Circulating Air Inc
Circulating Air Inc is a family owned and operated HVAC company in Longmont that has served the Boulder County area since 1994. Owner and founder Bob Russell started in the heating and air conditioning trade in 1977, ran his own company in Southern California from 1982, and was one of the youngest state licensed heating contractors in California before moving his family to Longmont and opening Circulating Air. Bob and his son Tony run the business today. The company handles residential heating and cooling from installation through repair and seasonal maintenance, including Trane central air conditioners, high efficiency Trane furnaces and heat pumps, thermostats and smart thermostat upgrades, Flow Thru whole home humidifiers, and Modine Hot Dawg heaters for garages and workspaces. Indoor air quality work covers Honeywell filtration and Trane CleanEffects air cleaners, which capture particles as small as 0.1 microns and help with wildfire smoke and seasonal pollen. Technicians are fully licensed, insured and NATE certified, and they work on all makes and models. Pricing is upfront and competitive with no hidden fees, there is no trip charge for coming out to a job, and the company offers a free second opinion for homeowners told they have a heating, cooling or ventilation problem.
