Custom Ductwork & Sheet Metal Fabrication in Philadelphia

Improve HVAC performance and indoor comfort with precision-designed ductwork built by Lefty’s Heating & Air Conditioning. Serving Philadelphia with expert fabrication.

Why Custom Ductwork Matters

Ductwork isn’t one-size-fits-all. Poorly designed or leaky ducts reduce your system’s efficiency and increase energy costs. At Lefty’s, we design and fabricate custom sheet metal ductwork that maximizes airflow and system performance.

We design for:

• New HVAC system installations
• Historic homes and retrofits
• Multi-zone climate control
• Commercial buildings and additions

All components are fabricated in-house and installed by trained technicians to ensure a perfect fit.
