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

Home standby generator installation is priced by an on-site quote; total cost varies with generator size, fuel setup, transfer switch, and site conditions. Sizing (kilowatts) is the biggest driver because larger units and any needed electrical upgrades add equipment and labor. A right-sized unit that starts your furnace and well pump often costs less than oversizing for every outlet. Final pricing is confirmed after an in-person assessment. Our electricians install Generac systems around the Roberts area with code-compliant clearances and verified fuel supply.

Expect these factors to set your price:

• Load plan: whole-house vs essential-circuits based on a technician’s kW calculation.
• Fuel: natural gas or propane line and tank sizing to meet demand.
• Transfer equipment: ATS type and how it integrates with your panel.
• Site work: pad location, conduit or gas trenching, and snow-clearance spacing.

Schedule a load and fuel assessment so we can provide a firm, itemized quote.
