Frequently asked

Is $9,000 a fair price for whole-home standby generator installation in Texas?

Yes. $9,000 is right around what most homeowners in Texas pay. Anything from $3,120 to $16,720 is inside the normal range for a licensed electrician; above $16,720 it is worth getting a second quote.

Why do quotes for the same job vary so much?

Generator size: a 22–26 kW unit costs thousands more than a 14–18 kW unit. Gas supply: extending a natural-gas line or adding a propane tank is often the biggest variable. Company overhead matters too: a large company with trucks, dispatchers and a warranty department charges more than a one-person shop, and both can be honest prices.

When should I get a second quote?

Any time a quote lands above $16,720, or when the contractor cannot break it into parts, labor and fees. Ask for the itemized version, ask what would change the price, and confirm licensing and insurance. You can also paste the quote into the free QuoteJury checker for an instant second opinion.
