cathy Kennedy2/22/21
Cathy Kennedy15:35 22 Feb 21Mike and Ina were excellent. The conduit work was discrete and cooling unit was set up very well.Todd was very helpful from quoting through installation. The front office team has been helpful and responsive too.I feel like we have finally found a great heating and cooling company to work with.
Leah Morgan16:57 20 Feb 21Had MM install new Furnace and AC and they did a great job through the entire process. Adam & Mark the installers did a great and clean job. Would recommend the folks.
Ken Mallit21:43 19 Feb 21My heating system needed a repair. MM was able to send a technician the same morning I called them. The technician sent me an email to inform me that he was on his way to my house. When he arrived, the technician quickly made a diagnosis and ordered the part needed for the repair using a mobile device. MM called me the next day and told me the part can be installed the following day. The technician arrived in the morning during the scheduled hours and installed the new part without any problems.Overall, MM was very responsive, professional, efficient, and easy to work with. They fixed my heating system in 3 days. I got heat back before the big snow storms hit the Seattle area. I am very appreciative of the service they provided.
Simon Liu01:12 17 Feb 21Zach and Randall did a good job install new furnace and thermostat, show up on time and get the job done, we are happy with their professionalism, highly recommended!
allen ho07:04 14 Feb 21Fantastic maintenance and repair people. Best prices, and just plain good people. I have had their help for years and they always go the extra mile.
ron george15:40 13 Feb 21MM are AWESOME!!!.We recently decided to add an AC through Costco. From the representative I spoke with at Costco (Christy), to the end with Ryan and Tyler being our installers, everyone was courteous, professional and very friendly. The company responded quickly and the appointment was scheduled right away. The sales representative, Bob H. was very nice and explained the process in easy to understand terms, helping us to make the right decision. The office staff (Desiree, Jenah and Hannah) were excellent in their communication and on-point with permitting, warranties and other documents.Everyone that came to our house was very respectful of the property. Ryan and Tyler worked around the existing features and after the install left everything spotless. They were great on the final walk-around and explained the equipment and features.A great example of businesses adapting to COVID- everyone always wore masks, distanced, and were very safe. Very pleased and would not hesitate to do business with, or recommend MM Comfort Systems.
Corina Marcus-Siteanu00:37 09 Feb 21Joe and Ruslan did a great professional job, and I was very impressed with their work ethic and timeliness in completing the work. Well done guys !
George Maffeo19:52 08 Feb 21Recently needed a new furnace and MM Comfort was recommended to me by a trusted friend. Andrew and Chris were fantastic! They were professional, respectful and did a great job! would definitely recommend them to anyone.

George Maffeo04:14 05 Feb 21MM Comfort Systems was the last one out of five contractors that I evaluated before making the decision on heating furnace replacement for my home in mid-Jan 2021. Long story short, I am highly satisfied (to date) that I have chosen MM as my contractor. From start (sales) to finish (product support/follow up), my experience with MM was outstanding overall. Sales rep (Tristan) was super-responsive and up front while Jenah (office) seamlessly tracked all the progress to seal the deal.My installer, Dan, was flat out fantastic and professional. He was on time for the installation and was courteous at all times when I asked questions along the way. He also ensured to leave the premise without any trace.I will revisit this review if anything new comes up that is worth mentioning, but based on what I have experienced thus far, I would highly recommend.
Alex Kim18:52 02 Feb 21Great company, and associates were very professional, courtesy and helpful. I would definitely work with them again.
Carl Banks17:40 01 Feb 21Worked with MM Comfort to determine our options for installing AC and also improving comfort inside our home. Jason was able to go over every possibility with us and quickly schedule us for an install. Team was able to quickly and efficiently work on our home and get done earlier than expected!I would recommend these folks, they are completely on the ball and have been amazing to work with!

Anthony Cheng21:22 29 Jan 21The installers did an awesome job removing my old furnace and putting in my new system. Everyone was great to work with. Thanks guys!
