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.

I woke up to a freezing house..thermostat reading 42°, the boiler cold & silent. I’ve used Roy’s in the past & from beginning to end everyone is always friendly and professional. From the woman who took the-initial call, caring enough to ask questions so she could schedule the technicians who had the expertise & experience working with older steam boilers. Mike & Gabriel diagnosed the problem,,replaced the part & had it up and running in no time at all. They were both , personable, professional, & knowledgeable.

All of the crew were very well mannered, educated in their craft, and completed the job in a timely fashion. It started out with a clogged sewer pipe and ended up with new piping. I have dealt with them on and off for a couple months and have always had a pleasurable experience And an honest one in regards to prices and quotes. I highly recommend them.

The previous owners had Roy’s install the hot water heater. It finally died on Sunday and they came out the next day. Within 48 hours of coming home to water leaking out, we had a whole new setup! All the technicians were great to work with, very clean. Impressed with their install, price and warranty.

We had to make an emergency service call recently for a major clog in our plumbing that was causing a huge backup and water to come down from our second floor bathrooms, inside the walls, through our ceiling and vents, and ultimately down to our basement. Needless to say it was a mess and a very stressful situation. We were able to get a same day appointment and Josh B showed up. He was amazing. He was not only polite and friendly, and reassured us with his credentials and experience - but did a thorough job identifying and explaining the issue. He was able to get everything fixed for us, and all with a smile and friendly attitude, despite it being a challenging last call of the day on a Friday. I would never hesitate to call Roy’s again for any plumbing needs, and while I’m sure everyone there is great, I’d request Josh again with confidence.
