Whole-house generators protect you during power outages.
That means your refrigerator will keep running—you won’t have to throw away half of your groceries. Your lights will stay on—hold those candles for the next romantic dinner! Also, the Wi-Fi will keep working.
Your heating and cooling system won’t miss a beat either so you can stay comfortable. Your sump pump will remain powered so that you can avoid flooding and water damage.
More and more California homeowners are investing in standby generators. With all the unpredictable weather and surprise outages, it’s not hard to see why. With a constant supply of electricity, you’ll always be prepared. You can trust our team at Ongaro & Sons to help you choose and install a generator that meets all your needs.
How Does a Whole-House Generator Operate?
Whole house generators sit on a pad outside your Northern California home. They’re sometimes referred to as fixed standby generators.
Whenever there is an outage or your equipment malfunctions, your generator kicks on. It automatically begins powering your home.
When the generator detects a disruption in the current, an automatic transfer switch disconnects from your utility and sends electricity to your panel. Running on your home’s natural gas line, the generator can keep your home powered for days.
When the electric company restores service, your generator will return to standby mode.
Why Your Northern California Home Needs a Standby Generator
Northern California has unique challenges. The power grid can be unpredictable, especially during wildfire season and extreme weather events. A standby generator ensures your home stays powered, safe, and comfortable when the electricity goes out. Here are the top reasons anyone in Northern California should consider installing a standby generator.
Northern California is particularly susceptible to PSPS events, where utility companies intentionally shut off power to prevent wildfires during high-risk weather conditions. A standby generator ensures your home remains powered through these multi-day outages.

How Is a Whole-House Generator Different From a Portable Generator?
Portable generators are excellent for outdoor activities like camping and tailgating. They are designed to power individual items like lights or appliances.
However, they don’t provide nearly as much power as a whole-house generator. Portable generators are also more prone to overheating or energy overload.
Whole-house generators are permanent home fixtures that ensure you’ll never be without power. Even if your home loses power while you’re away, you can be sure your appliances will keep working. Whole-house generators also increase your home value.

Whole-House Generator Maintenance
Your generator backs you up. Do you back your generator up? Preventative maintenance is the best way to avoid generator breakdowns and preserve its lifespan. Since your generator is an asset that increases your home value, it’s a great idea to protect it.
Generators require yearly maintenance from a professional. Just like your car, generators need an oil change to keep the parts running smoothly. Your technician will also need to replace your filter and occasionally change out spark plugs.
Many of the broken generators we repair could have been resolved during a maintenance visit, saving time and money. Schedule maintenance online today for a visit from one of our friendly team members.
