Frequently Asked Questions

Common questions about costs and estimates for this service.

Most whole-home generator installations in Marietta, GA, typically take between 1 to 3 days to complete, depending on the complexity of the job and local permitting requirements.

A portable generator is a movable unit that you manually start and connect to specific appliances. A whole-home standby generator is permanently installed, automatically starts when power is lost, and can power your entire home or selected circuits without manual intervention. Portable options fall into the basic tier ($1,500–$4,500), while whole-home units are typically mid-range to premium ($4,500–$30,000).

For whole-home standby generators, an automatic transfer switch (ATS) is crucial. It senses a power outage, safely disconnects your home from the utility grid, and connects it to the generator. This ensures seamless power restoration and prevents back-feeding electricity into the grid, which can be dangerous. The cost of an ATS is usually factored into whole-home generator system pricing.

Generac and Cummins are widely recognized and popular brands for whole-home generator installations in Marietta, GA. Many local installers specialize in these brands due to their reliability and availability.

While it's possible for some homeowners to self-install smaller, portable generators (potentially keeping costs around $1,500), installing a whole-home standby generator involves complex electrical and gas line work. Professional installation is highly recommended to ensure safety, compliance with local codes, and proper operation of the unit. Unlicensed DIY installation could also void warranties or lead to dangerous situations.
