A&O Heating & Air Conditioning

A&O Heating & Air Conditioning operates from Greeley, Colorado and extends professional HVAC services across Northern Colorado, including Fort Collins, Loveland, Windsor, Longmont, Boulder, and Fort Morgan. The company specializes in both heating and cooling system installation, replacement, repair, and maintenance, with particular emphasis on indoor air quality solutions. Homeowners and light commercial property managers throughout these communities turn to A&O when systems fail unexpectedly or when planning new construction projects that require integrated HVAC design.

The contractor distinguishes itself through active participation in multiple utility rebate programs, serving as an approved trade partner with both Atmos Energy and Xcel Energy in Colorado's HEAR program. This authorization opens access to state-supported incentives for furnace and heat pump upgrades, including Colorado tax credits and efficiency works rebates. Beyond utility partnerships, A&O offers comprehensive indoor air quality services including UV lights, air purifiers, ERV/HRV systems, and humidifiers, solutions particularly valuable in Colorado's dry climate where proper humidity control directly impacts home comfort and energy efficiency.
