5 Ways to Prepare Your Generator for Fall and Winter

As the days get shorter and the nights get cooler, fall is the perfect time to ensure your home is ready for anything Mother Nature throws your way—especially when it comes to power outages. Whether you're dealing with surprise autumn storms or preparing for deep winter freezes, having your generator ready is one of the smartest things you can do.

At Sparks Generators, we specialize in backup power solutions to keep your home safe and comfortable all year round. Here are 5 key ways to prepare your generator for the colder seasons ahead, including some tips specifically for Generac generators—one of the most trusted names in the business.

1. Schedule a Full Generator Inspection

Just like your furnace or HVAC system, your generator needs regular maintenance to perform reliably—especially before heavy seasonal use. A professional inspection will include:

• Checking oil and coolant levels

• Inspecting and cleaning air filters

• Testing battery voltage

• Running a full diagnostic

• Verifying startup and load transfer function

For Generac owners, make sure your Mobile Link™ remote monitoring is connected and working properly. This allows you (and us!) to monitor your generator status in real-time.

2. Test Run Your Generator

Even if your generator hasn’t seen much action over the summer, you’ll want to give it a test run. Run it under load to ensure everything’s operating correctly, including:

• Transfer switch operation

• Output power levels

• Overall noise and performance

Listen for unusual sounds and monitor for warning lights or error codes. Generac generators are designed for self-testing, but a hands-on test helps give you peace of mind.

3. Stock Up on Fuel and Keep It Fresh

For portable generators, make sure you have a safe supply of fresh gasoline or propane. Gasoline can degrade over time, especially in cooler weather, so consider using a fuel stabilizer if you’re storing it long term.

If you have a standby Generac generator connected to a natural gas or propane line, double-check that the fuel supply is ready and lines are inspected for leaks or pressure issues.

4. Clear the Area Around Your Generator

Leaves, snow, and debris can obstruct your generator’s ventilation and create fire hazards. Be sure to:

• Trim back bushes and trees

• Remove leaves and clutter

• Ensure the exhaust is not blocked

• Maintain a 3–5 ft clearance around the unit

This is especially important for air-cooled Generac generators, which rely on proper airflow to prevent overheating.

5. Upgrade or Add Cold Weather Accessories

Generators need a little extra care in the winter, and Generac makes it easy with accessories designed for colder climates:

• Cold Weather Kits: Includes battery warmers and oil heaters for optimal startup

• Extreme Cold Weather Kits: For climates regularly below 0°F

• Heater Kits for Liquid-Cooled Models

• Remote Monitoring for convenient system checks from your phone

Ask Sparks Generators about upgrading your existing unit or getting a new generator with cold-weather readiness built-in.
