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.

Noah arrived on time to replace my water heater. He was polite and explained the process in detail. He was patient and thorough. This replacement was a tough one. He cleaned up and took the time to make sure I understood what was done and what I needed to know about my new water heater. Answered my questions and reminded me to make sure I take advantage of my maintenance membership. I have used Roy’s services a few times for big jobs and their prices are better than most and the service has been amazing. I trust them with my home needs. Thanks Noah for being so awesome!

Josh B. Did an excellent job today with an issue I have had for a few years. Pro chain cleaning was recommended, and it did the trick. Would suggest this method for stubborn clogs that develop in longer drain lines where a standard diameter snake doesn’t work.

Needed to have kitchen/laundry room plumbing looked at due to a clog that persisted to happen every 2-3 years with build up. Other companies typically will just snake it & move on. Roy's took the time to get to the root of the issue & re did the plumbing lines so hopefully it will not happen again. From the diagnoser to the installer, the whole team was quick, efficient, & friendly!

Great service. The technician (Ryan) was awesome. He arrived literally within minutes of the service call ( he was finishing a job in my neighborhood) quickly diagnosed my furnace issue and made repairs within an hour. I was charged what I feel is a fair price to do something I couldn't have done myself. The replacement parts come with a warranty. Couldn't be happier. Now the wife won't yell at me because the house is freezing. Good experience all around

Had my kitchen sink snaked. They couldn't get it done the first day but they came back the next day and cleared up the clog. Sean is highly professional and very concerned about fixing my problem. I will always call Roy's any future heating and plumbing work. And I will ask for Sean.

Steve Martin was my tech today and he was absolutely outstanding! His knowledge of steam boiler systems is impressive, and he explained everything clearly and professionally from start to finish. He took the time to thoroughly inspect and tune up the system, making sure everything was running efficiently and safely. You can tell he truly knows his craft and takes pride in his work. The tune-up was done carefully and meticulously, and I really appreciate his professionalism, attention to detail, and willingness to answer questions. Highly recommend Steve to anyone looking for a knowledgeable and reliable tech!

I was in urgent need of a new sump pump. I called in the morning and got an appointment right away. They were able to come even earlier than expected, which was great! Josh B. went through all my options with me at every price point and didn't pressure me into any decision. He said he wanted to treat me like family and made sure I made an informed decision. When I gave him the go ahead, he finished the work in about an hour and then walked me through what he did and how I should handle the upkeep. I went from being panicked to put at complete ease in just a few hours. Thanks Josh B! Great Job!