Ryan Merrifield01:48 29 Jan 21This install was part of the Costco and Lennox promotional deal going on. I had MM comfort systems come to my house and install AC onto my preexisting heating system. The salesman quoted them only needing one day of work, but once the actual installers got there the installers quickly let me know it will definitely be two days because the large volume of work required. They needed to move my furnace and install the AC unit which they were not prepared for because in my homes particular situation it was not as simple as most other homes. My furnace is wedged in the attic (3rd floor) and totally surrounded by all the ducting. I figured it was a 2 day job so I wasn’t surprised when the installers said they needed 2 days.The electrician was there the first day and he was in and out. Running the new circuit from my breaker box was pretty straight forward. That left the 2 other installers Drew and Lamont. These guys really knocked it out of the park. They worked solidly for 2 whole days, 1 of which was spent crammed in my tiny attic covered in fiberglass insulation. They discovered a bunch of problems with my furnace and were able to fix everything on the spot. These 2 gentlemen are the perfect example of how the blue collar workers carry these companies on their back. These guys showed up, handled all the paperwork, explained permitting, warranties, installed the new AC, redid my furnace, took me through every step of the process because I was curious, AND always stayed professional. I can’t praise these 2 guys enough. DREW AND LAMONT DESERVE A RAISE!When everything was said and done. I paid MM to install air conditioning in my house and they did that. And in the process of AC install they also fixed my furnace and now my house feels so much better and comfortable. The price quoted had a little sticker shock but after digesting the fact that I got 15% cash back from Costco and was able to put the install on a credit card and got another 1% cash back I felt good about going forward with the purchase. Despite all the road blocks encountered and the additional work needed, MM stood by their quote. The amount of money i’ll save going forward is unknown, but they rewired my furnace so its not constantly blowing 2nd stage air and pulling a ton of amps and now in the summer I won’t be running 3 portable AC units. I feel it was a good investment for our home and was executed by a great team of guys.
Jacob Suppa16:45 28 Jan 21Joe & Ruslan were absolutely wonderful people, they came out and were quick and diligent about the install of my ac and new furnace. I would highly recommend that if you are in the need of a new system that you give them a call and ask for Joe & Ruslan. Bob who was our consultation guide came out and was also very thorough on what we could expect from our system as well as concerns for our old one. He was neither pushy nor impatient with us as we debated on what to do.
Andrew Scarbrough18:19 22 Jan 21The team was extremely responsive to help us address our urgent need for a new furnace. Steve was able to get out to provide us a quote within a couple of hours of our initial call and the team was able to get the furnace installed next morning!! All in all it was less than 24 hrs from initial call to fully installed equipment. Mikey and Lucas on the install team were prompt, courteous, and quick! Appreciate the check-in and coordination from Hannah on the service team. Great customer service. Thank you.
Collin Clark23:32 15 Jan 21MM comfort was very fast, professional and well priced
Brian Pintler15:19 11 Jan 21Andrew and Chris were so nice and polite. They were right on time, walked me through the process, and reviewed how it would look. Then after installation they cleaned everything up and gave me instructions on how to use the system. The electricians arrived and did their part and everyone was out in 4 hours. Thanks!

MM comfort is definitely one of the top and most popular HVAC contractors in greater Seattle area. I waited a few weeks to get the system installed but worth it! Adam and Marc did a great job making sure the system is installed and working properly. They even helped to install the Nest thermostat that I purchased separately and shown me how to use it.Jamie Yu19:52 04 Aug 21Great experience, great responsiveness! Jason answered all our many questions before install and worked with us to get exactly what we wanted/needed lined up. Tom and Jordan were friendly and professional installers and worked quickly and efficiently. We’ve been enjoying our new AC system greatly!anne black22:05 30 Jul 21Dan, Zach and the entire team at MM comfort systems are amazing. We purchased and installed a heat pump for our split level home. Dan and Zach were able to plumb the system into the house and fish it through the ceiling to conceal much of the piping. Impressive. They were here all day working hard to get our system up and running the Friday before the heat dome/wave hit. The level of care, effort and explanation was fantastic. I highly recommend this company for all your HVAC needs.Robert Williams04:08 29 Jul 21From the initial bid the to installation, using MM was easy. I’ve used several contractors as I’ve been updating our house over the last few years and they were one of the few that was fair, on time, and professional.Brad Mott19:02 27 Jul 21Using MM Comfort Systems to select and install our AC unit was the best experience. From the consultation and estimate with Vince to the installation with Joe & Joseph, everything was seamless. Everyone was so nice, so helpful, responsive–all the things you want when working with a company. We will definitely be using them again when we get a generator or any other services!Keri Ferguson-Smith03:20 23 Jul 21We were impressed