Generac 22kW Guardian Generator Installation & Pricing in Ohio

Whole-house backup for most Ohio homes, installed start to finish by Generator One, a Generac Power Pro Prestige dealer.

Model Overview

The Generac 22kW Guardian, Model G0070420

The 22kW Guardian is the size Generator One most often recommends for whole-house backup in Ohio: enough for a typical home below 3,000 square feet with a single central AC. When the utility fails it starts by itself in seconds, fueled by the gas or propane line the house already has.
