Standby Generator Installation in San Antonio
A standby generator senses the outage, starts itself, and carries your home until the grid comes back — no cords, no gas cans, no being home for it. We size, permit, install, and maintain them across the San Antonio metro from our shop in Converse.
Done with the dark?
Your house, not a brochure.
Generator sizing is a load calculation: what must run, what can shed, and what your gas service can actually supply. Undersized generators trip under real load; oversized ones cost more to buy and run. We do the math on your panel and your meter before recommending a unit — and we’re factory-certified on Generac’s current standby line.
Permits, gas, and inspection — handled.
A standby generator involves your electrical panel, a transfer switch, and a fuel connection — work that requires a licensed electrical contractor and city permits in the San Antonio metro. We run the whole process under TECL #35881: permit, placement per code clearances, transfer switch installation, and inspection. Natural gas and propane installs both supported.
From sizing to self-start.
San Antonio generators, answered.
What size generator does my house need?
It depends on what you want to run — a load calculation on your actual panel answers it. Whole-home and essentials-only are both valid designs.
Natural gas or propane?
Either. Most San Antonio homes with gas service use natural gas; propane suits homes without it. We’ll confirm supply capacity before sizing.
Do I need a permit?
Yes — generator installs involve permitted electrical and fuel work. We pull the permits and handle inspection.
How is this different from a battery?
A generator runs as long as it has fuel; a battery is silent and instant but finite. For many homes the honest answer is one, not both — we’ll show you the comparison.
Will it start when I’m not home?
Yes — standby units self-start on outage and self-test on a schedule. A maintenance plan keeps that reliable.
