Home Comfort Alliance - formerly MM Comfort Systems

Mike and Jason did a great job installing central AC. They showed up right on time and were accurate on how long the install would take. They answered all my questions and were very knowledgeable about the whole system. I would definitely recommend using them.

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.

We had a ductless heat and a/c system put into our townhouse. We are a middle unit and wanted units in rooms on the front and back of the house. This made it complicated but Drew and Lamont and their electrical team were absolutely wonderful to work with. They were great about communicating the process to me and were so patient and kind with my kids who were SOO curious about what they were doing and excited to see them working.

Business address is listed as Sumner, but called from a Redmond phone number and stated just to make the trip out to Sumner would be $295.00! (PLUS diagnostics and repair)

PS I did not request after hours service, only asked what a service call would cost.

Devin and Michael were very professional installers.

Been a long time customer of MMCS, they have serviced my furnace and cleaned my ducts for over a decade. Always friendly, always professional -and always a great value.

My oil furnace tech was awesome, he bled my lines and fixed the issue.

Driver for the company doesn’t understand how two-lane drive-throughout work and proceeded to cut off other vehicles twice -_-

Driver pulling almost ran me off road

They are coming Thursday to fix my oil heater
