What's Included in Generator Maintenance:
Why Generator Maintenance Matters
Your generator is a mechanical system that sits idle for months at a time, then needs to perform flawlessly during an emergency. Without regular maintenance, fuel degrades, oil breaks down, batteries lose charge, and small problems compound into major failures. Here's why routine generator maintenance is essential:
Prevent Costly Breakdowns
Catching issues early prevents expensive emergency repairs and extends your generator's life by years.
Ensure Reliable Startup
A maintained generator starts on the first try during an outage — when every second counts.
Protect Your Warranty
Most manufacturer warranties require documented annual service to remain valid.
Lower Lifetime Costs
Preventative maintenance costs a fraction of emergency repairs or premature replacement.
Peak Fuel Efficiency
A tuned generator runs more efficiently, saving fuel and reducing operating costs.
True Peace of Mind
Sleep soundly knowing your generator is ready for the next storm or grid failure.
Manufacturer-Recommended Service Schedules
Every generator manufacturer publishes a recommended maintenance schedule based on operating hours and time intervals. Following these schedules is critical for warranty compliance and optimal performance. Here are the standard maintenance intervals for the most popular generator brands:
| Service Item | Generac | Kohler | Briggs & Stratton |
|---|---|---|---|
| Oil & Filter Change | 200 hrs / 1 year | 150 hrs / 1 year | 200 hrs / 1 year |
| Spark Plugs | 400 hrs / 2 years | 300 hrs / 2 years | 400 hrs / 2 years |
| Air Filter | 200 hrs / 1 year | 200 hrs / 1 year | 200 hrs / 1 year |
| Battery | 2 years | 2–3 years | 2 years |
| Coolant Service | 2 years | 2 years | 2 years |
| Valve Adjustment | 400 hrs / 2 years | 300 hrs / 2 years | 400 hrs / 2 years |
| Full Inspection | Every service | Every service | Every service |
*Always consult your owner's manual for the exact maintenance schedule for your specific model. Our technicians follow manufacturer specifications precisely.
Signs Your Generator Needs Maintenance
Don't wait for your generator to fail during an outage. Watch for these warning signs that indicate your generator needs professional maintenance:
Failed Weekly Exercise
Your generator should run its weekly exercise cycle automatically. If it fails, service is needed immediately.
Warning Lights or Alarms
Any fault codes, check engine lights, or alarm indicators require immediate professional attention.
Unusual Noises
Knocking, rattling, or rough running during exercise cycles indicates internal wear or mechanical issues.
Oil Discoloration
Dark, dirty, or low oil levels indicate the oil needs changing — a critical maintenance item.
Weak or Dead Battery
If your generator struggles to start or the battery tests weak, replacement is needed before the next outage.
Overdue for Service
If it has been more than 12 months or 200 hours since your last service, schedule maintenance now.
What Happens During a Maintenance Visit
Our comprehensive generator maintenance visits follow a detailed 16-point inspection checklist. Here's exactly what our technicians do during every service appointment:
Visual Inspection
Technician examines the generator enclosure, fuel lines, exhaust system, and surrounding area for damage, leaks, or debris.
Oil & Filter Service
Drain old oil, replace the oil filter, and refill with manufacturer-specified oil grade and quantity.
Spark Plug Service
Remove, inspect, and clean or replace spark plugs. Check gap settings and torque to specification.
Air Filter Service
Inspect air filter for contamination. Clean reusable filters or replace disposable filters.
Battery Testing
Load test the battery, check terminals for corrosion, clean connections, and replace if voltage is low.
Coolant Check
Inspect coolant level, check for leaks in the cooling system, and top off or replace as needed.
Fuel System Inspection
Check fuel lines, connections, and filters for leaks or blockages. Test fuel pressure and regulator function.
Transfer Switch Test
Manually test the automatic transfer switch to ensure proper operation during power outages.
Control Panel Diagnostics
Run full diagnostic scan, check for error codes, verify settings, and update firmware if available.
Load Bank Test
Apply a controlled electrical load to verify the generator can handle your home's power demands.
Voltage & Frequency Check
Verify output voltage and frequency are within manufacturer specifications under load.
Exercise Schedule Verification
Confirm the generator's automatic exercise cycle is properly configured and functioning.
Final Report
Technician provides a detailed service report with findings, recommendations, and next service date.
DIY vs. Professional Generator Maintenance
Some homeowners wonder if they can maintain their own generator. While basic tasks like checking oil levels and clearing debris are safe to handle, professional maintenance is strongly recommended for several important reasons:
DIY Maintenance
- Check oil level
- Clear debris from enclosure
- Test battery voltage
- Run manual exercise cycle
- Visual inspection
Safe for homeowners, but limited scope.
Professional Maintenance
- Full 16-point inspection
- Oil & filter change
- Spark plug service
- Load bank testing
- Transfer switch test
- Diagnostic scan
- Firmware updates
- Warranty documentation
Required for warranty compliance. Comprehensive and safe.
