The installers (Tyler & Ryan) were punctual, provided me with updates as they were performing the installation, and the quality of their work showed. They gave me an overview of how to operate the system before leaving as well. A++

On February 24 and February 25 of this year. MM Comfort Systems install a new gas furnace and an air-conditioning unit in my house. I am writing because I am beyond happy with my experience and the result. Matt came out, looked at my situation and explained the options I had for replacing my old gas furnace. I had had a different company come explain what my options were a few years back. That fellow tried to talk me into a very expensive furnace. I have a small house and do not need a big furnace with lots of bells and whistles. Matt was very honest and helpful, and I feel I made the correct choice for me. My communication with the company was professional and helpful. Joey and Alex, the installers, showed up right on time. They were very professional. Joey was the lead. He explained what they were going to do and why and made sure I was happy with the decisions. My old gas furnace that was replaced is in the basement was across the room from where the air-conditioning unit was. I have a very low ceiling. To attach the outside air-conditioning unit to the ducks, they had to find a way to connect the unit and not obstruct head room. They did a great job. The furnace is so quiet and efficient. I’m toasty warm. The thermostat they installed is very easy to use and has useful features that my old one didn’t have. Everything about the units was explained to me. Two inspections were required. MM paid for both and set them up for me. The process of getting and installing my new units was smooth and easy. I highly recommend this company! I am so pleased with what I got and how it all went! Thank you MM Comfort Systems.

MM Comfort Systems has been a joy to deal with, which had not been our experience with HVAC dealers previously. The back office staff is wonderful, responsive and efficient--obtaining initial estimates, scheduling the installation, arranging for inspections, etc. The installation was complicated and Sam and Antonio were professional and kept us informed as they resolved the various issues that arose. This is a class organization.

They product and the install process was just as I had been told it would be. The scheduling and payment process was flawless, including the Costco rebate. The cost was very reasonable and the installers, Randy and Clinton were exceptional. My health issues and concerns (an important aspect of my decision to purchase this unit in the first place) were taken into consideration from the very start. I was also impressed with their expertise and experience as they moved through the two-day installation process. They knew what they were doing, were unfazed by the seeming complexity of the install and knew a lot about relevant area building codes. They coordinated well with the electrician who provided a critical circuit to power the device and they paid attention to the aesthetic details of the final setup. They shared what their plans were for the install and why they had to do what they did. They also tested it all out for me, once done, to show me that it worked as intended. Clean-up was great too. Thanks for delivering as sold!

We are very happy with our experience with MM Comfort Systems. We appreciated our salesperson Russell who explained our options, as well as installers Mikel and Ina, who did a great job with the project.

We had MM Comfort Systems fix a plumbing pipe in our basement. We called multiple companies to get a bid and we’re going to have to wait weeks, but MM fit us in much sooner because of the severity of the issue and at a great rate. The technician Ryan was also great and finished the work quickly and correctly.

Replacement was emergent. It was a Friday morning before a long weekend. I contacted MM comfort systems and Greg Forsell, one of MM's Managers I think called me personally, moved less emergent appointments around and got a plumber to my home before 1 pm that same day. He pulled out our old/dead water heater and installed a new energy efficient one and we were back in business, water all mopped and hot water by early evening the same day. I gave a 4 to price because it was a spendy endeavor, but that is simply the cost of a new water heater and removing and replacing the old one. MM's charges were fair and reasonable. I have no complaints and highly recommend them. MM Comfort Systems also maintains our HVAC systems, keeping them running smoothly.
