History
Norman H. Asbjornson founded AAON in 1988 with the goal of creating semi-custom HVAC equipment for commercial applications. He purchased the heating and air-conditioning division from John Zink and chose the name AAON to ensure a prominent placement in telephone directories.
The company commenced operations at its Longview, Texas facility in 2000. Significant investments have been made to enlarge this plant, including a $28 million expansion initiated in 2019 and the completion of a 220,000-square-foot building the same year with an additional $40 million spent. In 2023, the Longview Economic Development Corporation approved a second expansion valued at $40 million, expected to be finished by 2024.
Acquisitions
AAON expanded into HVAC coil manufacturing by acquiring Coils Plus in Longview, Texas, in 1991.
In 2018, the company acquired WattMaster Controls (WCI), based in Missouri, and took over its previous facility through leasing arrangements.
The 2021 acquisition of BASX Solutions (BASX), an Oregon-based firm specializing in the design and manufacture of high-end custom commercial HVAC units for data centers, clean rooms, and specialized markets, further broadened AAON’s product offerings.
