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.

Fiushed my water heater. Done a great job. Very polite. Had to call Roy's. My basement water coming up the drain. Josh B came out. Josh and Eric B.jetted my clean out pipe. Found my sewer had dropped six inches. Which means had to dig up and get sewer rerouted. Josh did an excellent job laying out what needed to be done. Plus had to relocate my sump pump drain. Got everything together. Next day the whole team came out and got started. One crew in basement. Other crew outside. What a BIG job. They all worked together. Everyone of the guys were great. If I could give them 10 stars I would. You want a job done the right way. Call Roy's plumbing.

Josh B came out to my house to provide an estimate for a few projects. Off the bat, he was professional and explained his background which instilled my trust in his expertise. He was patient when I asked a bunch of questions and gave some advice on items that we didn’t necessarily need to hire him for. The icing on the cake was that he brought in my recycling bin from the street! My husband and I will be using Roy’s for our garage project because of how great Josh was. Highly recommend!

I had Josh B. And Owen A. as technicians to check out a leak under my sink. Super chill guys. They gave me plenty of options of how to go about the repair including how to go about doing it myself. I heard the usual sales pitch but never felt pressured into anything. Definitely recommend them.

Josh Butry was very professional, thorough, and spoke in a way that I could easily understand how the repair would be made. Roy’s is my first call for plumbing issues.

Christian came on time and was very personable but professional. We had a leak from the bathtub down into the kitchen. We thought it was a pipe leak but after asking a few questions and some assessment, Christian determined it was simply water running behind the water spout and on/off plate which was not caulked properly. An easy fix, and the cost was minimal at $22.00 since we have a Roy’s membership. We are very appreciative to Christian and all the technicians helping us improve our home.

Nick, replaced the pressure reducing valve in the house after a water main break down the street caused it to fail. He tested & checked all the possible causes & solutions (the valve failed). He also called for help for an unrelated mini-split issue of one unit humming. Nick is very professional, certious & knowledgeable about his job, and I would recommend Roy's to anyone.
