Missouri winters can bring sudden power outages from ice, snow, and high winds. For homes and businesses in St. Louis County and St. Charles County, a well-maintained backup generator provides peace of mind and uninterrupted operation when it matters most. Regular inspections and testing keep your system dependable through every storm.

Test Regularly Under Load

Running your generator monthly helps keep all moving parts lubricated and verifies that automatic startup systems function correctly. Always test under load—this simulates real conditions and confirms your generator can handle the power demands of your building.

Replace Fluids and Filters

Cold weather thickens oil and can cause old fuel to degrade. Replace fuel and oil according to manufacturer recommendations, and always keep fresh supplies on hand. Dirty filters reduce efficiency and can prevent engines from starting when temperatures drop.

Inspect Batteries and Electrical Components

Generator batteries are especially vulnerable to the cold. Corroded terminals, weak voltage, or loose connections can all result in a failure to start. Use a multimeter to verify charge levels and keep spare batteries available during storm season.

Check Ventilation and Placement

Ensure your generator’s exhaust area is free from snow or debris. Blocked vents can lead to overheating or carbon monoxide buildup. Proper airflow keeps both you and your equipment safe.

Schedule Professional Maintenance

Even if you regularly test your generator, professional maintenance is critical. AMF Electric technicians inspect wiring, voltage regulation, transfer switch performance, and grounding integrity. They’ll ensure your system meets all local codes and operates safely.

Create a Winter Preparedness Checklist

Include generator startup procedures, fuel supply checks, and maintenance logs. This ensures consistency across your team or household and reduces confusion during an emergency.

Conclusion

Don’t wait until a storm leaves you in the dark. Reliable backup power starts with preparation. AMF Electric provides comprehensive generator inspections, testing, and maintenance services to keep your systems performing when you need them most—so your property stays powered and protected through every Missouri winter.
