Shop Capability

From the shop floor to the jobsite.

Commercial mechanical work rarely arrives in standard sizes. Equipment connections, existing conditions, and building layouts often require components made specifically for the work in front of the crew.

Seneca fabricates custom HVAC sheet metal in Nolanville for our own projects and for outside customers, including contractors, smaller HVAC shops, facility teams, and commercial businesses across Central Texas.

    Custom HVAC ductwork

  • 02

    CNC plasma cutting

  • 03

    Sheet-metal cutting and forming

  • 04

    Fittings and transitions

  • 05

    Rectangular and round components

  • 06

    Project and field support

Shop Equipment

Precision starts with the right equipment.

CNC cutting technology, dedicated forming equipment, and hands-on shop work move an order from confirmed requirements to finished HVAC components.

Production-ready workspace

Material handling, layout, forming, and inspection happen within one organized fabrication workflow.

Applications

Fabrication for real-world HVAC requirements.

Custom pieces support new construction, equipment changes, renovations, repairs, and the field conditions that standard catalog components cannot resolve.

  • 01Supply and return-air ductwork
  • 02Plenums
  • 03Equipment transitions
  • 04Elbows and offsets
  • 05Reducers and adapters
  • 06Ventilation components
  • 07Replacement and retrofit pieces
  • 08Custom field-fit fittings

Why In-House Matters

Better coordination. Better fit. Fewer delays.

Outside customers can work directly with a local fabrication team. On Seneca-installed projects, shop and field crews can resolve questions before they become jobsite problems.

  • Greater control over fabrication schedules
  • Components made for project-specific conditions
  • Direct communication with a local shop
  • Fewer handoffs between fabrication and installation
  • Consistent workmanship across the order
  • One accountable team for Seneca-installed work

From Requirements to Handoff

A clear path through the shop.

The sequence stays practical: confirm what is required, produce it, check it, and coordinate the next step.

  1. 01

    Review the requirements

    Start with the intended component, project conditions, measurements, quantities, and schedule.

  2. 02

    Confirm dimensions and inputs

    Resolve the information the shop needs before material moves into production.

  3. 03

    Cut and form

    Use in-house cutting, bending, and forming equipment to produce the required pieces.

  4. 04

    Assemble and inspect

    Prepare components for their next step and check them against the confirmed requirements.

  5. 05

    Coordinate the handoff

    Align pickup or Seneca installation with the customer and the project schedule.
