Our story stretches back to the early 1900s when A.H. Knoettner started a plumbing, heating, and sheet metal business. Later, his sons joined him, and together they built a large-scale operation with about 200 employees and 55 trucks that reached 5 states. As local plumbing professionals, they identified a need for a supply company that was conveniently located and could save tradespeople a congested trip into the city. A supply company that was easier to access, but would carry everything that you could need. 

By the early 1920s, the “Audubon Firm” dream had been realized. Our plumbing services were discontinued as well, allowing us to focus completely on supplies. 


Fast forward to today and Audubon Supply Co. is a fourth-generation, family-owned business. We still offer plumbing, HVAC, and sheet metal services, with two dedicated fabrication shops that meet the needs of countless local HVAC and plumbing professionals.