with the overall service and timeliness of everyone in the organization!Arlene Hanson03:14 20 Jul 21Bryan Solemsaas20:29 19 Jul 21Drew and Rock did great job explaining the process in advance and providing updates. The work they did looks very neat and professional. Clean too. Everything works to our satisfactions. Thanks!Dan Kissin20:21 14 Jul 21Beautiful install. We love the system. Both inside and outside units look great. Mechanical crew cleaned everything up and it looks great. Electrical crew installed wiring as requested through unfinished basement. Only issue was electrical cleanup. Spent about an hour vacuuming up shavings from the holes they had to put through joists.Lee Winstrom19:29 12 Jul 21From start to finish the process was very seamless. The consultant, Steve Vick, was great to work with and very knowledgeable. The installers (Sam, Joseph, and Antonio) were courteous and very mindful of our home and took proper care to ensure our home was in better condition than when they got there. Upon completion they gave a thorough walk through of the system and took the time to answer all of my questions in extra detail. Will definitely recommend MM Comfort Systems to anyone looking for Furnace/AC help!Sterling Nelson17:27 09 Jul 21Installer came at 8am and finished work almost at 6pm. Great work on installation and clean-up but the only problem I had was “measure 2x and cut once” was not followed in looking for wire connection so several holes were cut on my garage ceiling that I have to repair. Office helps you file for rebates and make appts for inspection.Teresa Brown23:17 07 Jul 21On the hottest day ever Sam & Russ put in extra effort to get our new A/C installed. It was grueling but they worked tirelessly to get the system installed and did so in a professional manner. The unit looks great and has functioned perfectly. The time they spent dialing it in after the install demonstrated their professional rigor.I collected 10 bids before going with MM Comfort Systems. They weren’t the lowest bid but the confidence they conveyed during the bid process carried through to the install. I would definitely recommend them!L D K03:26 07 Jul 21MM Comfort installed our central AC for us. The entire process was enjoyable and painless, starting from Bob who did the initial consulting, to Mikel & Ina who did the installation. Bob was able to identify an unused breaker in our electric panel and helped us avoid a panel replacement. For the installation, Mikel & Ina were very professional where they made sure to keep us well informed in the process and were able to finish in a very timely manner. In addition, their knowledge and expertise really helped to avoid necessary steps. Overall a very satisfying experience, and would recommend indeed.David Liu07:28 05 Jul 21Sam, Matt, and Antonio installed our AC. They were friendly and kept us informed. They ran into some unexpected issues but they put in the extra effort and time to get it installed.Gregg Hirata03:16 04 Jul 21From start to finish, MM Comfort Systems did a fantastic job. Jason the Sales consultant answered every question and accurately described the process. Joe and Joseph the install technicians were respectiful, courteous and left our home clean.The whole experience was pleasant and truly a value. I cannot believe I waited this long to have A/C installed.Jeff Daub18:02 02 Jul 21We had one minor issue with what the salesman said could happen vs what the installers were able to do. This did delay our installation by 1 month. It is now installed and is running and cooling excellent. We have a tri-level and were concerned with even cooling, but its cooling all levels great. The installers were very professional, they called prior to arrival, were knowledgeable, and cleaned up all areas they worked. The final installation is very professional in appearance and works as promised. I would recommend to my friends and family. The only reason I gave four stars was the delay of installation due to the issue with what the salesman said and what the installers could do. We love the cool air!Carol Allread20:44 01 Jul 21We decided to purchase AC for our home this year via Costco. Vince came out to provide us with a quote and walk us through all of the available options we had in terms of where we could locate the unit, what types of units were available, and other recommended products and services. He gave us clear answers to our questions and didn’t try to upsell us to something we didn’t need – we were thoroughly informed and able to make choices that were best for us.Sam & Antonio did the install. They were quick and professional and answered all of the questions I had about how to operate the unit, what the status of the work was, etc.I deducted one star because there was a part that was defective (not their fault) and Sam informed us that the office would reach out to us after they left to schedule someone to come by and replace it. I ended up having to call them after a business day and a half (plus two weekend days) of awaiting further information. I assume they were probably VERY busy but knowing that the inspections were pending had me really anxious.. With that said, this was incredibly minor – just a small point of improvement.When I connected with Hannah in the office by phone, she was incredibly professional, quickly got a technician out to finish the job, and even took the time to register our unit for us.Everything has been working flawlessly the last month and kept our house nice and cool, even during the record breaking heat!I would highly recommend MM Comfort Systems! Thank you, team, for your hard work in helping us join the COOL KIDS on the block this year 🙂Melissa D02:39 01 Jul 21The MM crew showed up on time and got right to work. They kept