Recommended Customer Reviews
Richard M.They were professional, quick, and their work was excellent.
I had a faucet fail unexpectedly and they were able to come out within 36 hours, which I found met my needs. They were careful to ask whether I considered my situation an emergency and, since I did not, that timeline worked for me.
We came home from vacation on a toasty Sunday afternoon to find that our AC was kaput. After calling several HVAC companies whose Yelp listings said they were open weekends but weren't I left a message with M and M's answering service, got a call back within a few minutes from Lalo, who was able to fit us in within a couple of hours. He was professional and friendly, explained what was going on, fixed the problem quickly, and took a few minutes to check out the coolant pressure on our aging AC and talk to me about replacement options (heat pumps are it). Great experience and will be calling these guys first from now on.
had new central humidifier installed today. installers arrived on time, inspected the install location and said about 90 minutes for job.
very professional and courteous.
highly recommend M&M HVAC
Julie S.Derrik is my HVAC hero! My furnace has had issues since February of this year, and two other companies failed to find the actual problem (after charging hundreds of dollars for other ""fixes""). Derrik was able to determine exactly where there was a blockage in the condensation trap. Not only did he find it, he cut the trap in the perfect spot so I could see the blockage (excessive glue that had dried up from when it was originally installed). He also educated me on everything he was doing and ensured he had all the right parts before he started cutting. He was there at the right time just before it starts getting even more cold and I cannot be more grateful.
Thank you, Derrik!!
Trey Roberts did a great Job working on several odd job electrical projects for us! Fast, efficient and respectful of ensuring the job was done right. Thanks!
Excellent customer service and timely response time. Lalo is extremely knowledgeable. Highly recommend them for all your HVAC needs.
I was working out of town when our AC went out; called them around 3:00 and they showed up before 5. Replaced a capacitor and had the unit running in about an hour. I was a little taken aback by the price of the part and called to question. It was explained that labor was a part of the ""cost"" of the part and I appreciated the explanation. Will use them again for our needs.
Peter C.These guys should be 5 stars all the way!!!

My furnace stopped working this past Friday night when it was in the teens overnight. Lalo came out on a Saturday, answered all my questions and had the problem fixed in no time. He was very professional and extremely helpful.
Amanda L.Our AC broke on a 90 degree day in Colorado during wildfire season negatively affecting the air quality. Not a great time to lose our AC. I called multiple places but only M and M could get someone out right away! Brien came and was super helpful. He amazingly repaired a 24-year old unit when we said we weren't ready to pull the trigger on a new unit. He gave us our options, fixed it and it wasn't a fortune! They were on time, reasonably priced and really easy to work with. We do plan to replace our unit in the off season and will likely go with M and M after their great customer service, skill and diagnostic abilities.
