Generator Maintenance Checklist: Is Your Backup Power Ready for Winter?

Winter in Connecticut is no joke. Snowstorms, freezing temperatures, and extended power outages can disrupt daily life, leaving homeowners and businesses vulnerable. A reliable backup generator ensures you can keep the lights on, stay warm, and maintain essential operations during an outage.

To help you prepare, we’ve created a winter-specific generator maintenance guide focused on portable models. We’ll also explore the benefits of maintenance plans for permanent standby generators to ensure you’re covered no matter your setup.

Winter Maintenance Checklist for Portable Generators

Portable generators are a great solution for temporary power needs, but they require consistent care to operate safely and efficiently. Use this checklist to keep your portable generator ready for any winter storm:

1. Inspect the Generator’s Exterior and Placement

• Check for visible damage: Look for rust, dents, or cracks that could impact the generator’s performance.
• Clear obstructions: Remove snow, ice, and debris from around the generator to maintain proper ventilation.
• Positioning: Ensure the generator is on a stable, level surface and at least 20 feet away from your home to prevent carbon monoxide buildup.

2. Run a Test Cycle

• Run the generator for 15–20 minutes: This helps verify smooth operation and ensures it’s ready to handle a load.
• Listen for unusual noises: Knocking or grinding sounds may indicate mechanical issues that need professional attention.
• Check for odors: Avoid using the generator if you detect strong fuel or burning smells.

3. Maintain the Fuel System

• Inspect fuel levels: Make sure the tank is full before a storm and use a fuel stabilizer to prevent gasoline from degrading.
• Check fuel lines: Look for cracks or leaks and replace them if needed.
• Store fuel safely: Keep extra fuel in an approved container in a cool, dry place.

4. Inspect and Replace Oil

• Check the oil level: Use the dipstick to ensure the oil is topped up.
• Replace oil regularly: If the oil appears dark or hasn’t been changed in over six months, replace it. Always use oil recommended by the manufacturer.

5. Check the Air Filter

• Inspect the filter: Replace it if it’s dirty or clogged to maintain efficient performance.
• Follow manufacturer guidelines: Use only approved filters for your model.

6. Prepare for Post-Storm Maintenance

After a snowstorm, follow these essential steps:

• Clear snow and ice: Use a shovel and ice melt to ensure the generator is free of obstructions.
• Inspect for damage: Check the unit for cracks, dents, or electrical issues caused by ice.
• Run a test cycle: Ensure the generator operates properly before storing it again.

Maintenance Plans for Permanent Standby Generators

While portable generators are a great temporary solution, standby generators provide seamless, automatic power during an outage. They require a different maintenance approach, best handled by professionals.

Why Choose a Maintenance Plan?

Permanent generators are complex machines that integrate directly with your home’s electrical system. Routine professional maintenance ensures safe and reliable operation while extending the life of the generator.
