What our Customers are Saying!

We felt they were efficient, knew their job and communicated well. However not pleased with the final thermostat configuration. We paid for a wire pull to be able to use our Nest thermostat which has WiFi but we were told that the wire would not go through the wall. We were provided a Honeywell thermostat but we do not have the WiFi capability.

Upgraded to a new furnace and air conditioning system through Costco Home Services. The MM Comfort System installers, Lamont and Qushawan, did an outstanding job. They were on time, courteous and did a nice job of cleaning up after installation. The furnace and air conditioning units were installed on separate dates due to availability of equipment. A week after I received my estimate, my original furnace died. The folks at MM Comfort Systems moved my furnace installation up to that same week. I really appreciated their rapid response. The new furnace is much nicer than the old furnace and made the holidays really comfortable. I am looking forward to having air conditioning for the first time this summer in my home. It will be a welcome relief from last summer. If you need a new furnace or air conditioning system, call them first.

This company was great to work with installing our A/C from start to finish. Steve the rep was always available when we had a question and the installers, Ruslan and Dallas were professional, friendly and efficient. When we had to move the location of the AC unit at the last minute, Dallas jumped in and helped dig up a stubborn beast of a shrub. Installing the unit in the attic wasn't fun but they did it with humor and without complaint and they made sure everything was cleaned up before they left. Great follow up by Hannah handling the permits. We didn't have to do anything! Would highly recommend this company.

My previous furnace is broken, and MM comfort system assist me with a new Carrier Infinity Furnace with Infinity Thermostat. The installer Ruslan & Scott came during a cold day (thumbs up), are professional and courtesy during the installation process. The furnace has been setup perfectly. Throughout the process, the MM comfort system is very responsive in responding to my inquiry and request.

MM 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.

Our heat pump failed the night before the big heat wave back in late June. We were facing the prospect of having to search for a place to stay cool since all the HVAC companies we called gave us appointment times several days and even weeks away. We called Sullivan late Friday evening and they had a technician here Saturday morning and he fixed the heat pump in about 30 minutes. We needed a part and Arnold the technician had it in the truck! Go figure. Our external thermometer got up to 113 degrees two days later. I can't speak highly enough of this company. I can't imagine the misery and discomfort they saved us and possibly the death of my old dog from the heat. Thank you Sullivan Heating & Cooling.

Travis our service tech was friendly and knowledgeable, he explained everything he was doing and why. Fixed the problem and did not leave until he made sure everything was working correctly. Definitely will use Sullivan Heating and Cooling again in the future.

Sullivan installed our new heating system this year and worked with us so the thermostat settings are right. We have been so grateful during this time of hot temperatures we have the service. They do a great job!

My heat pump broke down unexpectedly the night before a record heat wave was expected. I called just about every HVAC company I could find and no one was willing to book an appointment for at least several days out. Most were several weeks. But Sullivan returned my after hours phone call within minutes and had a tech come to my house within a few hours and quickly made the repair. Their work was great, and their prices were fair. These guys are superheros and I can't recommend them highly enough.

I did some research into how heat pumps worked prior to calling for estimates. Two other companies came out before Sullivan, both lied to me. Sullivan was honest and followed through beautifully, my only regret is that I had forgot to get a bit of cash to tip the installation crew!
