A home standby generator quote typically includes the generator unit, automatic transfer switch, installation labor, electrical work, fuel connection requirements, and any needed site preparation. Depending on your home, the quote may also include permitting, inspection-related costs, and optional accessories. A detailed quote helps you understand the full project cost before moving forward.
After you submit a quote request, an authorized installer will review your information and contact you to learn more about your home’s backup power needs. In many cases, the next step is an in-home consultation or site evaluation so the installer can recommend the right home standby generator and provide a more accurate quote.
An in-home consultation is a visit from an authorized installer to assess your backup power needs, budget, and installation requirements. During the visit, the installer reviews your electrical load, available space, fuel source, and other site conditions to help determine the right standby generator for your needs and your budget.
Before purchasing a home standby generator, consider the size of your home, the appliances you want to back up, your available fuel source, installation space, and your budget. It also helps to think about whether you want whole-house coverage or backup for only selected circuits. These details help ensure you choose the right generator for your home.

Depending on your home, the process may also involve permits, inspections, and site preparation. Your installer will outline the steps and timeline before installation begins.
Installation timelines can vary based on permitting, site conditions, equipment availability, and utility coordination.
