HVAC reviews in Longmont, Colorado

We've used these guys for years. They do excellent work and are the kindest and genuine people you will meet.

The nicest, most honest and trustworthy people you could hope to meet. Very skilled and knowledgeable. Highly recommend.

As usual the tech was on time, personable and let me know the status of my furnace and AC unit.

Bob was super efficient and awesome. The lady I spoke with on the phone was extremely nice and down-to-earth as well. Fantastic experience.

Bob is honest and fair. I love that it is a family owned business who cares.

Excellent, friendly service by a local, family-owned company. Highly recommended!

Lavone is the kindest and most efficient person and we will definitely always go back to Circulating Air. What a wonderful company with amazing people!

Bob is the most honest contractor I know, and I know a lot of contractors. His prices are fair and there is a reason he has all these 5 star reviews.

Top notch professionalism and dedication to customer satisfaction. Will absolutely use them again in the future, and recommend them wholeheartedly to anyone looking for HVAC work.

Got my whole home HVAC system replaced by Bob with no hassle, professionally, and on time; all for thousands less than the pushy competition quoted me. I was very happy with the entire process.

Bob and Tony are always on time and have done a great job for my family and I for years. Highly recommended!

Wow! Above and beyond customer service! I was quoted $3500 to replace a furnace by 2 other companies and Bob was able to replace a part for almost nothing and it’s working like a charm. I’ll never use anyone else.

Had a very well-established HVAC company come out -- we've used them for a while. They kept selling us new stuff ... new furnace (understandable, it was old), new water heater (kind of suspicious, because it wasn't that old -- but ok), then saying we needed a new AC (a 7 year old unit). That's when I was like -- holy moly -- we've been getting played. Found Circulating Air on Nextdoor and they were like "nothing is wrong with this unit, call us in 2 years -- or sooner if something is an issue." TONY you are awesome. I will be telling everyone about you. Thank you for the honesty.

In behalf of tamara, a 5 star rating. Yvonne wonderful and so helpful. Great team.

I love this company!! They are responsive when we need help.. When our tenants need help with heat or A/C they make sure to take care of each and everyone!
I recommend this company!!

I was extremely impressed with the professionalism and integrity of Bob

Bob arrived when he said he would and after doing checks on the A/C system, he determined that the Thermostat was not working properly on the cooling side as I suspected. He was about to start swapping out the unit until I told him that the previous tenant/owner had a Google Nest installed and must have replaced it with the current Honeywell unit before he vacated.

Bob paused for a second and started thinking. He then said that that maybe the owner forgot a critical wire connection while installing the Honeywell thermostat due to differences in the wiring between the two units. Bob grabbed a small jumper wire and added it, then the cooling system kicked on and has been working great since then.

He saved the property owner the cost of a new thermostat in the process. That kind of honesty goes a long way.

I called them because I had no heat. Service man came within 30 minutes fixed issues and I was back in business. Couldn't be more pleased with the service, was the second time I've used them and wouldn't hesitate to use them again. Thank you Circulating Air!!

I have been using Bob and his team for 18 years. Circulating Air is honest and reliable whether you are installing a new heat and air unit or having a service. They are prompt and respectful if your home. 5 stars!

Thank you for taking such good care of our house! Not only is the service great, it’s wonderful to have the information to understand what is happening and what needs to happen. Thanks!

Really great service. Extremely good communication with the office. Bob, and Tony especially, knew exactly what we needed to match our 20 year old dual system. They got it right, then they came back free of charge and made it even better. Would highly recommend. Thanks Circulating Air! Very happy customer.

When the company couldn't come to fix our heater because they were booked solid for the entire week (speaks well of the company), they referred a trusted competitor because they were concerned when we told them there was a small child in the home! The weather then was still warm enough, so we waited instead of using the competitor. A couple days later, the company had an open spot and Tony fixed the heater. A few days after, the heater quit working again. Bob came out, fixed the problem at NO additional charge. WOW!!
Honest, fair, wonderful people.