me informed and explored the best possible solution for my AC installation. They were all friendly, courteous, and professional. I love my new AC!!Chris Cooper22:17 30 Jun 21MM comfort system did my A/C unit installation in a professional manner .Technicians Travin and Antonio did awesome job.Jobi Paul19:34 26 Jun 21Our install was back in February but wanted to make sure to leave a review for Joe and Ruslan at MM Comfort Systems. We liked how fast they completed the install. They stayed in constant communication and even alerted us to the water heater leak which was completely separate from their job. Even found a bucket in our garage and placed it at the leak site. This saved us a lot of money and headache in the long run. Cannot express our gratitude enough.Erica S21:08 25 Jun 21Tom and Jordan did a fantastic job with the install, and made sure to clarify with me before any subjective decisions are made. Very happy with the work.Jacky Yip04:50 25 Jun 21Process went great Sam and Antonio answered all our questions and did a great job.Richard Brigman20:50 24 Jun 21The whole crew was awesome. They where very professional and clearly explained everything that was going to happen showed me everything after they finished and cleaned up after themselves.Todd Knopp13:06 21 Jun 21Great service! Dan & Zach are awesome, they also helped move the plants!Lasifu Ta19:36 18 Jun 21Very easy installation of a new gas furnace and new to the house AC. Tyler & Ryan were very polite and COVID aware, they took care of everything and walked me through how to operate everything. The new system passed the city’s inspection on the first visit.Eileen Burns Caparoso18:43 13 Jun 21The install technicians, Sales team and customer service did an exceptional Job. They were very courteous, knowledgeable. They did not disrupt our house during their installation at all. They clearly explained everything about the use of our new AC installation. I highly recommend MM comfort system.Michael Maddox15:39 12 Jun 21I would recommend MM Comfort Systems to those looking to install AC or a new furnace. The installers, Sam & Ruslan were efficient, clean and knowledgeable, in and out in two days, one day for furnace replacement and one day for new AC. From start to finish MM employees were polite and efficient, knew the correct installation for new electrical, heating and AC. All passed inspection.George Jonson12:38 10 Jun 21We found the worst situation possible when having a different company come out to quote repairs on a system we inherited with the purchase of our home. The furnace and AC were broken and red tagged, that other company quoted a lower quality system replacement at 5K more than MM. Jason was a great no pressure salesman who gave good recommendations on system selection based on needs and budget. We agreed on the price and got it scheduled ASAP. Sam and Antonio arrived to our house right at 8am when the noise ordinance shuts down for the morning and proceeded to uninstall the ratnest of an old system and cleaned up the install and put in the new Carrier system which has brought us much comfort and sleep for the last week. THANK YOU THANK YOU THANK YOU as my 3 year old would say.Colby Crouch21:08 09 Jun 21Sam & Antonio were professional and friendly. They left no mess. They cleaned up. They were actually very good with the install and took off shoes when entering the house. Highly recommend!Mai Mai05:02 04 Jun 21Our installers Travin & Kaelen were very friendly and polite and considerate of the home environment. They did a clean work and we really appreciate their efforts. They answered to all the questions and gave wonderful suggestions that were very useful for the whole installation procedure. They did a great job! Overall the experience was good and would definitely recommend Travin & Kaelen working for MM comfort systerm.Sai Priya Kumar21:25 03 Jun 21Tom and Jordan showed up early and were super professional. Even when the original plans didn’t work out as we thought they might, they were happy to just adapt and do what needed to be done instead. All in all I’m super happy with their work and glad I went with MM Comfort Systems. I’ll definitely be using them again for any work that they service.Keith Horton06:06 30 May 21Randy and Matt were efficient in replacing my old heat pump with a new system. There was a small issue that had to be worked, but MM Comfort Systems diligently worked the issue until resolved (thanks Shaun!).Kevin Sandal18:18 27 May 21MM Comfort Systems installed a heat pump HVAC/air scrubber along with replacing an aging electrical panel and we couldn’t be more pleased with the end result. They did not sub-contract out any of the work and made sure we were 100% satisfied with the final product. Tom & Jordan were very professional and they didn’t mind me being curious and nerdy about “how things work”.When drilling for the thermostat wire, the in-ceiling power line to the water heater was accidentally damaged (just bad luck) and when we realized the next day that we had no hot water, they sent out a team ASAP who quickly identified the cause and made it right.I would not hesitate to recommend MM Comfort Systems!John Bartlett17:11 21 May 21Thank you the MM Comfort Systems team for providing great customer service from beginning to end. Todd our sales rep was friendly, knowledgeable, responsive and walked us through each step. The team the installed our electrical panel was quick, knowledgeable and professional. Our installers Tom and Jordan were on time, super clean, friendly, professional and kept us up to date on their progress throughout the day. The end result was amazing clean air in our home. We are very grateful. There was one hiccup with the install that showed how committed they are to doing the job