Generator Maintenance Tips to Keep the Power On All Winter

When West Virginia winter storms hit, power outages can happen in an instant, leaving your home cold, dark, and uncomfortable. A well-maintained generator is your first line of defense against unexpected blackouts, keeping your heat, lights, and essential systems running no matter what the weather brings. With a few preventive maintenance steps, you can ensure your generator is ready to perform when you need it most.

Check and Replace Oil and Filters

Oil and filters are the lifeblood of your generator’s engine. Over time, oil becomes thick with debris and loses its ability to lubricate moving parts effectively, while clogged filters can restrict airflow and fuel delivery. Regular oil changes prevent friction damage and extend your generator’s lifespan.

Before winter sets in, inspect the oil level and top it off if needed. Most manufacturers recommend changing the oil every 50 – 100 hours of use or at least once per season. Replace both the oil and air filters during this time to keep the engine breathing freely and running efficiently. Taking care of these simple tasks now can prevent costly repairs later and ensure smooth operation when power failures strike.

Inspect Fuel and Battery Systems

Nothing is worse than finding out your generator won’t start during a storm. Two of the most common causes are bad fuel and weak batteries. For fuel-powered generators, check for stale or contaminated gasoline and replace it with fresh fuel before winter. If you use a diesel or propane model, inspect hoses and connections for leaks or cracks that could restrict flow.

For battery-powered or electric-start systems, test the battery’s charge and clean any corrosion from the terminals. A quick check every few weeks helps you avoid cold-weather starting issues that could leave you without backup power when you need it most.

Test Run Your Generator Monthly

Running your generator for 15 – 20 minutes each month keeps internal components lubricated and prevents fuel from going stale. This simple step also gives you the chance to confirm that your system starts easily and transitions smoothly into operation.

During each test, check for any unusual noises, smoke, or vibration, which can indicate mechanical or electrical issues. It’s also a good time to verify that your transfer switch (if you have one) functions correctly. By catching small issues during a test run, you can fix them before they become major problems during an outage.

Schedule a Professional Generator Tune-Up

While basic maintenance can be done at home, nothing replaces a professional inspection. A certified technician from Al Marino can perform a complete tune-up, checking your generator’s voltage output, fuel system, and control panel to ensure it’s fully prepared for winter.

If it’s been more than a year since your last service, now is the perfect time to schedule maintenance.
