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 couldn’t recommend Josh Butry enough! I’ve been in my home for almost 2 years and it has been nothing short of frustrating and exhausting the amount of repairs I’ve had done. I went to Roy’s last year when my water boiler died and didn’t have a second thought when I had a leak in the same room. I’ve been anxious over this issue since I made the appointment but Josh made the experience as seamless as possible. Josh was thorough in explaining what could have happened, what actually happened and what the next steps were! I feel lucky that it was a “small” issue and he was able to fix it in the same day! He also gave me recommendations moving forward! I will definitely be requesting Josh as my preferred plumber!

Aaron came out the next day from my call. My AC was blowing hot air when it was 92 degrees outside 😩, he came right on time and immediately took care of the problem, when he left we were nice and cool. Aaron was very professional and friendly, he explained everything that needed to be done and gave a price before he did the work.
Highly recommend this company and Aaron.
