About AAON: A Leader in Commercial HVAC Manufacturing

AAON, Inc. has been a driving force in the heating, ventilation, and air conditioning industry since its founding in 1988. Headquartered in Tulsa, Oklahoma, AAON was established through a management buyout of the John Zink Company's HVAC division, with Norman H. Asbjornson leading the charge to build a company focused on semi-customized, energy-efficient HVAC solutions. Today, the publicly traded company employs approximately 4,000 people and operates manufacturing facilities in Oklahoma, Texas, Missouri, and Oregon.

What sets AAON apart is its commitment to highly configurable equipment. Rather than offering purely off-the-shelf units or fully bespoke systems, AAON targets the space in between — delivering tailored solutions that meet the precise demands of commercial and industrial customers without the cost of full custom manufacturing. Their equipment serves a diverse range of applications, from schools and hospitals to data centers and retail spaces.

AAON's Approach to Controls and Integration

AAON's philosophy extends beyond the equipment itself. Through its AAON Controls division (bolstered by the 2018 acquisition of WattMaster Controls), the company designs and validates the sensors, controllers, and software that work seamlessly with its mechanical equipment. This end-to-end integration means that every component — from the HVAC sensors and probes to the furnace and A/C control boards — is engineered to communicate reliably within AAON systems. The result is a level of system cohesion that reduces diagnostic uncertainty and supports long-term operational efficiency.

Replacement Parts Built for AAON Systems

When an AAON commercial rooftop unit, air handler, or heat pump needs service, using genuine AAON replacement components is the most reliable path to restoring performance. HVAC blower motors and HVAC replacement motors are among the most commonly serviced components in AAON units — keeping airflow consistent and protecting downstream components from the strain of a failing motor. Likewise, gas-fired AAON heating equipment relies on properly functioning gas valves and controls to stage combustion safely and efficiently.

Because AAON has refined its control platforms and equipment designs across multiple generations, matching the right part to the right unit matters. AAON's broad catalog of OEM replacement components — covering motors, sensors, control boards, valves, and more — supports technicians and facilities managers in maintaining peak system performance across AAON's wide range of commercial HVAC models.
