Why South City Homeowners Choose Standby Generators

South City homes were largely built between 1900 and 1950 — some of the oldest housing stock in the metro. South City has the oldest homes in the St. Louis area, with knob-and-tube wiring, two-prong outlets, and 60A to 100A panels that are decades overdue for attention. St. Louis storms — ice storms, severe thunderstorms, and the occasional tornado — can knock out power for days. A permanently installed standby generator means your heat, AC, refrigerator, sump pump, and medical equipment keep running automatically, regardless of what's happening outside.
