Trade focus?

Piping, plumbing, HVAC, and sheet metal foremen on healthcare, mission-critical, industrial, and large commercial scopes throughout San Jose.

Union or open shop?

Both. San Jose clients include union and merit-shop contractors — we match candidates to their preferred environment.

How is data center work different from other commercial HVAC in Silicon Valley?

Sequence-of-operations complexity, chilled-water plant scale, commissioning rigor, and 24/7 uptime constraints. Candidates with hyperscale or enterprise colo experience are 2–3x more valuable than commercial-only backgrounds.
