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

Installing a home standby generator typically costs $3,000–$35,000 for 10–22 kW systems. Final price depends on generator size (we install 10–28 kW), fuel type (natural gas or propane), site prep, and adding an automatic transfer switch. In Longmont and Boulder, Titus handles Boulder County permitting and NEC 2023 compliance. Most installs finish in 4–8 hours, with outage testing included. Ask about Xcel Energy’s $500 rebate for eligible energy-efficient installations. Annual maintenance helps achieve a 10–15 year lifespan.
