What do I need to do during a power outage?
Relax. Natural gas standby generators start automatically within seconds of sensing a power outage. Once electric power is restored, the generator shuts down allowing service to flow from the electric utility. And just to make sure they work when you need them, natural gas generators automatically test themselves each week. For more information, view Generac’s how-to video now. To ensure that your generator can support you during an extended power outage, ask your generator dealer to run a full load test for a minimum of one hour following final installation.

What is the difference between an automatic air-cooled generator and an automatic liquid-cooled generator?
The engines! Air-cooled generators come with engines that use fans to force air across the engine for cooling, while liquid-cooled generators use enclosed radiator systems for cooling, similar to an automobile. Generally, liquid-cooled engines are used on larger kW generators due to the larger engines required for the higher power output.

How long can I expect an automatic standby generator to last?
With typical usage and proper maintenance, an automatic standby generator will operate 1,500 to 3,000 hours providing years of reliable service.

Do they have to be maintained?
Yes, simple maintenance is required. All generators require periodic oil and filter changes to ensure maximum performance for years of reliable service. Preventative maintenance kits are available and many participating dealers offer annual maintenance contracts for a worry-free ownership experience. Refer to the owner’s manual for routine maintenance procedures and schedules.
