What Is a Whole-Home Generator and How Does It Work?

A whole-home generator automatically powers your home during a utility outage. It connects directly to your home’s electrical panel and typically runs on natural gas or propane. Within seconds of losing power, it kicks on to keep lights, appliances, and HVAC systems running.

How Is a Whole-Home Generator Different From a Portable One?

Whole-home generators are permanently installed and can power your entire home automatically. Portable generators require manual setup, limited fuel, and only support select appliances. The convenience, safety, and capacity of whole-home systems make them ideal for long-term reliability.

What Size Generator Do I Need for My Home?

The right size depends on your home’s square footage and the appliances or systems you want to power. Most homes need a generator between 14–22 kilowatts for full coverage. A licensed electrician can calculate your exact power needs and recommend the appropriate model.

Does a Whole-Home Generator Turn On Automatically?

Yes, whole-home generators have automatic transfer switches that detect outages and start the generator within seconds. This ensures continuous power without you needing to lift a finger. When utility power returns, the system shuts off and switches back seamlessly.

Can a Whole-Home Generator Power My HVAC System?

Absolutely—one of the major benefits of a whole-home generator is its ability to support high-demand systems like air conditioning and heating. This keeps your home comfortable even during extended outages. Make sure the unit is sized correctly to handle your HVAC load.

How Often Does a Whole-Home Generator Need Maintenance?

Most generators should be serviced at least once a year, or after every 100–200 hours of use. Regular maintenance includes oil changes, filter replacements, and system checks. Many systems also perform self-tests weekly to ensure they’re ready when needed.

Is a Whole-Home Generator a Good Investment?

Yes, especially in areas with frequent storms or unreliable power. It protects your food, electronics, and comfort while also increasing your home’s value. Many homeowners find peace of mind alone makes it worth the investment.

What Fuel Types Can Be Used for Whole-Home Generators?

Whole-home generators typically run on natural gas or propane, with some models also supporting diesel. Natural gas is convenient if your home already has a line, while propane is great for rural areas with large storage tanks. The fuel choice affects installation and operating costs.

We had a massive water leak at 7:00 pm two nights ago, literally right after having our crawl space professionally encapsulated. We made one phone call to Ted’s and Nathan and Levi were there within an hour. Not only did they get there quickly, they also shared multiple options with me and were able to get my water back on in no time. I have them coming back in two weeks to install a water filtration system. Thank you Levi and Nathan for the 5 star experience.

Ted’s recently replaced my HVAC, duct work and upgraded my electrical. They always showed on time, communicated well, were professional and clean. Ted even came out himself and added an additional outdoor outlet for us, with no charge. So incredibly grateful to support this local business in Roxboro. Kendall came out to our home another time for some installs and was quick, communicative and professional.
