How to Winterize Your Generator Before the First Snow in Erie, PA

Winters in NW Pennsylvania are no joke. In Erie, the first snow often arrives early—and heavy lake-effect storms can leave neighborhoods without power for hours or even days. That’s why having a standby or portable generator ready to go isn’t just a convenience; it’s peace of mind. But to make sure your generator works when you need it most, it’s important to winterize it before the first snow hits.

At Electrical & Mechanical Systems, we help homeowners and small businesses across Erie County stay prepared. Here’s your step-by-step guide to winterizing your generator this season.

1. Check the Battery and Charging System

Cold weather is hard on batteries. If your generator won’t crank, it won’t help you in a storm.

• Inspect the battery terminals for corrosion.

• Test the voltage and replace the battery if it’s weak.

• Make sure any trickle chargers or built-in battery heaters are working properly.

2. Change the Oil and Filters

Engines need clean oil to run efficiently, and cold weather thickens old oil.

• Use the manufacturer’s recommended winter-weight oil (often 5W-30 synthetic).

• Replace oil and air filters so the engine can breathe and lubricate properly.

• Keep an extra set on hand in case of extended outages.

3. Inspect Cold-Weather Kits

Many standby generators are equipped with cold-weather kits that include battery warmers, oil heaters, or block heaters.

• Confirm these are plugged in and operational.

• If your unit doesn’t have one, consider an upgrade—Erie winters justify it.

4. Top Off Your Fuel Supply

• Natural Gas Units: Call your gas provider to confirm line pressure is adequate during peak demand.

• Propane Units: Make sure your tank is at least 70–80% full going into storm season. Snowstorms can delay deliveries.

• Diesel Units: Fill the tank and add a winter fuel stabilizer to prevent gelling in low temps.

5. Clear the Surrounding Area

Snow and ice buildup around your generator can block airflow and create hazards.

• Keep at least 3–5 feet of clearance around the enclosure.

• Shovel paths to the unit and the propane tank, if applicable.

• Remove leaves and debris before the first snow falls.

6. Run a Test Cycle

Nothing beats a real-world test:

• Switch the generator to “Auto” mode and simulate a power outage.

• Let it run under load for 15–20 minutes.

• Listen for unusual noises and check for leaks.

7. Safety First

• Never operate a portable generator indoors or in a garage.

• Make sure you have working carbon monoxide detectors in your home.

• For standby units, ensure the transfer switch is tested and operating correctly.
