The History of Harster Heating & Air Conditioning

Posted on January 30th, 2020

We’ve got a long history in south St. Louis. Our company was started by my dad, Emil F. Harster, in 1950. It was a one-man, one-truck company and it’s grown to 28 employees and 24 trucks today – serving some 20,000 St. Louis Metro residents and businesses.

We’re located in Affton (yup, John Goodman’s hometown), in an historical building that was once my grandfather’s hardware store.

I’ve been the owner, manager, chief cook and bottle washer of Harster since 1986. My philosophy’s always been “the customer’s always right”, and to do good work and to charge a fair price. Funny how some companies just don’t get that. Our customers are loyal because we follow that code. I insist on industry certification and honest, ethical practices. It’s a pretty simple recipe, actually, and one that’s a tradition I hope continues for many more years. Thanks for visiting.
