How Do Backup Generators Work?

During an outage or shortage, a permanent backup generator will power your home’s most essential systems, keeping you safe and comfortable. Unlike portable generators that require manual setup, a standby system will detect a power interruption and automatically transfer your home to generator power. When utility power returns, the system automatically switches back. Standby generators can also operate while you are away, protecting your home even when you cannot be there.

Backup Generator FAQs

Can A Generator Power My Whole House?

A properly sized whole-house generator can support your home’s electrical needs during an outage. Generator capacity is based on the wattage requirements of the appliances and systems you want to operate.

What Fuel Does a Standby Generator Use?

Roman Home Services installs standby systems that operate on natural gas or propane. Your home's available fuel supply and your generator's requirements will help determine the appropriate option.

How Often Should a Generator Be Serviced?

We recommend annual maintenance for your generator. Usually, this translates to 100 to 200 hours of use. If your generator has operated for longer than that period within one year, it’s best to call us for a maintenance visit. By investing in proactive services, you can make certain that your generator is operating effectively when you need it the most.
