Company Details:

Saint Louis, Missouri
In 1950, Emil F. Harster set out on his own with his truck to start Harster Heating & Air Conditioning in south St. Louis, Missouri. Over the decades the company expanded to become the 28-employee, 24 truck company customers see today. Today, Emil's son, Dave, owns and runs the company, a position he's been in since 1986. Dave's philosophy is simple, he believes the customer is always right and aims to provide quality customer service at a fair price.
