Standby Generator Installation across Georgia

Standby Generator Installation in Atlanta, GA

Atlanta's tree canopy brings down lines during summer storms and ice events, and outages can last days in wooded neighborhoods. Many homeowners install natural-gas standby generators with automatic transfer switches sized to run the whole house, and the gas company may need to upgrade the meter.

Older in-town bungalows often have mixed wiring from several renovations. Fast suburban growth brings a steady stream of EV chargers, basement finishes and panel upgrades.

Standby Generator Installation in Augusta, GA

Hurricane Helene left most of Augusta without power in September 2024, some homes for two weeks or more in late-summer heat, and standby generators have become far more common since. A natural-gas or propane unit with an automatic transfer switch, sized to run central air, is the usual choice for families with older relatives or medical equipment.

Historic homes in Summerville and Olde Town can have knob-and-tube or cloth wiring, and mid-century homes often have 100 amp panels. Mature trees mean frequent storm damage to service drops. Raised homes are common in older areas.

Standby Generator Installation in Savannah, GA

Hurricanes Matthew in 2016 and Irma in 2017 left Savannah homes without power for days, and low-lying areas near the marsh flood at the highest tides. Standby generators with automatic transfer switches should sit on raised platforms above the flood elevation, in enclosures built for salt air.

Historic homes often have wiring from many eras, and the historic district's review board regulates visible exterior changes such as meters and equipment. Outdoor equipment near the marsh and water corrodes faster in salt air.

Standby Generator Installation in Marietta, GA

Ice storms like January 2014's and summer storms that drop trees across north Cobb have left Marietta-area homes without power for days. Natural-gas standby generators with automatic transfer switches are a popular choice in East Cobb and the neighborhoods near Kennesaw Mountain, and the gas meter may need upgrading for a whole-house unit.

Historic homes can have knob-and-tube or cloth wiring, and mid-century homes often have 100 amp panels. Newer subdivisions add EV chargers and generators.

What standby generator installation involves

Unlike a portable generator, a standby unit sits on a pad outside the home, runs a self-test each week, and takes over within seconds of an outage without anyone being home. It can power selected circuits or, if sized for it, the whole house including central air.

Installation combines electrical, fuel and site work: an automatic transfer switch at or near the panel, a gas line or propane tank sized for the unit, and a placement that meets the manufacturer's and local code clearances from windows, doors and property lines.
