We're committed to helping others

Climate change is one of the most significant issues facing humanity. Non-residential buildings utilize approximately 15% of the energy consumed in the United States; and from that, 40% is associated with heating, ventilation, and air-conditioning.

As a leading designer and manufacturer of the most energy-efficient products in the commercial HVAC industry, our innovative designs substantially help our customers reduce their carbon footprint while reducing the cost of building management and maintenance.

We are committed to increasing the production of AAON air, water, and electric-powered units.

From Our CEO

"Sustainability is at the core of our business strategies and corporate citizenship efforts. AAON continues to level up in reducing the energy intensity of our own facilities while also researching and developing new product solutions for the evolving environmental standards. We strive to be a steward of society by leading our people and managing our facilities to benefit the long-term growth of our communities."
