Claim This BusinessCirculating Air Inc has operated from Longmont since 1994, giving the company more than three decades of hands-on experience serving Boulder County and the broader Northern Colorado region. The contractor holds current licensing and carries full insurance coverage, verified through Colorado state regulatory channels. Customer feedback collected across 53 verified reviews yields a 4.8-star average rating, with recent clients highlighting the team's diagnostic precision and transparent pricing. The company maintains standard business hours Monday through Friday from 8:30 AM to 4:30 PM, with on-call availability for documented emergency situations.
This contractor distinguishes itself through a combination of brand partnerships and client-friendly policies rarely seen in the region. They carry Honeywell filtration products and Trane Cleaneffects air cleaning systems, enabling comprehensive indoor air quality solutions for residential properties. Notably, Circulating Air offers a free second opinion policy, if another contractor has diagnosed a major system failure, their technicians will evaluate the findings at no charge. The company also waives all trip fees for service calls and installations, eliminating the upfront costs that deter homeowners from seeking honest assessments. These practices directly address the most common complaints found in negative HVAC reviews industry-wide.
Two customer scenarios illustrate why reviewers consistently recommend Circulating Air. When Alex Greenberg discovered a leaking whole-house humidifier, a technician arrived the same day, completed repairs within an hour, and declined any upsell attempts, an experience the reviewer called increasingly rare. For Imani Gandy, who faced a potential $20,000 replacement quote from another company, owner Bob personally reviewed competing bids and explained why those proposals would have provided 25% less capacity at 25% higher cost. The installation completed in under one day, and follow-up service addressed a refrigerant issue originating from the manufacturer's specifications.
All five detailed reviews award perfect five-star ratings, with four specifically praising technician punctuality and three mentioning the company's willingness to explain repair options without aggressive upselling. The consistent theme across negative feedback in the broader HVAC industry, high diagnostic fees, is directly countered by this contractor's no-trip-charge policy.
