The Beginning

The history of AAON extends back to 1988 when our founder Norm Asbjornson decided to create a business that designs and produces highly configurable HVAC equipment that excelled in performance relative to the market.

Cutting-edge innovation and engineering were the primary focus since day one. This foundation supported the company’s growth in its early days and is just as important today.  

Over the last 35 years, we have grown from a modest start-up to a publicly-traded industry leader with more than 3,000 employees and facilities across the United States.

With nearly 2 million square feet and the world's most capable HVAC testing laboratory, our engineers are empowered to ask "what if" and advance what's possible. 

From Niche to Mainstream

Secular trends related to decarbonization and indoor air quality are leading to a shift in demand from standard equipment to more capable, highly sophisticated equipment that is more energy efficient while providing cleaner air quality.

As a result, more customers are asking for the "sustainable innovation" that AAON has been providing since day one.

Although sustainable innovation will always come at a premium, our years of experience creating the most efficient automated production operations enables us to deliver the highest quality equipment at a very attractive price.
