Best Heating & Air Conditioning / HVAC In Longmont

“We have had very bad experiences with other HVAC and rooter companies in the past. We are so glad we found M&M for our HVAC and plumbing needs. I really appreciate how patient and informative their tech Cody Gienger is answering all my boiler questions. Also, he seems to know that it's better to maintain a boiler than replace it (we've had companies tell us it was going to die any minute and needed to be replaced or that it would die within a couple of years with no mention of maintenance or how best to extend the life of the boiler). This just adds to our appreciation of the fact that M&M has never tried to make us spend money unnecessarily, and we trust them. On the plumbing side, Abel Aragon saved us from blowing too much money on an expensive job with Elite Rooter, whose high pressure tactics and more expensive services I did not trust or like.“

“It is a great feeling when you need HVAC work done and when the work is completed it not only exceeds expectations but is done at a very fair price. Home Run HVAC and plumbing has done exactly what their name implies; they have hit a 5 Star home run for some very difficult work in my 118 year old home. Highly recommend giving them a call if you are looking for help with heating, cooling or plumbing, you will be very happy if you do.“

“Stone Heating and Air did an excellent job installing a new furnace and AC for my home. They gave us a very fair quote, and were quick to answer all of my questions related to next steps. During the quote process, I never felt like I was being scammed and they were very respectful to our needs. The new furnace and AC are very quiet, and my house is staying COLD during the July heat. Thank you!“

“Groulx Mechanical for the win again! Not only did they do a great job installing my new AC unit, they came back and helped set up my smart thermostat!“

“I don't normally write reviews but Colorado Finest heating and A/C (CFHAC) deserves one. From the very beginning CFHAC has been professional and great to work with. Their initial quote was very reasonable and never changed during installation. Jordon and his crew were very professional and respectful. They showed up when they said they would and not only did a great job with installation but went above and beyond helping me with a previously poorly installed HVAC system (done by another company). I recommend them highly without reservations. Eric Heyer“

“I am super excited to leave a positive review for Circulating Air! Prior to them we were referred to another HVAC company with high Google ratings. Their service guy took one look at our older system and tried to sell us a brand new A/C unit AND a furnace (which we don't need) for 32k+!!! No such cash lying around? No problem--THEY provide easy financing. By contrast, Bryce from Circulating Air helped us with our A/C and reassured us that our system was still good for at least a few more years. Honesty. Integrity. Professional. This company is a bright light!“

“Aaron and his guys are amazing. He helped us in a pinch when selling our house. He did a great job and squeezed us in at the last minute. He is so transparent and we appreciated that so much. I would recommend him and his guys over and over.Services: HVAC system maintenance“

“We had an AC blower fan motor failure and I called another local company to inspect and diagnose. After two weeks and five phone calls, I was told that parts were not ordered and there was no timeline for fixing the unit. I called Blue Valley and they had a HVAC tech out (Jason Baker) within the hour, inspected, conducted diagnostics on the system, and located a replacement blower fan motor within about an hour. I received a call the next day that Jason and new motor were on the way over. My system was up and cooling within 24 hours from my initial call to Blue Valley. They are local, professional, experienced, communicative, and client focused. Jason was highly experienced and walked me through the diagnostics, describing what should be happening during start up etc. and made sure I understood what happened to the unit and how it would be rectified. I ended up learning a lot about my system and heating and cooling in general. It was a super positive experience and I highly recommend Jason and Blue Valley to everyone.“

“Always prompt and thorough! Really appreciate this group. Bob C is truly outstanding in how he approaches the troubleshooting process. Can’t say enough about how much he cares, and wants to make sure everything is working well.“

“Hard working, honest, family owned business. They worked me into the schedule and helped me replace my thermostat. The temps were high so I very much appreciated it. Harvey is a very knowledgeable technician and took the time to help me understand how to operate and make the most of my new thermostat. I highly recommend using them for your HVAC needs!“

“They are responsive and friendly. They guarantee their work, and are very willing to explain things and make complicated systems (to me, anyway) easier to understand.“

“Our furnace was broken, but the utility closet was a weird, tight space that made it hard to replace it. These guys did excellent work, our heat is now working, and they were very nice to my curious cat! Would go with these guys again.Services: Heating system repair“

“I highly recommend this family-owned HVAC business in Longmont! Brien and his crew just replaced our 27-yo gas furnace with a Carrier 95%-efficiency furnace, and we couldn't be happier with their prompt, efficient, and highly-skilled performance. Everybody we dealt with was very personable, and dedicated to doing the very best work for us. Thanks to Lawrence and Zach for doing a great job in a tight crawl-space! A+ business!“

“Took my call but never responded to setup an apt. There was a miscommunication between the answering service and routing the call... They did call back eventually and are correcting the issue.“

“They were all very polite and professional. So far the furnace is working well, and we look forward to getting the A/C finished in the spring.Services: A/C system repair“

“Colorado Green Plumbing is who you want to call for your plumbing needs and repairs. They were recommended to me when I had a leak in my bathroom ceiling. They were prompt, flexible and explained the issue to me, as well explained exactly how the repair was going to go before doing any work.Their staff was incredibly friendly and professional…. A huge thank you specifically to Paul and Nate for the stellar service you provided.“

“Many businesses can be trusted to do the right thing--that is, provided the right thing is also profitable. I'm happy to be able to report that SAC is different: they will do the right thing regardless.

I hired SAC Mechanical for a difficult job, and I paid them well for it. I can report that their crew was highly professional, and that after they left, the issue appeared resolved.

But then, a couple months later, the same sort of problem reoccurred. I don't blame them for this: HVAC are complicated systems, and fixing one part of such a system can induce failures in a different part. But I do find it notable, and praiseworthy, that they came out several more times until the problem was fixed, and that they didn't charge me for any of the subsequent visits.

You may say this is how all businesses ought to operate, and I would agree. But I can also tell you from hard experience that this is not how all businesses operate. Many will give up when the going gets tough--especially if they can no longer charge you. The damage of one potential bad review seems to matter less to them than the cost of sending technicians to do many hours of unpaid work--and the ethics of the situation seem to matter not at all.

I expect that agreeing to fix my HVAC may not have ended up being a good business decision for SAC in the short term. For all I paid them for the first call, at the end of the day I probably cost them far more. And yet they still did the right thing.

Now, I leave this review in the hope that in the very long run, it will also have been the profitable thing too. That is to say, I hope my review will persuade you (yes, you reading this) to choose SAC. They have proven to me that they will keep their word. And when it comes to HVAC, believe me when I say this: you want to work with a company that will keep its word.“

“We’ve been using Service Experts for over a decade and they have always been great to work with. Jordan was at our house for our check up today and was great to work with!“

“From the beginning to the end the experience with TNT was excellent. Craig did an excellent job estimating the job, providing a very competitive quote, and answering all my questions. The installers Adam and Carlos also did an outstanding job in the installation process. They went the extra mile to make sure everything was installed and functioning perfectly. They were very gracious in answering my questions and teaching me the best maintenance practices. They were on time, courteous, and pleasant to work with. I highly recommend this company and give them 5 stars. Doug“
