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

The cost to install a home standby generator is set after an on-site evaluation because price depends on generator size, fuel source, electrical scope, and required permits. The most common driver is system capacity (wattage), which affects equipment cost and the transfer switch and gas work required. At Sky Heating, AC, Plumbing & Electrical, licensed electricians handle permitting and code compliance (Building Code 99-110) and verify your panel, wiring, and site before quoting. We complete startup testing so the system is ready when the power fails. Our team regularly installs systems across the Portland metro, including the area around Aurora. A small but real factor we see in bids is that the transfer switch choice often sets both scope and timeline. Electrical members receive 5% off major installations, and current promos list generators in stock with offers advertised as low as $25 (see website for details); final pricing is confirmed after inspection.

Typical factors that change the quote:

• Panel upgrades or service size changes
• Gas piping length, trenching, pad, and placement
• Local permit set and inspection fees
