What Maintenance Does a Standby Generator Need in North Texas?
Quick answer
Most manufacturers recommend an annual professional maintenance visit — similar to servicing a central air unit — plus simple monthly and seasonal checks you can do yourself. Staying current on maintenance keeps your warranty valid and, more importantly, keeps the generator ready to actually start when a real outage hits.
Monthly, Seasonal & Annual Maintenance
Monthly (you can do this)
- Confirm the self-test cycle ran and completed without a fault light
- Check that the area around the unit is clear of leaves, debris, and vegetation
- Listen for the self-test to confirm it sounds normal
Seasonal (you can do this)
- Before summer storm season: confirm the unit starts and transfers power correctly
- Before winter: check for any rodent or insect nesting near the enclosure
- After any major storm: inspect for debris or water intrusion around the unit
Annual (call a pro)
- Oil and filter change (for liquid-cooled units)
- Spark plug inspection/replacement
- Battery load test
- Full system test under load
- Transfer switch inspection
- Fuel system and connection check
Warning Signs You Need Service
- Fault light or error code on the control panel
- Unusual noise during the weekly self-test
- Failure to start during a real outage
- Visible corrosion, leaks, or rodent damage
Fault light or error code on the control panel: Something in the self-test or last run detected an issue — don’t wait for an outage to find out what.
Unusual noise during the weekly self-test: Grinding, knocking, or excessive vibration can indicate a mechanical issue.
Failure to start during a real outage: The clearest sign something needs immediate attention before the next event.
Visible corrosion, leaks, or rodent damage: Any of these can affect both performance and safety.
