How to Winterize Your Generator? | Paramount Power Systems

Power outages can be quite frustrating, especially when the temperatures are below freezing. When the power goes out, it can leave you in the dark and cold for days. Whether a snow storm or a blizzard has knocked out your electricity, a generator can keep you powered up in the meantime. To stay safe and warm in winter, long-term power is necessary.

The winter can be especially harsh on your generator, as they are located outside. But if your generator is not ready for the winter months, you’ll be putting yourself and your family at risk.

Below are some tips to help you prepare your generator for winter. Keep on reading to learn more.


Most generators tend to struggle in temperatures below 0° C. The engine and its components may get too cold, and the fuel inside won’t be able to vaporize properly.

While the oil won’t freeze in colder weather, it will thicken. The battery inside the generator may also freeze up and die. If you find your generator not starting in cold weather, that’s why.

On top of that, if you own a generator, you should also consider exposure to ice and snow a risk. Moisture can be a death sentence to your unit, and any ice or snow will eventually melt.


Whether you are using a home backup or portable generator, the same general safety guidelines apply. Keep it somewhere dry and take proper precautions for protecting your generator from the elements.

A transfer switch is needed for the generator to supply power to your house.

The two most important things to do to winterize a generator in areas where it gets very cold and the temperature falls below freezing is to ensure your generator has a cold weather kit installed. These accessories may include a carburetor heater, fuel regulator heater, a battery warmer or block heater depending on the size of the generator. Equally important, ensure you get regular maintenance done every year including the oil and filters changed.

Consult with your local generator supplier in Toronto about the tools and devices necessary for keeping your generator running smoothly in winter.


The cold and excess moisture can wreak havoc on a generator’s performance. Although winter isn’t known for rainy conditions, snow and ice could still affect your unit’s performance. When it comes to winterizing your generator, you need to ensure that it is protected from the harsh winter elements. The generator comes with a cover which will keep it protected from any moisture entering while allowing sufficient airflow around it.

Place your generator on a flat surface that won’t collect water. We recommend a concrete pad or base so that if the ground shifts, the generator will stay level on the pad. The last thing you want to do is search for a new generator during a Toronto winter.


As with all things in life, preparation is key. Generators are no different. You need to get yours ready for winter as soon as possible if you want it to last the entire season. Once the cold and snow start coming down harder, you probably wouldn’t want to go outside to do anything, but that means your generator will require even more attention to keep it running smoothly.
