Essential Maintenance Tips for Your Whole-House Standby Generator

In Part 1, we covered generator costs and installation, and in Part 2, we explored safety guidelines and flood zone considerations. Now, in Part 3, we’ll focus on the maintenance tips needed to keep your generator in top condition, ensuring it's ready when you need it most.

Wondering how to ensure your generator runs smoothly during an emergency? A standby generator is a fully automatic system that kicks in when the grid goes down, offering seamless power to your home. However, like any machine, it requires regular upkeep to function efficiently. Here are the top 5 maintenance tips to keep your generator performing at its best during emergencies:

1. Check the Oil Level Regularly

During extended outages, inspect the oil level every 48 hours. These generators are air- and oil-cooled, meaning they naturally consume oil over time. If the oil level gets too low, the generator will shut off to prevent damage. You’ll need to refill and reset the system, which is especially inconvenient during a storm. Low oil levels can also lead to significant engine wear, so keeping oil within the recommended range is essential to avoid unnecessary breakdowns.

2. Don’t Overfill the Oil

While checking oil levels, be cautious not to overfill. Too much oil can lead to engine shutoff and may cause complete engine failure. Always stick to the manufacturer's recommendations for oil type and amount, and use high-quality synthetic oil for the best performance and longevity of your generator.

3. Change Oil, Filters, and Plugs Regularly

Oil, filters, and wearable parts like spark plugs should be changed according to the manufacturer’s schedule. Keeping up with your generator’s maintenance schedule ensures that vital components are operating efficiently. Regularly changing the oil and filters helps reduce wear and tear, keeping your generator reliable. Always use OEM (Original Equipment Manufacturer) parts and follow manufacturer guidelines to maintain peak performance.

4. Clear Debris and Vegetation

Ensure the area around your generator is free from debris and overgrown vegetation. Blocked airflow can cause the engine to overheat or even create a fire hazard. Proper clearance allows for efficient cooling, preventing potential overheating and helping the generator run smoothly.

5. Schedule Annual Professional Inspections

Even with regular checks, it's important to schedule a professional inspection at least once a year. A technician will examine the generator for wear, leaks, and performance issues, ensuring everything is in peak condition. Annual inspections are especially vital before storm season when power outages are more likely, giving you the peace of mind that your generator is ready when you need it.

From Our Experience:

Common Generator Issues

At Arieli Custom Homes, we’ve seen that most generator problems arise from poor oil maintenance—low oil levels, overfilling, or oil consumption issues. While these are preventable with proper care, emergencies can make mistakes more likely.

For instance, during a recent storm, the parents of one of our clients ran out of oil, causing their generator to shut off. In an attempt to quickly get it running again, they accidentally overfilled the oil. This led to oil being blown into the airbox, clogging the air filter and causing the generator to shut down repeatedly with a “low voltage” error.

Our team stepped in to resolve the issue, draining the oil to the correct level, cleaning the airbox, and replacing the air filter. The generator was up and running again in no time, but the situation highlights how critical proper oil management is, especially during emergencies.

By following the tips outlined above and scheduling regular professional inspections, you can avoid similar scenarios and ensure your generator works reliably when you need it most.
