Linda C.Home Standby Generator FAQs
Answers to the questions Southeastern Wisconsin homeowners ask most about Generac standby generators.
What size generator do I need for my home?
Generator sizing depends on what you want to power: essential circuits only or your whole home, including central air, well pumps, and electric appliances. Southeast Electrical Services performs a load assessment during your free estimate and recommends the right Generac model and transfer switch for your home.
How does a home standby generator work?
A home standby generator is permanently installed outside your home and connected to your natural gas or propane supply. When the utility power goes out, the automatic transfer switch senses the outage and starts the generator within seconds. When utility power returns, it switches back and the generator shuts down on its own.
Can a standby generator run on natural gas or propane?
Yes. Generac home standby generators run on natural gas or liquid propane (LP). Natural gas provides a continuous supply from the utility line, while propane runtime depends on the size of your tank. We'll help you choose the best option for your property.
Will a standby generator work in a Wisconsin winter?
Yes. Generac standby generators are built for outdoor use in all seasons, and cold-weather accessories such as battery warmers are available for extreme temperatures. Regular maintenance before winter helps ensure your generator starts reliably when you need it most.
How long does a home standby generator installation take?
Most installations are completed in one to two days once permits and utility approvals are in place. Timing depends on site preparation, fuel line work, and local inspection schedules. We coordinate every step and keep you informed from start to finish.
Where can a generator be placed or installed?
The generator is installed outside your home, typically close to your fuel source (propane tank or natural gas meter) and electrical service. We perform a site survey to choose a location that meets Generac's installation requirements and local code clearances from windows, doors, and vents.
Do generators have to be maintained?
Yes. Like a car, a generator needs periodic maintenance such as oil and filter changes, spark plug and battery checks, and software updates. We recommend professional service at least once a year, and our factory-trained technicians can keep your Generac running at peak performance.
