Zenner & Ritter Inc.

Charles H. Ritter and his partner, Arthur Ritter, went door-to-door in the late 1920s promising to clean coal dust out of ductwork and furnaces. Bill Zenner entered the company as Charles' business associate but left to run a nearby hardware store shortly after. Zenner & Ritter is the name of the best HVAC contractors in Buffalo, NY for heating and cooling services.