right. There service department was quick to schedule a team to come back out within hours. We are so excited to start this long term relationship with MM Comfort. Finally, thank you to Sherry in the accounting department. She too was great at communicating. It takes a team to provide great customer service. Thank you all for changing our lives with your amazing product.Jessica Bartlett04:08 21 May 21Matt & Randy executed a professional install for a new furnace and whole-house AC system. Their attention to detail was evident from the precise installation of the furnace in a tight space (1/4″ clearance) to the caulking around the gaps between piping and walls. MM Systems coordinated the whole job, including permitting and product registration. Highly recommended.Mihai Aldea22:44 20 May 21I had an HVAC mini split installed and Joe,Joe, Mike and Mike’s associate (sorry I didn’t get his name) were on time and worked efficiently and got the unit installed within 5 hours. They cleaned it after themselves and were very helpful and friendly. A great experienceLinda Paramore19:19 20 May 21We are a long time customer of MM Comfort Systems.We have had a heat pump system for over 40 years; but it needed replacement. Installation was by Adam and Marc who were efficient and thorough. There were no short cuts and clean up was superb. The electrical inspector just completed his inspection and said the installation was totally up to code.John Gentry18:14 20 May 21The whole project is very smooth. Very effective communications keep me updated from the sales stage (Steven Vick) all the way through the finish line of the project. The installers Sam & Antonio are very customer-oriented and friendly. they kept me updated with the progress of the installation. Also important is that I can see there is a strong team to support the whole project, and that’s why I chose MM Comfort.Alexander Wang05:37 20 May 21I used MM comfort Systems to install AC in my house. They reused the existing ductwork, added the heat pump, and replaced the furnace. The whole process from initial contact to install was only 2.5 weeks. Adam and Mark were very knowledgeable and professional. They got brought up anything that wasn’t expected and offered options for solutions. Great crew, would hire again.Alex Lamb22:42 19 May 21Mikel and Ina installed a mini split for me. They arrived on time and were very professional. They both did a great job inside and out.Erlinda Jimenez04:39 15 May 21I was very satisfied with the new furnace, it controls the heat and sound very well. It was well done.Irene Lee18:39 12 May 21This is the second time I’ve used this company to install furnace/central cooling and they were great both times. The employees were friendly and enjoyable to chat with and very informative when I had questions or concerns. Rod the sales guy is awesome!Holly Fuerte15:52 03 May 21Mike and Jason Installed our Lenox Furnace. They were courteous, skilled and informative. The whole experience was very positive. Mike and Jason did a great installation and totally gave us all the info we needed.David Kirdahy02:51 01 May 21From the initial meeting with Jason to get a bid on my project to the furnace and AC installation by Chris and Kaelen, working with MM Comfort Systems was a fantastic experience.Jason and the MM office staff answered the million questions I sent their way quickly, patiently, and accurately.Chris and Kaelen then worked extremely hard to install all the components, and the place was cleaner when they left than when they got there. They arranged all the permits and inspections, so the project could not have been easier from my end. I am thrilled with the Carrier hardware that was installed.Phil Hutchinson17:53 28 Apr 21Tom & Jordan were very professional, friendly and their work looks great. The rest of the team at MM Comfort Systems were very helpful as well.Graham Watts22:18 21 Apr 21Responsive. Great quality product. Installers Drew and Lamont were on time, efficient, wore masks and left the area clean and tidy.Carina Moravec02:14 21 Apr 21Sam and Juan, with MM Comfort, were on time and professional. They got it done in reasonable time, packed up, and we were good to go. A new thermostat was necessary and was installed, at no added cost. The warranty is great, and we have the added advantages of the Costco guarantees.Philip Shack22:10 15 Apr 21Jessica Wyckoff19:20 15 Apr 21My quote was with Tristan. He answered all my questions and guided me to the best option for my family. Matt & Randy did my install. They were great. My Lennox condenser in the bottom of my furnace broke during the pressure test and let refrigerant throughout my house which was unfortunate, but nothing installers could have changed. They had to come back 2 days later, replaced the condenser, cleared the line and installed new refrigerant. All is working great after that. I’m happy with my choice with MM Comfort Systems.Mr White06:32 14 Apr 21The price was great. We went through Costco and MM is who contacted us for the quote. The quote was fast and affordable and the installers Drew and Lamont were friendly and communicated with me throughout the process.Jennifer Canter19:27 13 Apr 21Travin & Kaelen were professional, friendly and speedy! Our AC was installed in one day, and upon completion, everything was explained to us in plain English. The whole procedure was minimally invasive and overall really well done. Thanks!Sidney Field18:09 13 Apr 21They followed up until they were able to get the heat pump system fully operational. Very pleased.Michael Mulvihill18:21 10 Apr 21Caden Nguyen22:34 09 Apr 21To To21:58 09 Apr 21I used MM Comfort systems to replace our Furnace and we couldn’t have been happier with the technicians that installed it. They were professional and