Why STR
We service what we install — and we install what we service.
Most HVAC firms split into install crews and service crews that don't talk. Ours don't. The tech who shows up to fix your rooftop unit at 2 a.m. has probably worked on the install crew that put it there.
That means faster diagnosis, cleaner repairs, and a service record that actually reflects what's in your building.
- Factory-trained on Trane, Carrier, Daikin, JCI, Lennox, Mitsubishi, and LG
- EPA-certified universal techs on every truck
- Manufacturer warranty handling — we file the paperwork, you don't
- Aligned with your in-house facilities team, not in competition with them
- Same crew for service and projects — no handoff friction
