Standby Generator Installation

A standby generator kicks on within seconds of an outage, on natural gas or propane. We handle the pad, switch, permit and gas coordination.

Signs you need it

  • Over a day without power in the last two years
  • Someone at home relies on medical equipment
  • A well pump, or a freezer full of food
  • You work from home

How the install goes

  1. Size it: whole house or essentials
  2. Set the pad, place the unit with required clearances
  3. Install the automatic transfer switch, coordinate gas
  4. Start it, simulate an outage, walk you through the app

Backup power questions

What size standby generator do I need?

Usually 18 to 26 kW. A load calculation keeps you from overbuying.

Natural gas or propane generator?

Natural gas if you have it. Propane needs a tank but works anywhere.

Do you charge for the quote?

No. An electrician looks at the job in person and quotes it, free.
