Early Life

Norman Harold Asbjornson was born in Winifred, Montana, on December 10, 1935. Growing up during the Great Depression, Asbjornson learned the value of hard work and perseverance from a young age. At the age of 10, he started his entrepreneurial journey by hauling water for chickens in exchange for a Model T. He graduated high school in 1953.

Rise to Success

Over the next 12 years, he held six different jobs in five different cities, honing his management and sales skills. In 1988, after 28 years in the industry, Asbjornson founded AAON (a play on the fact that it would be listed first in the phone book). He led a management takeover of John Zink's HVAC division and took the company public in 1991. Under his leadership, AAON secured significant contracts with major retailers like Walmart, contributing to the company's growth and success.

The company diversified its business by winning contracts with schools and other institutions. Furthermore, AAON's focus on high-efficiency HVAC systems tailored for sectors like education and healthcare has contributed to its innovation leadership.
