Backup Power You Never Have to Second-Guess
A standby generator only earns its keep in one moment, and that is the moment the lights go out. Whether the grid buckles under a triple-digit August afternoon or an ice storm knocks out power across the Hill Country, your generator needs to start without hesitation.
Hunter Service Group Electrical, Heating, & AC Repair is San Antonio’s #1 Generac-certified dealer, and our Generator Membership is designed to ensure your unit is always ready for that moment. It is a straightforward plan that puts your generator on a regular care schedule with a local, family-owned team that treats your home like it belongs to someone we know.
Why Generator Maintenance Matters
Most of a generator’s life is spent sitting still. During those quiet months, batteries slowly lose their charge, fuel breaks down, and connections corrode where no one can see them. None of that announces itself until an outage forces the unit to fire up under full load.
San Antonio’s climate speeds up that wear. Months of intense heat are tough on engine components, while the humidity that drifts up from the Gulf steadily eats away at wiring, terminals, and metal housings year-round.
Scheduled maintenance catches these problems while they are still small and inexpensive to fix. Instead of finding out something is wrong during a blackout, you find out during a routine visit, on your terms.
- Minor wear gets fixed early.
- Stress on the engine drops.
- Unit lasts longer
- Warranty stays protected
- Readiness confirmed before outages
That kind of consistency protects your investment, your budget, and your family’s comfort when the power grid does not cooperate.

Because we are electrical contractors first and foremost, our technicians understand your generator from the transfer switch to the final connection. That background means every service visit goes beyond a quick once-over.
