Our On-Site Sheet Metal Shop


Unlike many HVAC contractors who outsource duct fabrication, we operate our own sheet metal shop right here in Bel Air. That means we can quickly produce custom-fit ducts, plenums, and transitions for any project—including luxury homes with complex layouts, older houses needing unique retrofits, and even light commercial buildings in Phoenix, Jacksonville, and Timonium.


By handling fabrication in-house, we reduce delays, guarantee accuracy, and deliver a level of customization that off-the-shelf duct systems simply can’t match.

Why Choose Custom Ductwork?


Every HVAC system relies on proper duct design to perform efficiently. Our custom fabrication ensures:


  • Better Efficiency – No leaky connections or undersized runs that strain your system and drive up energy costs.
  • Balanced Airflow – Even heating and cooling in every room, including hard-to-condition areas like bonus rooms or additions.
  • Tailored Fit – Perfect for unique architectural designs, historic homes, or large properties up to 10,000 sq ft.
  • Custom Vents and Finishes – Decorative grilles or specialty vents to complement high-end interiors.

Whether you’re replacing an old furnace or upgrading your AC, custom ductwork makes a measurable difference in comfort and energy savings.

Custom Ductwork FAQs

  • Do I need custom ductwork for a new HVAC system?

    Not always, but if your home has unique architecture, additions, or older ducts that don’t meet current standards, custom fabrication can improve airflow and efficiency.

  • Can you design ductwork for very large homes?

    Yes. We regularly create systems for homes up to 10,000 sq ft and beyond, ensuring even comfort across multiple zones.

  • Do you handle ductwork for commercial spaces?

    Absolutely. Our in-house sheet metal shop allows us to fabricate ducts for light commercial properties, including offices and retail spaces.

  • How long does it take to fabricate custom ducts?

    Most residential projects are completed quickly because we fabricate in-house. Timelines vary depending on complexity, but you won’t wait on an outside supplier.

  • Can you replace just part of my ductwork?

    Yes. We can fabricate and install sections to improve specific problem areas, like poorly balanced runs or outdated fittings, without replacing the entire system.
