AAON, Inc. AAON

Company Overview

AAON, Inc. is a U.S.-based manufacturer of heating, ventilation, and air conditioning (HVAC) equipment focused primarily on commercial and industrial markets. The company designs and produces semi-custom and custom HVAC systems, rooftop units, chillers, air handling units, packaged outdoor mechanical rooms, energy recovery units, and related controls. AAON operates within the broader HVAC and building efficiency industry, serving sectors such as education, healthcare, data centers, manufacturing, retail, government, and commercial real estate. Its principal revenue drivers are sales of engineered HVAC systems and replacement equipment, with demand influenced by non-residential construction activity, retrofit cycles, energy-efficiency regulations, and indoor air quality requirements.

AAON was founded in 1988 and is headquartered in Tulsa, Oklahoma. The company evolved from a regional HVAC manufacturer into a specialized producer of premium and highly configurable HVAC solutions emphasizing energy efficiency and customization. AAON has differentiated itself through vertically integrated manufacturing, proprietary engineering capabilities, and a focus on high-performance systems for demanding applications. The acquisition of BASX, Inc. expanded its exposure to mission-critical cooling markets, particularly data centers and cleanroom environments.
