Custom Sheet Metal Fabrication

Get the exact ductwork and fittings your HVAC system needs with on-site fabrication.

Not every HVAC job fits standard parts. Sometimes you need a custom transition, a specific size plenum, or ductwork that routes around obstacles in your home. Most contractors force standard parts to fit or leave you with a system that doesn't move air properly. We don't. We fabricate custom sheet metal on-site so your ductwork fits correctly and performs the way it should. Custom fabrication means better airflow, quieter operation, and systems that last longer because they're not fighting against poorly fitted components.

We handle all types of sheet metal work, from simple duct transitions to complex plenum boxes and custom grilles. Whether you're adding HVAC to a new addition, replacing old ductwork that's falling apart, or upgrading a system that's never worked right, we build the parts you need. That includes measuring, cutting, forming, and installing sheet metal that matches your system's specifications. We also repair existing ductwork by fabricating replacement sections for damaged or poorly designed parts.

When you call Northern HVAC for sheet metal work, you're getting someone who's been fabricating ductwork for five years. We have the tools and skills to build custom parts that fit right the first time. Call us and get ductwork that actually works.

Why Choose Northern HVAC for Custom Sheet Metal Fabrication

Built to Fit, Not Forced to Fit – We measure carefully and build parts that fit your system exactly. No gaps, no forcing connections, no compromises that cause air leaks.
Better Airflow & System Performance – Properly fabricated ductwork moves air efficiently and quietly. Poor fitment causes whistling, reduced airflow, and uneven heating or cooling.
On-Site Fabrication Saves Time – We build parts at your home instead of ordering custom pieces and waiting for delivery. Most jobs get completed in one visit.
Five Years of Fabrication Experience – We've been building custom sheet metal for HVAC systems since we started. We know what works, what doesn't, and how to make parts that last.
No Compromises on Quality – We use proper materials, proper techniques, and proper fasteners. Sheet metal work that's done right doesn't leak, doesn't rattle, and doesn't fall apart.
