Circulating Air Inc

Circulating Air Inc serves Longmont and surrounding Northern Colorado communities as a licensed residential heating and cooling contractor. The company holds a 4.8-star rating across 55 verified customer reviews, placing it among the most highly recommended HVAC providers in the Boulder County area. Founded in 1994, the business has accumulated more than three decades of hands-on experience installing, maintaining, and repairing furnace systems, central air conditioning, heat pumps, and garage heaters for homeowners throughout the region. Their service roster includes air filtration units, humidifiers, and electronic air cleaners designed to address indoor air quality concerns common to Colorado's variable climate.

This contractor distinguishes itself through two customer-friendly policies rarely found in the industry: a zero trip charge for service calls and free second opinions on repairs or installations another contractor has recommended. They carry Honeywell filtration products and Trane Cleaneffects air cleaning systems, offering homeowners access to major brand equipment with known reliability records. All technicians maintain proper licensing and insurance coverage, and the company provides written assessments before any work begins, allowing customers to make informed decisions without pressure.

Customer reviews highlight specific technicians who delivered exceptional service. A reviewer described Tony diagnosing and resolving two hidden HVAC issues in a single hour, while another detailed Bob taking time to explain why competing bids were overpriced. One homeowner recounted the team arriving same-day to repair a leaking humidifier, completing the work within an hour without attempting unnecessary upsells. Another noted the crew returned promptly when a new AC unit failed to cool properly, identifying a manufacturer refrigerant error that previous estimates had missed.
