Whole-home generators in Charleston, WV

Winter storms and summer thunderstorms knock out power across West Virginia. A standby generator starts on its own within seconds of an outage and keeps your furnace, well pump, sump pump, and fridge running.

What we do

  • Whole-home standby generators with automatic transfer switches
  • Load calculations so the generator fits what you need to run
  • Manual transfer switches and interlock kits for portable generators
  • Natural gas and propane connections
  • Annual maintenance, load testing, and repairs

Common questions

Can I plug a portable generator into an outlet?

No. Back-feeding through an outlet can energize the utility line and injure line workers. A transfer switch or interlock kit is the safe, code-compliant way to connect.

How often does a standby generator need service?

Once a year is typical: oil, filters, battery check, and a load test.

Lost power or smell burning?

Licensed electricians on call 24 hours a day, 7 days a week.
