James Explains Jon Wayne Generators


Cost to install a home generator:

  • Low$8,900
  • Average$18,000
  • High$27,900

What affects cost?

The cost to install a whole-home generator depends on several factors, including:

  • Number of appliances you want to power. The more appliances you want powered during a power outage, the more powerful your generator will need to be–and more powerful generators cost more.
  • Adding a concrete slab. Depending on your local codes, you may need to pour a concrete pad for your generator. This will increase your overall costs.
  • Whether you need an upgraded gas meter. Sometimes, a gas generator will need larger gas meters than what the home currently has. If you need to upgrade the gas meter, this will increase costs.
  • Company you hire. You’ll pay more for skilled, experienced techs who knows how to properly install your whole-home generator.
