How backup generators work

Backup generators use advanced technology to keep power flowing to your home in case of a power outage. These systems are stationary, permanently installed devices that resemble an outdoor air conditioning unit. They run on a variety of fuels (natural gas or propane) and connect directly to your home's wiring.

If your home loses power, your generator will automatically kick in, powering parts of your home or even specific appliances based on the settings you have chosen. The generators we offer vary in capacity, from small generators that power a limited number of essential circuits and appliances to generators that can power every circuit in your home for extended periods of time. They shut off on their own when power is restored.

Why you need a backup generator

Power outages can disrupt your life and even be disastrous if you don’t have backup power available. A permanently installed generator can automatically keep your home powered during outages of any length. If you live in an area with frequent storms or outages, or you’ve experienced a devastating outage in the past, installing a generator on your property can help you cope with the effects of power failure by providing automatic power during critical times.

  • Connects to your home’s natural gas line
  • Automatically powers on in the event of an outage
  • Requires minimal yearly maintenance and is sized to fit your home’s needs
  • Installation performed by licensed plumbers and electricians


Power outages can occur for a variety of reasons.
