M and M Heating & Cooling, Plumbing & Electrical

Sara F.

What a Lifesaver! After driving all day we arrived home
to a freezing house without a hint of heat. Early the next morning after checking possibilities online we called
M and M to schedule an appointment. Within an hour Mark arrived, checked out our VERY old furnace and offered 3 different pricing options for replacement. Later that day his crew arrived to begin work. This was not an easy install and the crew stayed well into the evening to get the job completed. All of the workers were friendly, prompt and professional. The clean-up was great and
now I have much needed heat in my house!
I am pleased beyond belief!
I whole heartedly recommend M and M. Fair pricing, stellar service and locally owned. . . (Something I always try to support.) Were it possible to award a 6 star rating I certainly would!

I am writing this review because I think M&M deserve to be bumped up to the next star-level on their Yelp ratings. I have only good things to say about my experience with this company. Cody, the technician who diagnosed my failed heat exchanger in my old Lennox, did an excellent job for me. I purchased a new Carrier system because not only was the the old Lennox furnace toast, but the interior evaporator coil for the Trane A/C had also failed. Both units were good in their day, but after 13 years of service, they needed to be replaced.

The price for the system was the best among the 3 quotes I received from different brands and HVAC companies, and Isi and Jarme, the installers, did an excellent job. I even took my carpenter's level to see if the new condensing coil was level on the new slap they put outside, and yes, the bubble read almost perfectly level. I have complete confidence in the system and this company to take care of any future needs I may have.

WARNING: M&M cannot be trusted. Here are the facts:
My furnace lost power. Technician Mark was paid to diagnose the problem ($90), which he NEVER did. Instead he changed the thermostat, replacing a working one with a new one. This didn't (and couldn't have) solve the problem as the thermostat draws its' power from the furnace. He charged me $171 for a unit that sells for $30 at Home Depot. Plus $90 installation. The new thermostat has the unique feature of the M&M company name and address printed on the front of the thermostat. Really cool to add the M&M name to the wall in my dining room. This says everything there is to know about this self-interested company. Disgraceful!!!
Next, technician Mark spent 45 minutes in his van preparing for me a four-page proposal of furnace replacement options from $12,000 to $24,500. He never diagnosed my furnace problem. He was there from the start to try and sell me an overly high-priced new furnace. M&M furnace pricing is price gouging, double the prices of some competitors, contrary to the M&M website.
WARNING: M&M is a dishonest organization. Just read between the lines at their website. They are a self-interested ""family"" company that lives the lie that their approach ""allows us to offer the best products available at a much lower cost to you during these tough times."" Simply, a lie. The website continues by insulting their competitors: ""We strive to keep our business simple and effective. The large volume businesses (competitors) require high overhead costs which include daily advertising, higher insurance costs and more company vehicles just to name a few. In the end these costs are passed onto the consumer."" Simply put, this is a very poorly written and deceitful attempt at a marketing message.
Upon request they did refund my money and told me to keep the thermostat. They thought they were being thoughtful & generous. More likely, they were caught in their game and were worried about being reviewed negatively. Instead, these are the indisputable facts, verified by the work order & invoice.

Asked this company to give me a quote for some simple work. They took apart my AC unit, pointed to something unrelated, said I need to replace the entire unit, and gave me quotes for replacing my entire HVAC system. Hired someone else who just came out and did the work. Don't let these guys into your home.

M and M Heating & Air Conditioning, Plumbing & Electrical is based in Longmont, Co but had no problem servicing my dishwasher in Lyons, CO. They were also accommodating to my two napping toddler's schedule and made sure they came earlier in the day. You know it's a great run family business when they acknowledge the importance of naps! As a new homeowner, I was given a lot of information about my dishwasher I didn't know in addition to the maintenance that needed to be done. I will definitely make M and M Heating & Air Conditioning, Plumbing & Electrical my first call when issues arise in the future. Hopefully it will be awhile since they provide the best service in Longmont, CO.

These guys are great. I've been doing business with them for almost 15 years. From the AC they installed back when they were still a small shop on Main St. to the new hot water heater and furnace/AC replacements in the past year. They have grown a lot and offer more of a one-stop shopping experience now that they do HVAC, plumbing, and electrical work.

It took Aleks, Issa, and Aaron ~6 hours to rip out the old AC and furnace and replace with a more efficient and quieter Carrier Infinity system. Install looks flawless and everything has been working great. They explained how all the bits worked and I am a satisfied customer.

Eric Meiers and his company installed our AC 20 years ago when he was first getting started. I am happy that his company has grown and that he still hires only the best employees.

Aleks and his team installed our Carrier AC & Furnace units in under 6 hours. And he took the time to go over the entire installation and explain everything. It all looks and works great!!

Now that Eric's company has expanded to plumbing and electrical, we will be sure to call his team for all of our house maintenance.

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.
