Owning a generator is one of the smartest ways to ensure your home or business stays powered during outages. But like any mechanical system, generators require upkeep. Without regular generator maintenance, even the best unit can break down when you need it most—leading to expensive repairs or even full replacements. In this blog, we’ll walk you through why generator maintenance matters, what it involves, and how often it should be done to keep your investment in top shape.
Why Generator Maintenance Should Never Be Skipped
A generator’s job is simple: kick in when your main power goes out. But internally, it’s a complex engine system that needs care to stay reliable. Skipping maintenance can lead to clogged filters, degraded oil, fuel system issues, or worse—total failure during an emergency.
When routine generator maintenance is done correctly, it increases the lifespan of your unit, ensures consistent performance, and prevents minor problems from becoming major ones. More importantly, it gives you peace of mind knowing your backup power is ready to perform at a moment’s notice.
Key Generator Maintenance Tasks
1. Oil and Filter Changes
Just like your car, generators need regular oil changes to function smoothly. Dirty or old oil leads to engine wear, overheating, and breakdowns. Most manufacturers recommend changing the oil every 100 to 200 hours of use or at least once per year. Always replace the oil filter at the same time to ensure proper filtration.
2. Air Filter Replacement
A clogged air filter can choke your generator’s performance. Replace it every 200-300 hours or more often if you operate the unit in dusty environments. Clean airflow helps your generator run more efficiently and protects internal components.
3. Battery Inspection
If your generator uses a battery for electric start, regular testing is essential. A dead battery means the generator won’t start when you need it. Check for corrosion, clean terminals, and make sure it’s holding a charge.
4. Fuel System Check
Fuel quality degrades over time, especially if the generator runs on gasoline. Generator maintenance should include checking for stale fuel, water contamination, and inspecting fuel lines for cracks or leaks. If your unit uses propane or diesel, verify all connections are tight and free from damage.
5. Run It Monthly
Running your generator for 15-30 minutes every month helps keep fluids circulating and battery charged. This “exercise” also ensures you’ll notice any irregularities before a real emergency hits.
6. Spark Plug and Wiring Check
Worn spark plugs can lead to hard starts or misfires. Inspect and replace them according to the manual. While you’re at it, check for frayed wires, loose connections, or rodent damage—especially if the generator is stored outdoors or in a shed.
How Often Should You Perform Generator Maintenance?
Routine maintenance frequency depends on how often your generator runs. Here’s a general guide:
- Standby Generators (used occasionally): Basic inspection every 3 months, full maintenance annually
- Portable Generators (used for projects or outages): Check before and after each use
- Heavy-Use Units (daily or weekly): Monthly maintenance and oil changes every 100 hours
Always refer to your manufacturer’s manual for exact intervals and specs. If you’re unsure, the team at Northside Power can help build a maintenance schedule tailored to your unit and usage.
DIY vs. Professional Generator Maintenance
While many generator maintenance tasks can be handled by owners, there are times when professional servicing is the better choice—especially for standby or commercial-grade units.
Professional technicians use specialized tools and diagnostic software to check engine performance, test load capabilities, and update firmware on modern models. They can also spot early signs of trouble that might be missed during a basic inspection.
At Northside Power, we offer routine maintenance plans designed to keep your generator running at peak performance, without the hassle of remembering when things are due.
Extend Your Generator’s Life with These Pro Tips
- Keep it Covered: Use a weather-resistant cover or build a ventilated enclosure to shield it from rain, snow, and debris
- Use Fuel Stabilizer: Add stabilizer to fuel tanks if the generator won’t be used for more than 30 days
- Label Service Dates: Keep a simple log of oil changes, filter replacements, and inspections
- Keep Extra Parts On-Hand: Have spare oil, filters, and spark plugs readily available for quick fixes
