Why Ballwin Homeowners Choose Standby Generators

Most Ballwin homes were constructed between 1970 and 1995. Homes built in the 1970s–80s — common throughout Ballwin — often have original 100A panels that can't support modern electrical loads. 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.
