What our Customers are Saying!
Most recently, John and Manny completed installation of our replacement furnace and did so in a thorough, professional, and timely manner.

MM Comfort Systems installed a Mitsubishi ductless heat pump at my house recently. The house was originally built with hydronic heating, so the mini split is an addition and provides AC plus a second option for heating. Had a very good experience with MM. The salesman, Russel, was very professional. The installers, Sam and Antonio, did a really nice job on the install and the installation looks extremely tidy. I can't comment on the long term durability of the Mitsubishi at this point since I've only had it for a few weeks, but so far its performing very well.

Got nothing to say but the best interaction I’ve gotten from a contracting company. We went thru Costco to get a new gas furnace and ac setup. Drew, Jason, and Jeremy was my main crew who did the install. I had to work during most of the install but Drew always contacted me with any issues that came up and also let me decide where I wanted things to go. I thought that was very nice because most people would just do whatever that was easier for them to get the job done. I had a gas line installed to the meter also, I didn’t get to meet him nor the electrical guy but they both also did an amazing job.Update: forgot to mention that I had a hard time getting ahold of the sales department. Left atleast 3 Emails until I got a answer back. Wanted to add another product to my system but I’m waiting for a email response. The install crew were too notch. But the sales side and appointment side, not so great!

Our installers, Carlos and Carlos, Jr did an excellent job in doing both a furnace and an AC installation in the same day. They were very focused to get the job done so that we could get our heat for the cold night.

Fast, friendly service! Figured out our furnace wasn’t working during the first cold snap of the year, they still got us in fast and had great communication!

We have used this company for close to 8 years. They installed our Mitsubishi mini splits and also maintain them. Everyone has been professional. Prices are discussed prior to them showing up. Pricing is good. Allen was our technician today. He has worked with this company close to 30 years. Super knowledgeable and trustworthy. I highly recommend this company.

Maria and her team did a fantastic job of replacing our hvac duct work. They showed up on time and we’re very respectful of our home. They cleaned up their work so well, you would never have known they were there. I will recommend them to all my friends and family.

Geoff and the team at Sullivan did a fantastic job replacing our aging HVAC system. We had a complex system and the team assessed our needs and designed a great solution for our 2 story home. I got 4 bids and the Sullivan bid was by far the best design. The other companies just wanted to replace our system with the same. Design was 100% Execution was 100% Thanks Geoff and team.

Cool guys I dealt with today. They seem laid back and down to earth. I had an interview with them earlier today. Hopefully we can work something out.
