How Often Should You Service Your Generac Standby Generator?

April 17, 2026

A standby generator is one of the most reliable ways to keep your home powered during unexpected outages—but like any mechanical system, it needs routine care to perform when it matters most. If you’ve invested in a Generac standby generator, regular generator servicing isn’t optional—it’s essential. At Premier Plus Electric, we help homeowners protect that investment with professional maintenance designed to keep systems running safely and efficiently year-round.

So, how often should you service your generator? In general, most manufacturers recommend at least one full professional service per year. However, usage, environmental conditions, and fuel type can all influence how often maintenance is needed. For homes in areas prone to frequent outages or severe weather, more frequent inspections—such as every 6 months—may be a smart move.

Routine servicing typically includes a comprehensive system check to ensure everything is operating properly. This means inspecting and replacing the oil and filters, checking the battery, testing the automatic transfer switch, and confirming that the unit starts and runs smoothly under load. These steps are critical because standby generators often sit idle for long periods, and small issues can go unnoticed until the power goes out—when you need the system most.

Another key factor is runtime. If your Generac generator has been used extensively during a long outage, it may require service sooner than the standard annual schedule. Many systems are programmed to run weekly or biweekly self-tests, which help maintain readiness, but these tests don’t replace a full inspection by a trained technician.

Neglecting maintenance can lead to reduced efficiency, unexpected breakdowns, and even costly repairs. Issues like stale fuel, worn spark plugs, or a weak battery can prevent your generator from starting altogether. Regular servicing not only improves reliability but also extends the lifespan of your equipment and ensures it meets safety standards.

At Premier Plus Electric, we make generator maintenance simple and stress-free. Our experienced team understands the ins and outs of Generac systems and provides thorough inspections, timely tune-ups, and expert recommendations tailored to your home’s needs. Whether your generator is brand new or has been protecting your home for years, staying on top of service is the best way to ensure it’s always ready.