made sure install went as smooth as possible. The sales team missed something so the techs had to be creative to solve it all while making sure I had an A+ experience. They also arranged inspection which saved me time from navigating that. Thanks and would buy from them again.Johnny Blair19:43 09 Apr 21I love our new furnace, it’s so quiet and I noticed within 2 days how the air filter system made the air feel so much cleaner. With two big dogs in the house it really made a difference and keeps the dust down. I can’t wait to try the A/C this summer. The installers were great, helpful and friendly.Thank you everyone.Luanne Schreibe & Wayne MattaWayne Matta18:52 09 Apr 21Professional and friendly service. Travin and Kaelen were outstanding 🙂Sunny Heinrichs17:05 09 Apr 21We cannot say enough good things about MM Comfort Systems! We had a unique situation, and needed to have our furnace removed in order to access and repair a leak in our foundation. We had reached out to MM Comfort Systems to coordinate our furnace removal a few months in advance for that project. This made me nervous because the timing was not flexible, but MM was extremely communicative and arrived right on time the day that they were scheduled to come out.We were also curious about adding an AC unit to the house at the same time of having our furnace work done, and asked to schedule a consult. Bob came out to give us a quote and he was thorough, friendly, and did not pressure us at all. Well, he quoted us such a fantastic price, we decided to have an AC unit installed as well. When the day came to remove our furnace and install our AC, Joe and Dan could have not been friendlier, more courteous, or more professional. We were even offered a space heater because we would have to spend the weekend in our house without heat! Everything about our new AC unit was explained, and our furnace was efficiently removed and reinstalled good as new. On the office end, Hannah and Jenah were very friendly and knowledgable and made the permit process go very smoothly as well. We would not hesitate to recommend this company to our family and friends. Thank you for a wonderful experience MM Comfort Systems!Audrey McGill20:50 08 Apr 21We had MM Comfort Systems replace our 20+ year old gas furnace with a Carrier Performance 96% AFUE gas furnace.After getting quotes from 4 other HVAC vendors, we opted to go with MM Comfort Systems — their prices were reasonable, they had good reviews and their work included a 5-year “peace of mind” guarantee.Tristan, who came to do the estimate, was friendly, knowledgeable, patient and the very professional, and Zack who was part of the 2-person installation team, was the same (our furnace was installed in 5-6 hours, and we appreciated the fact that the guys cleaned up afterwards). I accidentally turned off the furnace after the installers left and 1-2 hours later, we had no heat and the thermostat was dark. I called MM and within 30 mins, Zack called back to help troubleshoot remotely (and was good natured about my faux pas). That’s the Good.The Bad:1. The other installer, who was also friendly, didn’t wear his mask all the time, and when he did, often had his mask below his nose.2. On Saturday, 4 days post-installation, I opened the closet to check on the furnace and found water on the floor. I called MM’s main line, left a voice mail; also called the CEO’s direct # but his mailbox was full. Couldn’t find a 24/7 phone # to call even though their web site refers to one. On Sunday, after replacing 4 towels that we’d placed on the closet floor to absorb the leaks, I emailed MM to ask them to send someone out ASAP.UPDATEMM Comfort Systems called first thing Monday morning and had someone over to fix the leak within hours, so I’ve changed my rating accordingly.Fiona Lee15:26 06 Apr 21Bitewa Wasse03:35 01 Apr 21The team from MM Comfort Systems came out to install a Lennox AC unit and they did an excellent job. They arrived on time and Matt walked me through what needed to be done, patiently and thoroughly answering a couple questions I had. Work was done efficiently and expertly. They discovered our furnace had at some point developed a cracked heat exchanger and needed to be replaced, which was unfortunate but unavoidable. I really appreciated Matt showing me exactly where the furnace was cracked and explaining the issue. MM had a new Lennox furnace in stock and came back the next business day to install it. Matt finished up the AC work outside while Randy handled the furnace work inside along with a new thermostat. Randy was also great to work with and did the final walk through of how the units operate, answering all questions and providing the info I needed. I wouldn’t hesitate to have MM Comfort back to do this type again. Very highly recommended!Robert Duncan23:07 23 Mar 21MM Comfort Systems replaced my old furnace with a new one. What a great team — professional, caring, and responsive, including the technicians and the administrative staff. Despite unexpected problems (not their fault), which required repeated visits, they worked hard to make sure the installation was successful. I would recommend this company to anyone.Diane Campbell18:42 22 Mar 21We had a new furnace installed as well as an air conditioner. Mikel and Ina did a great job! The price was the best we found and between the scheduler on the phone, the guy (Steven) who came out to give us an estimate, and Mikel and Ina, who did the installations, everyone was so knowledgeable and personable. We would definitely recommend them!Anya Hartshorn23:58 20 Mar 21Juan was the first technician to arrive at my residence. He was respectful and on time. He explained the process of replacement and how to use the system for some cooling in the summer even without a heat pump.

