Maintaining Your Standby Generator Year-Round

A backup generator is only valuable if it works when the power goes out. Regular maintenance keeps it reliable and protects your investment—especially through Central Texas heat, storms, and hard freezes.

1. Run a Monthly Exercise Cycle

Most manufacturers recommend running the generator for 15–20 minutes once a month. This keeps internal parts lubricated, charges the battery, and alerts you to issues before an emergency.

2. Check Fuel and Connections

• Natural Gas/Propane: Make sure valves are open and lines are free of leaks or corrosion.

• Diesel or Gasoline: Keep fuel fresh and stabilized; replace old fuel after 12 months.

3. Inspect Air Filters and Oil

Change filters and oil according to the manufacturer’s schedule—or at least once a year. Dirty filters and old oil reduce efficiency and can trigger shutdowns during a storm or freeze.

4. Keep the Area Clear

Maintain three feet of clearance around the unit. Remove leaves, ice, or snow that could block airflow or create a fire hazard.

5. Schedule Annual Load Testing

A professional load test ensures the generator can handle its rated output under real conditions. It’s the best way to confirm your system will perform during a grid failure.

Routine care extends equipment life, maintains warranty coverage, and gives you peace of mind when the next hard freeze hits.
