What Is a Whole-Home Generator?

A whole-home generator is a backup power system that automatically provides electricity during an outage. Unlike portable generators, it connects directly to your home’s electrical system and runs on natural gas, propane, or diesel. Whole-home generators ensure continuous power to essential appliances and systems, keeping your home safe and comfortable during blackouts.

How Does a Whole-Home Generator Work?

When the power goes out, an automatic transfer switch detects the outage and activates the generator. The generator then supplies power to your home, restoring electricity within seconds. Once utility power is restored, the system shuts off automatically, ensuring a seamless transition.

What Are the Benefits of Installing a Whole-Home Generator?

A whole-home generator provides uninterrupted power, protecting your home from outages caused by storms, grid failures, or emergencies. It keeps essential appliances, medical devices, and heating and cooling systems running. Additionally, it increases home value and offers peace of mind, especially in areas prone to frequent power disruptions.

What Size Generator Do I Need for My Home?

The right generator size depends on the total wattage of the appliances and systems you want to power. Smaller generators (10-15kW) can run essential systems, while larger models (20-30kW or more) can power the entire home. A professional electrician can help determine the appropriate generator size based on your household’s energy needs.

What Fuel Options Are Available for Whole-Home Generators?

Whole-home generators typically run on natural gas, propane, or diesel. Natural gas provides an unlimited fuel source if your home has a gas connection, while propane is a good option for homes without gas lines. Diesel generators are often used for high-power applications but require fuel storage.

How Long Can a Whole-Home Generator Run?

A whole-home generator can run indefinitely on natural gas, as long as the fuel supply is uninterrupted. Propane or diesel models run until their fuel supply is depleted, with run times depending on tank size. Regular maintenance ensures the generator remains in good working condition for extended use.

Do Whole-Home Generators Require Maintenance?

Yes, regular maintenance is necessary to keep the generator running efficiently. Maintenance includes checking oil levels, replacing filters, testing the battery, and running the unit periodically to ensure proper function. Professional inspections help identify and fix potential issues before an outage occurs.

Should I Hire a Professional to Install a Whole-Home Generator?

Yes, whole-home generator installation involves electrical and gas connections that must meet safety codes. A licensed electrician ensures proper sizing, wiring, and integration with your electrical / electrical -panels/”>home’s electrical panel. Professional installation guarantees safe and reliable operation when you need it most.

Chris Fischer was prompt and very courteous. Very good people skills which seems to be a rarity these days. He explained the problem we were experiencing with our cellar floor drain and his solution to fix the issue. He quoted a price prior to starting any work which I thought was reasonable. He also discovered another plumbing issue and addressed that as well. All plumbing issues were resolved Would highly recommend Chris and there members program.
