Why Kirkwood Homeowners Choose Standby Generators

Many Kirkwood homes date from the 1920s through the 1960s. Kirkwood's older housing stock makes panel upgrades, aluminum wiring remediation, and rewiring especially common here. 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.
