M and M Heating, Cooling, Plumbing and Electrical - Longmont, Colorado

Kelly Musick

M&M is a local, honest company that provides excellent service! Two days before Christmas my heat went out. I called M&M because years ago I had them come do some duct work.
They came, installed with efficiency and highest quality professionalism (They cleaned up after the work was done, and it was almost like they had never been here—except it was warm and smelled fresh.)

It’s amazing to be able to count on excellent service and craftsmanship still today. I highly recommend M&M.

After receiving an outrageous overpriced bid to replace my water heater from another plumbing company, I called M and M to take a look at my water heater problem and give me another bid to replace. It was literally thousands cheaper. Of course we decided to move forward with M & M, this company was exceptionally fast, organized in replacing our water heater and bringing it up to code. Not to mention they took great care in our home making sure it was as clean as they found it. I would highly recommend them!

I cannot say enough good things about M and M and their exceptional team! From start to finish, the service was top-notch. Scheduling was easy, and they were incredibly accommodating to my needs. The workers arrived on time, were professional, and went above and beyond to ensure everything was done to the highest standard.

The technicians were knowledgeable, efficient, and took the time to explain what they were doing in a way that was easy to understand. They handled the installation/repair with precision and care, leaving everything clean and tidy when they finished.

What impressed me most was their dedication to customer satisfaction. They didn’t just do the job—they made sure it was perfect and that I was completely happy with the results. The heating system is now working flawlessly, and I couldn't be more pleased.

If you’re looking for a heating company that combines expertise, professionalism, and outstanding service, look no further than M and M. They truly set the standard for excellence in their field. Highly recommended!

I’ve relied on M and M for the past six years to handle all my electrical projects, and they’ve consistently exceeded my expectations. Their team—especially Chad and Joey—are highly skilled and embody the “measure twice, cut once” philosophy, ensuring every job is done with precision and care. Over the years, they have installed five outdoor security camera floodlights, replaced more than 20 indoor and outdoor light fixtures, swapped out standard switches for over 40 LED dimmers, and upgraded my ceiling fans.

Their clear communication and dedication to getting it right them apart, and I always feel confident in their work. M and M is my go-to choice for electrical needs. I wholeheartedly recommend them to anyone looking for reliable, local, high-quality electrical services.

Daniel was very professional and insightful. His service went beyond what I was expecting. Not only did he fix my issue but also spent time and thought to figure out why it happened and to prevent it in the future. I'll always highly recommend m&m mechanical. Thank you

Joey was awesome!!! He called me before he came to give me a time he would be here, was on time, and very personable and professional. He took the time to explain everything to me that needed to be done and completed the job thoroughly and in a timely manner.
Joey also talked to me about some things that I might consider having done down the road. I appreciated that.
I highly recommend M & M. Great staff from beginning to end.

I recently had M&M Heating & Air Conditioning service my furnace, and I couldn't be more impressed. From start to finish, their team was professional, courteous, and highly knowledgeable. They not only got my furnace running smoothly but also took the time to explain what they were doing at every step of the process.

It’s rare to find a company that combines great service with transparency and a genuine willingness to educate their customers. I felt confident in their expertise and appreciated their thoroughness. I highly recommend M&M Heating & Air Conditioning to anyone in need of HVAC services – they truly go above and beyond!