Very low impact in the house and cleaned up fully when done. Great Job!Joseph Bisacca00:05 26 Feb 21MM Comfort Systems provided excellent service installing an Electric Heater, HP and A/C, which replaced our oil furnace. Tristan came out to give us a bid on the work. He was thorough, knowledgeable and patient explaining what needed to be done, and answered all my questions. Many thanks to Joe and Ruslan for the excellent installation they completed expediently, which passed inspection with no problem. Justin did the work on our electric panel, even suggesting a clever short cut from the outside of our home to our indoor furnace room. He was in and out in no time at all. Joe and Ruslan were friendly, informative and very polite. They cleaned up everything, so that it was undetectable that any work had been done to our home. Communicating with their office was a breeze. Desiree and Hannah were available to answer questions and provide assistance when needed. Very friendly and helpful. Great company, great employees, great job and reasonable cost. Should the need arise, I would hire them again.Cathy Kennedy2/22/21Cathy Kennedy15:35 22 Feb 21Mike and Ina were excellent.

Adam & Mark the installers did a great and clean job. Would recommend the folks.Ken Mallit21:43 19 Feb 21My heating system needed a repair. MM was able to send a technician the same morning I called them. The technician sent me an email to inform me that he was on his way to my house. When he arrived, the technician quickly made a diagnosis and ordered the part needed for the repair using a mobile device. MM called me the next day and told me the part can be installed the following day. The technician arrived in the morning during the scheduled hours and installed the new part without any problems.Overall, MM was very responsive, professional, efficient, and easy to work with. They fixed my heating system in 3 days. I got heat back before the big snow storms hit the Seattle area. I am very appreciative of the service they provided.Simon Liu01:12 17 Feb 21Zach and Randall did a good job install new furnace and thermostat, show up on time and get the job done, we are happy with their professionalism, highly recommended!allen ho07:04 14 Feb 21Fantastic maintenance and repair people. Best prices, and just plain good people. I have had their help for years and they always go the extra mile.ron george15:40 13 Feb 21MM are AWESOME!!!.We recently decided to add an AC through Costco. From the representative I spoke with at Costco (Christy), to the end with Ryan and Tyler being our installers, everyone was courteous, professional and very friendly. The company responded quickly and the appointment was scheduled right away. The sales representative, Bob H. was very nice and explained the process in easy to understand terms, helping us to make the right decision. The office staff (Desiree, Jenah and Hannah) were excellent in their communication and on-point with permitting, warranties and other documents.Everyone that came to our house was very respectful of the property. Ryan and Tyler worked around the existing features and after the install left everything spotless. They were great on the final walk-around and explained the equipment and features.A great example of businesses adapting to COVID- everyone always wore masks, distanced, and were very safe. Very pleased and would not hesitate to do business with, or recommend MM Comfort Systems.Corina Marcus-Siteanu00:37 09 Feb 21Joe and Ruslan did a great professional job, and I was very impressed with their work ethic and timeliness in completing the work. Well done guys !George Maffeo19:52 08 Feb 21Recently needed a new furnace and MM Comfort was recommended to me by a trusted friend. Andrew and Chris were fantastic! They were professional, respectful and did a great job! would definitely recommend them to anyone.Dominique DeVoll01:18 08 Feb 21Shelly Sadettanh16:31 05 Feb 21George Maffeo04:14 05 Feb 21MM Comfort Systems was the last one out of five contractors that I evaluated before making the decision on heating furnace replacement for my home in mid-Jan 2021. Long story short, I am highly satisfied (to date) that I have chosen MM as my contractor. From start (sales) to finish (product support/follow up), my experience with MM was outstanding overall. Sales rep (Tristan) was super-responsive and up front while Jenah (office) seamlessly tracked all the progress to seal the deal.My installer, Dan, was flat out fantastic and professional. He was on time for the installation and was courteous at all times when I asked questions along the way. He also ensured to leave the premise without any trace.I will revisit this review if anything new comes up that is worth mentioning, but based on what I have experienced thus far, I would highly recommend.Alex Kim18:52 02 Feb 21Great company, and associates were very professional, courtesy and helpful. I would definitely work with them again.Carl Banks17:40 01 Feb 21Worked with MM Comfort to