Since 1984
Designed, built, and commissioned by the same team — no handoffs, no finger-pointing.
HVAC and Building Automation, San Dimas, California.
Built For
The general contractor who wants a mechanical scope that lands clean.
The facility manager who’d rather have the Building Automation calibrated by the people who installed it.
The owner who’d rather keep one name in their phone for forty years than chase the lowest bid every two.
Athena Engineering self-performs HVAC, Building Automation — and General Contracting when we run the prime. Across Southern California. San Dimas, since 1984.
What We Do
Three lines of work. One team behind all of them.
Self-performed in-house — from design through commissioning and service. No subbed-out scopes hiding in the middle.
Building Automation
Schneider EcoStruxure, JCI Facility Explorer, Argus, plus access control. Legacy migrations without the rip-and-replace. One team, design through service.
Mechanical
HVAC, piping, sheet metal, and service. Self-performed in-house since 1984, across new construction and retrofits.
General Contracting
Tenant improvements, modernizations, and public-sector prime work. The trades that drive the schedule are in-house.
Where We Work
Forty years across the markets that can't afford downtime.
Healthcare, civic infrastructure, education, utilities — and the rest of Southern California's working buildings.

The controls were a one-time install. Keeping them tuned is a relationship.
Service contracts, troubleshooting, and recommissioning for Schneider EcoStruxure, JCI Facility Explorer, and the open-protocol systems in between. For the buildings we installed — and the ones we didn’t.
Working Here
Most of our team has been here longer than the last office space.
Field and office. Union sheetmetal (SMART Local 105). Union work in Building Automation. Programmers, engineers, estimators, office — hiring all of it.
