Generator Maintenance Solutions
How often should you schedule maintenance for a standby generator? The general rule is to schedule service at least once every year or two. That’s true even if you didn’t run the generator during that time, since many generator warranties require it as a condition of coverage. Your home insurance may also require it if you get a premium discount due to the generator. Issues can also occur even without the generator turning on.
The other consideration is maintenance based on hours of usage. This is what’s going to minimize your short-term operating costs and your total cost of ownership. Typically, a generator requires a service appointment every 200 hours. That said, check the owner’s manual for the manufacturer’s recommendation for your specific model. If you experience multiple extended outages, you may have to schedule annually or even several times a year.
Homeowners should perform basic maintenance themselves. That includes checking the generator at least once a month, even when it goes unused. Clean the generator area to ensure that it’s free of clutter and other hazards. Look for any signs of wear or damage that may require professional attention. Note also that many modern generators will indicate the maintenance interval via a light on the control panel. If you see the light active, you should schedule maintenance regardless of how long it’s been.
During the service appointment, an electrician will perform a multipoint inspection. That will encompass the generator itself, the fuel system and lines, and electrical panel, including the transfer switch. An electrician will clean all the equipment during this process. A battery inspection and testing are also key aspects of this service. The electrician will change the oil if needed too. If there’s any wear beyond normal usage, your electrician may recommend one or more proactive repairs.