determine our options for installing AC and also improving comfort inside our home. Jason was able to go over every possibility with us and quickly schedule us for an install. Team was able to quickly and efficiently work on our home and get done earlier than expected!I would recommend these folks, they are completely on the ball and have been amazing to work with!Mark Passovoy02:47 01 Feb 21Anthony Cheng21:22 29 Jan 21The installers did an awesome job removing my old furnace and putting in my new system. Everyone was great to work with. Thanks guys!Ryan Merrifield01:48 29 Jan 21This install was part of the Costco and Lennox promotional deal going on. I had MM comfort systems come to my house and install AC onto my preexisting heating system. The salesman quoted them only needing one day of work, but once the actual installers got there the installers quickly let me know it will definitely be two days because the large volume of work required. They needed to move my furnace and install the AC unit which they were not prepared for because in my homes particular situation it was not as simple as most other homes. My furnace is wedged in the attic (3rd floor) and totally surrounded by all the ducting. I figured it was a 2 day job so I wasn’t surprised when the installers said they needed 2 days.The electrician was there the first day and he was in and out. Running the new circuit from my breaker box was pretty straight forward. That left the 2 other installers Drew and Lamont. These guys really knocked it out of the park. They worked solidly for 2 whole days, 1 of which was spent crammed in my tiny attic covered in fiberglass insulation. They discovered a bunch of problems with my furnace and were able to fix everything on the spot. These 2 gentlemen are the perfect example of how the blue collar workers carry these companies on their back. These guys showed up, handled all the paperwork, explained permitting, warranties, installed the new AC, redid my furnace, took me through every step of the process because I was curious, AND always stayed professional. I can’t praise these 2 guys enough. DREW AND LAMONT DESERVE A RAISE!When everything was said and done. I paid MM to install air conditioning in my house and they did that. And in the process of AC install they also fixed my furnace and now my house feels so much better and comfortable. The price quoted had a little sticker shock but after digesting the fact that I got 15% cash back from Costco and was able to put the install on a credit card and got another 1% cash back I felt good about going forward with the purchase. Despite all the road blocks encountered and the additional work needed, MM stood by their quote. The amount of money i’ll save going forward is unknown, but they rewired my furnace so its not constantly blowing 2nd stage air and pulling a ton of amps and now in the summer I won’t be running 3 portable AC units. I feel it was a good investment for our home and was executed by a great team of guys.Jacob Suppa16:45 28 Jan 21Joe & Ruslan were absolutely wonderful people, they came out and were quick and diligent about the install of my ac and new furnace. I would highly recommend that if you are in the need of a new system that you give them a call and ask for Joe & Ruslan. Bob who was our consultation guide came out and was also very thorough on what we could expect from our system as well as concerns for our old one. He was neither pushy nor impatient with us as we debated on what to do.Andrew Scarbrough18:19 22 Jan 21The team was extremely responsive to help us address our urgent need for a new furnace. Steve was able to get out to provide us a quote within a couple of hours of our initial call and the team was able to get the furnace installed next morning!! All in all it was less than 24 hrs from initial call to fully installed equipment. Mikey and Lucas on the install team were prompt, courteous, and quick! Appreciate the check-in and coordination from Hannah on the service team. Great customer service. Thank you.Collin Clark23:32 15 Jan 21MM comfort was very fast, professional and well pricedBrian Pintler15:19 11 Jan 21Andrew and Chris were so nice and polite. They were right on time, walked me through the process, and reviewed how it would look. Then after installation they cleaned everything up and gave me instructions on how to use the system. The electricians arrived and did their part and everyone was out in 4 hours. Thanks!Gayle Gray17:02 30 Dec 20Gregory Wakefield21:40 26 Dec 20installed a new AC unit. very clean and neat in their work. actually showed up at the time we were promised–that’s a surprise in this business. one note–they did not tighten a gas line connection and when we smelled gas later that day, we called them and their service man showed up at 9:00 pm on a Friday night. he was here for 1.5 hours making sure the leak was fixed. he was polite and answered all our questions. thanks for being so diligent!Judy Russell17:57 26 Dec 20Our Accreditations
