What Maintenance Does a Standby Generator Need in North Texas?
Quick answer
Follow your specific generator model's maintenance schedule — manufacturers set intervals by both calendar time and operating hours, so a generator that's run frequently during outages may need service sooner than a once-a-year visit covers. Most manufacturers do call for at least one professional visit annually, plus simple monthly and seasonal checks you can do yourself. Keep service records and check your model's actual warranty terms, since requirements vary by manufacturer — staying current matters most for keeping the generator ready to actually start when a real outage hits.
Routine Checks & Professional 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 storm season: confirm that the scheduled self-test cycle has been completing without a fault indicator. Transfer-under-load testing is a technician task; confirm its timing and scope for your model.
- 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
Professional maintenance — follow your model's schedule
- Oil and filter changes for both air-cooled and liquid-cooled models, per your generator's maintenance schedule
- Spark plug inspection/replacement
- Battery load test
- Full system test under load
- Transfer switch inspection
- Fuel system and connection check
This is a general schedule, not a substitute for your specific model's requirements. Manufacturers set maintenance around both calendar time and total run hours — a generator that has run frequently during outages or extended power use may need service sooner than once a year. Check your owner's manual or ask us to confirm the interval for your exact model.
Warning Signs You Need Service
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.
