Makers of Stainless Steel HVAC Air Distribution Products

Founded in the mid-1920s, AJ Manufacturing has always been in the sheet metal product business. During and immediately after World War II, AJ Manufacturing was once the nation’s largest residential and light commercial manufacturer.

In 1974, AJ began specializing in the HVAC industry, particularly in the stainless steel production of custom commercial HVAC supply grilles, HVAC return grilles, registers, and diffusers. This specialization continues to today, as AJ Manufacturing remains a mainstay in the HVAC industry, with products featured in hospitals, laboratories, and commercial buildings.
