HVAC reviews in Longmont, Colorado

I'm unable to say enough good things about Bob and Circulating Air. Honest, professional, and old fashion "customer first" type of service. There are very few companies like this one left. Thank you for always taking such good care of us!

Highly recommend these guys for inspection/service, especially if you have an older unit/system. I saw how they handled a neighbors A/C unit and overheard Bob dropping some knowledge on how they could FIX, rather than go straight to replacing. They were SUPER happy. So, I had them come out to service my roof top unit and my furnace stack. Even though it's an older set up, they said it was solid, freon was good, and it should last. They also saved my sanity by making our neighbors unit (which is also on my roof) 98% quieter with some rubber feet. Talk about a relief! Anyways, Bob and his guys are super professional, knowledgeable, and friendly. Lavonne (sp?) in the office was also great to deal with.

We have used CA three times in the past for various AC/heating related things, and I could not be more pleased with the service. Very professional, pleasant techs (Bob and his son), and they provided perfect service at very reasonable prices. I have recommended this company to multiple people and will continue to do so. They're simply great.

So pleased with my experience. No upsell, Toni explained what he was doing and helped me understand what I needed to know. Extremely honest and my AC works again I Highly recommend them. This is a family owned business out of Longmont. Thank you.

We have used Circulating Air for two of our homes and both times we were extremely happy with the service, friendliness and fair pricing. In a world where you feel everyone is trying to squeeze an extra dime out of you- it’s so nice to find a reliable and trustworthy company to help with any and all heating and cooling needs. Don’t bother doing any more research- this is the company you want. Bob was our technician both times- very nice and knowledgeable. Lucky to have found them!

I had been searching for a good HVAC person for a long time and I’m so glad I found Bob at circulating air. He is honest, does high quality work, charges very fair prices, and has absolutely top notch customer service. For example, I recently had a gas smell after he installed a new furnace. He returned to investigate immediately and discovered it was due to a faulty water heater installation done by a different contract. Despite it not being his responsibility, he fixed the water heating and did not charge me a dime for the work or for the visit. This type of above and beyond service is the reason I recommend circulating air to everyone I know.

Wonderfully professional makes me feel comfort that when I need to replace my furnace I can go to Bob and his team with no worries. Best value in town. Trustworthy. A jewel 💎 in the heating business. Not to mention Yvonne who is awesome 👏 and so helpful. I will recommend this company forever. Thanks circulating air for all you for the community.

Have been a customer of Circulating Air since 2001. They are the BESTEST!!!!!!! Friendly, Genuine, Honest, Show Up, Dependable, Knowledgable and will never try to sell you something you do not need. -Once I had surgery (in another state)-came home late at night to no furnace -temp were in the teens. I stayed up all night throwing towels in the dryer to wrap myself in to keep warm-- Bob came 6am in the morning to fix the furnace for me. I will ALWAYS and only call Circulating Air for all my HVAC I refer them to all my Friends and Clients!!!

Excellent experience both with the selection of equipment and the installatio of two complete HVAC systems.

I was so impressed with the service offered by Circulating Air, Inc. The communication was top notch as well as customer service and service and general. They were timely with scheduling an appointment and provided detailed information regarding the service offered. I would recommend them to anyone looking for and HVAC technician in the area.

We love Circulating Air. They have serviced our HVAC system for several years. The techs are friendly, down to earth, and knowledgeable. They charge fair prices. This is a family-owned company committed to customer service and it shows.

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!

Extremely responsive and professional. We had a humidification system installed and they were a great price and also helped diagnose/resolve another unknown problem in our HVAC system while they were working on it.

Will absolutely use again in the future and highly highly recommend.

We had Circulating Air install AC for us at the beginning of September. They were great to work with and didn’t inflate the pricing like other companies that sent us bids. They were in and out within a day. They were super responsive, easy to work with, and reliable. I would definitely recommend them.

Glad I found these guys. They were quick and professional, solved the problem, no upselling. They'll be who I call again in the future.

If you're sweating to death in your house because your AC died and you've been told you have to get everything replaced to the tune of about twenty grand, but you don't know a single thing about HVAC installs and are concerned about some nefarious company screwing you over—

Relax. You've found the right place. Bob and his crew are excellent—and they're honest. Liz in reception is very nice. I got estimates from multiple places and even though I hadn't yet signed a contract with Circulating Air, Bob took the time to explain to me why the other bids (from Cooper and DNI) were actually terrible. It turned out they were offering me about 25% less for 25% more.

The install took less than a day. When I had a problem with the AC keeping the house cool, they promptly came out and fixed it (turns out it was a manufacturer instruction error about how much refrigerant to add.)

It is stressful when you're about to drop 18K on a big project—particularly if you don't know anything about HVAC and are ripe for being ripped off.

Go with Circulating Air. You won't be sorry. Also, if you're contemplating going with a place that offers financing, don't. Try to get a HELOC or other sort of bank loan. It ends up being cheaper.

Thank you, Circulating Air!

We had Circulating Air install a furnace and a year later an AC. Incredibly competent, responsive, honest and more competitive than Boulder HVAC contractors. We had an issue a bit out of their warranty that was not their fault and they quickly resolved the issue. We highly recommend.

Had a great experience with Circulating Air in Longmont. My HVAC tech, Tony, was professional, thorough, and easy to work with. In just an hour of labor, he diagnosed and fixed two issues I didn’t even know I had. Excellent customer service and truly excellent value—highly recommend.

I called due to a leaking whole house humidifier and they sent a technician the same day. There was no upsell, and the work quality was phenomenal. They reviewed the issue and fixed it within an hour and also checked the thermostat and my AC unit. This type of service is increasingly rare and I wholeheartedly recommend them.

The Welzig team evaluated and provided solutions for cooling issues in our home. We were able to quickly get an appointment for an initial evaluation, and the technician, Bob, arrived timely and listened to our concerns and offered options. We had a follow-up appointment with Casey Welzig to discuss installing a new system. He was very thorough in his explanations and transparent about potential limitations. We opted for a new system, which the team was able to install 2 days after we decided to purchase. James, Anthony, and the team did a great job on the installation. They went above and beyond and stayed late to finish so that we would not be without cooling overnight. Our new system has been performing well - able to keep the house cool in 90+ degree weather that our prior system could not handle. All-in-all, a great experience with the Welzig team.

Welzig has been fantastic. We have replaced air con, furnace, hot water heaters...always professional and timely.
