About Zenner & Ritter

Zenner & Ritter traces its roots to the late 1920s 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, although shortly afterward 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.

Charles H. Ritter grew the company from its humble beginnings into a well-known Buffalo-area heating and cooling business. His son, Charles C. Ritter, assumed leadership of the business in the mid 1980’s. For nearly 30 years, Charles C. Ritter was the driving force behind the business, infusing the company and its employees with his own unique combination of expressive communication and efficient service

Sadly, Charles C. Ritter passed away in 2010, leaving Zenner & Ritter in the capable hands of his wife, Barbara Ritter. Today, Barbara and her son Brian Ritter lead what is now the largest residential heating and cooling company in Western NY. To serve the wider needs of its customers, the company recently launched a new residential plumbing division. And, to stay in front of the available technology, the company is also growing a green products division that will offer products and services, including geothermal heating and cooling, solar heat, and combined micro heat and power systems. Under Barbara and Brian’s leadership, the company continues to evolve, but we will always remain committed to providing the best prices and the friendliest service anywhere!
