Capabilities

Santiam has been doing commercial HVAC and sheet metal since 1994. GCs, facility managers, architects, building owners — we work with all of them, across Oregon and Southwest Washington. We show up, hit our schedules, and don’t create surprises.

Design/Build

We handle mechanical design and installation under one contract. No gaps between designer and installer.

Plan/Spec

We bid to drawings, coordinate with trades, and deliver on schedule.

Fabrication

Custom fittings, ductwork, and architectural sheet metal. Made here, not outsourced.

Preventative Maintenance

PM programs built around your building type and system complexity.
