Generator Installation: What It Costs and How to Choose a Provider

What's included

Load calculation and sizing, equipment placement and mounting, electrical wiring to an automatic transfer switch, gas-line hookup (natural gas/propane) or fuel-tank setup, permit filing and inspection coordination, and startup testing.

Typical cost

$3,000–$5,000 in labor alone, on top of the $2,000–$10,000+ generator unit itself.

How to choose

Confirm the installer is licensed in your state, ask whether they handle permit filing directly (many don't, which shifts that burden to you), and get the load calculation in writing before agreeing to a unit size.
