Victor came to our home and was professional, courteous, knowledgeable, and efficient. He correctly diagnosed a leaking toilet problem, fixed a leaking faucet, and sealed a sewer vent pipe that was preventing us from final carpeting our basement remodel. Can't say enough good things about Victor, and we will not hesitate to call on M & M for anything in the future.

M and M, you guys do good service when things are needed, you guys get to calls in a hurry. But the last few times your installers came out here they left there trash laying around, my house stunk in a bad odor of Marijuana for hours on top of hours, there cigarette butts were left if my yard. This is not the M and M ""business"" that first came out to my house

I've been working with M&M for over 10 years now at multiple locations. They never disappoint, are always timely and provide professional quality work at a fair price. They recently replaced my parents furnace last minute while they were snow-birding in Texas. Because temperatures were freezing at night M&M worked with no one onsite and got them back up and running before any pipes could freeze. Great job Cody! Would highly recommend any services they provide.

M and M Heating & Cooling, Plumbing & Electrical was so great to work with. Every time I called they got my an appointment right away. Brian had come in, diagnosed the problem with our kitchen faucet and gave us the options on how to get it fixed/replaced. After that, they were willing to work with our schedule to come out and replace our faucet -- which Brian and Victor did very quickly! They were a pleasure to work with, and very affordable. I will definitely be using M and M again!

First, I waited until AC unit was working again to write review (not fixed by MandM). My experience: I contact MandM with my larger AC unit that seemed to not work as high heat of summer happened. I also requested that they look at freon levels in my second unit. The first larger unit gets unhappy every summer when temperatures get above 95. In retrospect, I think I got an inexperienced repair person who didn't call for help when he didn't know what was wrong with my AC unit and instead gave me a list of all the parts inside the first unit that might need to be replaced to get it working, as part of his tactic for pushing a new unit sale. Justin admitted that he had no specific idea of which part was not working in it and suggested that I start considering a new unit. He also charged me for looking at my second unit which he said he was too afraid to service because the number readings didn't make sense and he didn't want to mess it up. It was kind of him to not mess it up but I should not have been charged for second unit when it was not really serviced. I wrote online to company to complain about Justin's service and never heard back via email or phone message. Might be best to request more seasoned repairman for older units.
Update: Thanks for the response, Eric. M an M service both units prior in 2012. They serviced and repaired the second/older unit and it's worked like a champ ever since so there was absolutely nothing wrong with it but I wanted to have it check and service since it had been so long. Additionally, M and M did a repair service call on first unit in 2014 and found loose wire. Justin had no idea how second/older unit was operating since ""the numbers"" didn't make sense to him and he didn't recommend servicing it due to that. He also wanted to order a laundry list of parts for first unit (think 2005 model) because he didn't know why it wasn't working but recommending replacing the entire unit. The second opinion company immediately knew it was the capacitor. Many units are capable of lasting more than the industry standard with proper care, especially in Colorado where some only are used 4-5 months of the year. I stand by my opinion about Justin.

I got the pleasure of meeting Brian, he installed a water heater very fast and efficiently. He's a friendly personable guy and he loved my dog. Everyone at M&M were very pleasant. I will recommend these guys to everyone! They beat every price in town.

We needed to replace our air conditioner and furnace. We have worked with M&M before, so they were our first call. Lalo and Aleks did a great job, They were friendly and professional. They worked efficiently and left without a trace of a mess. The new air conditioner is so quiet that the only way you know it's running is by the whisper of cool air coming out of the vents. We couldn't be happier!

Very happy with their service. Technician (Brien) was on time, courteous, and professional. He checked every detail and was able to resolve the problem with my central air conditioner quickly and at a reasonable price. Would recommend to friends and family.

The very definition of UN PROFESSIONAL. these turds came to one of my stores to check out one of the roof top A/C units. The guy said he'd price the needed repair parts and send me the estimate. That was a week ago and he completely flaked out on me. He never even bothered to call..... The office says this jerk is out of town for a week and he's un reachable. What kind of losers send someone out to service a customer of he's not going to be around to do the repairs? What kind of company is this that they don't give a crap that their employees are going around ruining their reputation? We needed a new contractor to service our 10 stores in the greater Denver metro area. It sure as hell won't be these losers.
