AAON is a manufacturer of semi-custom commercial HVAC equipment, including packaged rooftop units, air handling units, split systems, heat pumps, and condensing units. Founded in 1988 and headquartered in Tulsa, Oklahoma, AAON engineers, manufactures, and markets heating and ventilation equipment for commercial and industrial buildings across the United States. The company operates manufacturing facilities in Tulsa; Memphis, Tennessee; Redmond, Oregon; Kansas City, Missouri; and Longview, Texas. AAON's commercial rooftop units are available in capacities from 2 to 240 tons, covering light commercial retail spaces through large industrial buildings. Trade contractors and mechanical engineers specify AAON equipment for commercial new construction and retrofit projects where semi-custom configuration and factory-direct engineering support are priorities.
Product Lines
RQ Series Rooftop Units
The RQ Series is AAON's standard-efficiency packaged rooftop unit line for light and medium commercial applications, including retail, office, and light industrial facilities. RQ Series units are available in a range of capacities and can be configured with various heating, cooling, and ventilation options to match the building's mechanical requirements.
RN Series High-Efficiency Rooftop Units
The RN Series is AAON's high-efficiency packaged rooftop unit platform, designed for commercial applications where energy performance is a primary specification driver. RN Series units support advanced controls integration and variable-speed operation, targeting higher-efficiency projects with expanded options for energy recovery and advanced refrigerant management.
SA and SB Series Air Handling Units
The SA and SB Series are AAON's custom air handling unit platforms for commercial and industrial building ventilation. SA and SB Series units are factory-configured to match specific CFM, static pressure, heating, cooling, and filtration requirements for large commercial facilities.
H3 Series Water-Source Heat Pumps
The H3 Series is AAON's water-source heat pump line for commercial buildings using hydronic loop systems, including office buildings, schools, and multi-unit commercial properties. H3 Series units connect to a central water loop and can provide both heating and cooling from a single unit.
V3 Series Variable Refrigerant Flow Systems
The V3 Series is AAON's variable refrigerant flow system platform for commercial applications requiring zoned, multi-unit heating and cooling control. V3 Series systems allow individual zone management within a shared refrigerant circuit, making them appropriate for office buildings, hotels, and commercial spaces with diverse occupancy patterns.
Why Contractors Specify AAON
AAON has been engineering and manufacturing commercial HVAC equipment in the United States since 1988, with multiple domestic manufacturing facilities across Oklahoma, Tennessee, Oregon, Missouri, and Texas. The semi-custom configuration model allows mechanical engineers and commercial contractors to specify rooftop units and air handlers with factory-set options that match the building's precise load, airflow, and controls requirements. AAON markets its equipment through a manufacturer's representative and contractor channel, which means commercial mechanical contractors work directly with trained AAON representatives for project support and engineering documentation. The company's commercial rooftop unit capacity range — from 2 to 240 tons — covers light commercial through large industrial buildings within a single product family.
