“On an extremely cold morning in late January, we woke up to a broken furnace. I called M and M and Derrik A arrived within hours to assess the situation. He was incredibly competent and kind. Two days later, Derrik A returned to our home with Cody G and John S to replace our ancient furnace with a beautiful shiny new one. These three men were courteous, conscientious, and professional, as well as incredibly knowledgeable. I am grateful that they went above and beyond to help us. We will be recommending M and M Heating, Cooling, Plumbing and Electrical to friends, family, and anyone else who will listen.

I am grateful to M and M once again for doing a stellar job! I am impressed with all of the professional, kind and knowledgeable men who installed our mini splitter. AJ B, Gabriel R, Gabe B, Jonathan A, Aleks A, and I believe Matthew, were wonderful!”

“Mike at Longmont Water Heaters is the real deal. Fast, detailed, affordable, and friendly. We got estimates from other companies that just made me laugh. Mike was clear with what was needed from the beginning and stuck with that all the way through without unnecessary labor charges or equipment add-ons. Recommend without hesitation.”
