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“

“Colorado Green Plumbing is amazing. Not only did the technician walk me through what the issue was, he did not choose the most expensive method to fix the issue, he started small and the fix worked. This is like the old days were the folks showed up on time, you could trust them and they wanted your business for life, not just for a short term profit!“

“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.“

“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!“

“Work accomplished within apptox 1/2 hr !
Well done. Lovely people . Will recommend
To others in my neighborhood. Reasonally priced as 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!“

“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.“

“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!“

“Our heater stopped working so we contacted SAC Mechanical and Stan was able to come to our house, diagnose the issue and get the heater running again very quickly. He was prompt, professional, knowledgeable, friendly and courteous--5 stars!“

“Corey and Vertical Heating&Cooling are simply unbelievable! One of our two water heaters was flooding into the crawl space along with flooding from a water line. The two were not related but created a giant mess. Corey responded right away. Reorganized his schedule for our emergency! Corey not only replaced the ruined duct, but called a water restoration company for us. Repiped and Installed a tankless heater, and did a maintenance check on our HVAC. When nobody would respond to our emergency, they were here within two hours. Their cost was very fair and their professionalism was off the charts! I highly recommend Vertical Heating and Cooling!“

“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“
