Expert Ductwork. AI Precision. Pittsburgh Built.
Who We Are
PMX Ductwork has fabricated custom sheet metal HVAC duct fittings in Pittsburgh's Steel Valley since 1997. We serve HVAC contractors, mechanical engineers, general contractors, and facility managers across the United States with precision-fabricated ductwork in any size, material, and connection type.
AI-Driven Design & CNC Manufacturing
Our parametric 3D design engine generates exact geometry for every fitting in real time. Specify your dimensions, material, gauge, and connections—and see a full 3D model, CAD drawing, and instant price before you order. Voice input lets you describe your fitting in trade language and our AI configures it automatically. Every fitting is CNC-cut on plasma and laser tables, formed on precision brakes, and inspected before shipping.
What We Fabricate
We manufacture 12 types of duct fittings: straight duct, round duct, square-to-round transitions, elbows, tees, transitions, reducers, return boots, offsets, wyes, end caps, and cross fittings.
