How much does it cost to install a standby generator at home?

The cost to install a home standby generator is confirmed after an on-site assessment with an upfront, written estimate, because pricing depends on the generator and the work needed to connect it safely. The biggest driver is the generator’s size (kW) matched to your home’s essential or whole‑home power needs.

As a Generac certified dealer, Appleton Campbell also handles the necessary gas line work, which can change scope and labor. Our licensed team installs and maintains systems throughout the Bristow area with one‑contractor convenience and clear pricing, and financing and free estimates are available.

Key factors that change total price:

• Generator capacity and model selection
• Scope of any required gas line work
• Transfer switch type plus any panel upgrades or whole‑home surge protection
• Installation complexity at your home (placement, clearances, and routing for connections)
