Industrial Capability

We Don't Just Install.
We Build.

500,000 lbs

Of custom ductwork fabricated annually — automated, precision-cut sheet metal

Most HVAC contractors order ductwork from a distributor. We fabricate it ourselves — using automated sheet metal equipment that cuts, bends, and forms custom ductwork in-house. That means faster lead times, tighter tolerances, and lower costs passed directly to you.

  • Automated fabrication for any duct shape or size
  • Serves both residential and large-scale commercial projects
  • Galvanized steel precision-formed to your specs
  • In-house production = faster turnaround, controlled quality

This means better fit, faster delivery, and higher quality than off-the-shelf ductwork.
