What We Do
Complete Generator Services
Generator Panel & Load Calculation
We size your generator correctly by calculating your home's critical loads — HVAC, refrigerator, medical equipment, lighting — so you're never under- or over-powered.
Generator Maintenance & Repair
Annual tune-ups, load bank testing, oil changes, and troubleshooting for all major generator brands. Keep your backup power ready when you need it most.
Emergency Generator Service
Generator not starting during an outage? Our technicians provide emergency diagnostic and repair service to get your power restored fast.
Portable Generator Hookup
Safe, code-compliant manual transfer switch and inlet box installation for portable generators. Eliminates the risk of backfeed and protects utility workers.
Automatic Transfer Switch (ATS)
ATS installation ensures your generator kicks on the moment utility power fails — no manual switching, no extension cords. We install and wire transfer switches for all generator brands.
Standby Generator Installation
Permanent whole-home standby generators that start automatically within seconds of a power outage. We handle site prep, gas line coordination, and electrical connection.
