Zenner & Ritter Inc

Zenner & Ritter traces its roots to the late 1920’s when Charles H. Ritter and his brother, Arthur Ritter, went door-to-door offering to clean coal dust out of duct work and furnaces. Bill Zenner, joined the business as Charles’ business partner though shortly after, he left to manage a local hardware store. At that time, the company was well-known as Zenner & Ritter and has kept both names ever since.
