I called at least 4 plumbing firms to get a leak in a hot water line by our hot water tank repaired. All were out at least a week before they could even come by for an estimate, and one quoted $1100 without even diagnosing the issue. Then called Greg at MM and he took immediate interest and FaceTimed me to further diagnose the issue. He gave me an approximate estimate and said he would try to get someone out that afternoon. Josh then did come to do the repair the same day (!) and suffice to say it was so reasonable I was pleasantly surprised, something I’ve never said before about a plumbing repair. I will be calling MM again for any plumbing or electrical needs.

M&M does pretty much all our HVAC, plumbing, and electrical work. They’ve installed a new furnace, a new water heater, water pressure booster pump and other plumbing, and most recently ran new wiring for overhead lighting in two rooms. We’ve always had great experiences and this time was no exception. Jacob and Jacob were efficient and professional and very pleasant to work with. Highly recommend M&M for all systems work.

Worked with them through Costco for furnace replacement and AC install. Estimate and installation process was very clear. Some things had to be modified at install time, but they were upfront and informative about why. System is working great and Sam and Antonio were awesome.

Installation is smooth and Luis & Mario, the technician are very professional on their job. Justin, the electrical technician, is also very nice. They came on time, finish the job quickly and clean up all the area after the service. He also went through their work with me after they finish the work. All work looks very solid. Glad I finally have the AC at my house.

I connected with MM Comfort Systems through Costco. My installers Luis and Mario were excellent and very knowledgeable. Everything was done on time and very professionally. They let me stick with them through all the work and it was very enlightening. While observing all the work being done, I realized what a great value I was getting for my dollar. The equipment is of high quality and fully functioning right out of the boxes!

MMComfort Systems was the third bid that we received. It took the longest to schedule, but it was definitely worth it to get a top of the line HVAC system professionally installed at a reasonable price. Ruslan and Dallas did an outstanding job installing the furnace and AC! Our dog even liked them! I especially appreciated the time Rus took to answer my questions and walk me through the new system. I also appreciated that MM Comfort was able to schedule the installation, the electricians and the duct cleaning all in 3 days. My wife and I are very happy!

Zach & Jeremy came in to replace a furnace and install a new heat pump. We went with the Carrier Infinity system and they did a really professional job with the installation. They were prompt, on time and courteous. They did a good job and everything passed inspection without any issues. Plan on using MM Comfort Systems for all our HVAC repairs and maintenance.
The mini split system we purchased works great! I have lived in this house for over 40 years and expected the system to be good, but this is fantasic! We purchased through Costco and got a great price. The installers Mikel and Ina were efficient and friendly. They left the areas where they worked completely cleaned up! I highly recommend MM Comfort Systems!!

This is the second time I've hired MM Comfort Systems, first time was through costco, 2nd time I reached out directly. They replaced an old furnace and installed a new AC. They were professional and on time. When they got here they looked through various parts of the ceiling and wall to determine a least intrusive way to route the AC coolant lines. Their patchwork was also well done aesthetically. They installed the components and AC was up and running within 8 hours. Drew and Jason did a great job with the unit, I have already recommended MM Comfort Systems to some neighbors.

Chris was so helpful from the very start! He arrived right on time, diagnosed the problem, walked us through our options, and never once did we feel like we were being upsold. He replaced our water heater that day, and we are thrilled with our new appliance! Chris was kind and very easy to work with. thank you! MM Comfort Systems!

MM Comfort Systems (Home Comfort Alliance) came out to install a new furnace and A/C unit. From start to finish, we were kept informed about everything. Zach & Devin showed up on time and informed us about everything they were doing and how things worked. They worked diligently, and were knowledgable about the process. They answered all of our questions. I would recommend this company for service as well as install.
