A Generac generator is an essential investment for homeowners and businesses looking to ensure reliable backup power during outages. Like any high-quality equipment, routine maintenance is critical for optimal performance and longevity. At Premier Plus Electric, Inc., we specialize in professional Generac generator service and repair, and we often get asked: “How often should I service my generator?”
In this article, we’ll cover expert recommendations, common maintenance schedules, and why regular servicing is key to keeping your generator ready when you need it most.
Even the most durable generators require care to prevent breakdowns, costly repairs, and reduced efficiency. Regular maintenance ensures reliable performance during power outages, extends the lifespan of your generator, helps maintain warranty compliance, and reduces the risk of unexpected failures. Generators work hard, especially during storms, high-demand periods, or extreme weather. Skipping maintenance can lead to fuel issues, battery failure, or damaged components, leaving your home or business without power when it matters most.
Every six months or after 100 hours of operation, whichever comes first, is the recommended schedule for checking key components and performing routine maintenance. This schedule is ideal for home standby generators and ensures your system stays in top condition. During this maintenance, the engine oil should be checked and changed as needed, air and fuel filters replaced, the battery and connections inspected, and system performance tested.
Even if you perform basic maintenance yourself, it is essential to schedule a professional service once a year. A certified technician from Premier Plus Electric, Inc. will inspect and clean the generator thoroughly, test voltage output and transfer switches, identify potential issues before they become costly repairs, and ensure your generator meets Generac’s recommended standards.
Certain times of the year, like summer and winter, can put extra stress on generators. Regular seasonal inspections help prevent battery degradation in cold weather, ensure proper cooling and airflow during hot months, and test fuel systems to prevent clogs and corrosion. Seasonal check-ups also give you peace of mind that your generator is ready for storm season or extreme temperature events.
Running your generator monthly helps maintain battery charge and engine performance. Always use fresh, high-quality fuel to prevent clogs and fuel system issues. Keep the surrounding area clear of debris, vegetation, and moisture to protect your generator’s components. Regularly check for unusual noises, smoke, or smells, and address any issues immediately with professional service. Following these practices ensures your Generac generator will perform reliably whenever you need it.
