Frequently Asked Questions

What is an automatic standby generator?
An automatic standby generator is a back-up electrical system that operates whether you are at home or away. It automatically supplies power to essential circuits of your home within seconds of a utility outage. After utility power returns, the generator shuts itself off and awaits the next outage. It operates on natural gas or liquid propane and sits outside just like a central air conditioning unit.

What will it power?
GUARDIAN® generators supply electricity to the electrical panel circuits of your home through a built-in load center. You select the number of circuits you want to protect and match it to the appropriate generator system. Everything on that circuit will be protected. GUARDIAN also powers furnaces, air conditioners, well pumps, water heaters and other appliances that are hard wired into your electrical panel.

Why should I buy an automatic standby generator instead of a portable generator?
While portable generators do supply power, an automatic standby generator produces a higher quality of electricity. It operates automatically and runs a weekly self-test to ensure proper response to your needs. There are no extension cords to plug in and no gas tanks to fill. It operates automatically so it protects your home even when you’re away. When utility power returns, the standby generator shuts itself off.

Do they have to be maintained?
Just like your car’s engine, generators need periodic oil and filter changes. Many customers rely on GUARDIAN’s preventative maintenance kits to satisfy routine maintenance requirements. Refer to your owner's manual for routine maintenance procedures and schedules. Kits can be purchased through the business that sold you your GUARDIAN generator.

How long does it take to install an automatic standby generator?
GUARDIAN air-cooled models, which come equipped with a comprehensive installation manual, can take as little as four hours to install. They come pre-mounted on a composite pad to further simplify installation. Liquid-cooled generators normally require up to 14 hours to install. Because of their additional weight, liquid-cooled units must be installed on a stronger mounting surface such as a concrete slab.

What is the cost of a service/maintenance contract?
Costs are determined by the installing dealer and are based upon service levels. Cost will also vary based on hourly labor rates in your local area.
