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

The cost to install a home standby generator is finalized after an on-site assessment because generator size, fuel source, and electrical upgrades determine the price. The largest driver is usually kW sizing and the automatic transfer switch work needed to start the unit and carry your peak loads safely. Dawson's Electric & Air provides upfront pricing after we review your panel and circuits, and financing options are available if you want to spread payments. We install code-compliant systems in the Morrisville area and handle all required permits and inspections.

Key factors that shape your total project cost:

• Generator capacity (many homes land around 20–24 kW) and any brand features
• Installation scope: full-home coverage vs critical-circuit setup and ATS type
• Electrical work: panel modifications or replacement to integrate the ATS
• Fuel and placement: natural gas or propane connections, concrete pad, and run length

An in-home load review and site visit is the fastest way to receive an accurate, no-surprise quote.
