Featured Project — Greater Pittsburgh Area
Custom Sheet Metal Ductwork Fabrication & Installation — Monroeville, PA
Commercial and industrial facilities in the Greater Pittsburgh area demand more than off-the-shelf ductwork. When a commercial client in Monroeville, PA needed a complete custom sheet metal duct system for a light industrial space, Heirloom Mechanical designed, fabricated, and installed every piece in-house — from the trunk runs and transition fittings to the equipment room ventilation hoods and exterior wall penetrations.
The project required precision-fit ductwork to serve industrial air compressor equipment, with custom plenums and exhaust hoods fabricated to exact dimensions. Our sheet metal work is cut, formed, and assembled by our own technicians — not subcontracted — so every seam, fitting, and connection meets the performance and code requirements your facility demands.
- Custom sheet metal ductwork fabricated on-site
- Industrial equipment room ventilation hoods
- Trunk runs, transitions, and plenum boxes
- Exterior wall penetrations and louver installation
- Full system design, fabrication, and installation
- Serving Allegheny County commercial & industrial clients
