HVAC Service Team Member and Co-owner of Heart of America Service Company

Ernie Cooper

Ernie Cooper was born in Vermont. He grew up on a dairy farm and became his grandfather's shadow. It was from his grandfather's influence that his interest in mechanics developed. As he grew up, Ernie found life leading him into college, where he did well, but he couldn't handle sitting in classes all day. In 1973 he married his high school sweetheart, left college, and started working for a landscape company. Ernie's father-in-law owned a Heating and Cooling HVAC Service Company, and in the spring of 1974, he offered Ernie to join his company as an installer helper. Ernie has never looked back.

In college, he pursued degrees in Math and Education with a minor in Geology and Psychology. Gene met and married my wife here in Kansas City in 1984.
