The One Spot You Forgot to Shovel and Why It Could Be Deadly

When snow piles up, most people focus on driveways, sidewalks, steps, and front walkways. But there is one important spot many homeowners forget to clear: the area around exterior vents. Blocked furnace, dryer, water heater, or fireplace vents can create serious safety risks, including carbon monoxide buildup and fire hazards.

Why Exterior Vents Matter

Many modern heating systems and appliances vent through side walls rather than chimneys. These vents allow exhaust gases to leave your home safely and help appliances operate properly. When snow drifts block them, dangerous gases can back up into the house.

Carbon monoxide is especially dangerous because it is colorless and odorless. Exposure can cause headaches, dizziness, nausea, confusion, and in severe cases, death.

Which Vents Should You Check?

After a snowstorm, walk around your home and look for exterior vents. Common vents include furnace exhaust pipes, water heater vents, dryer vents, fireplace vents, and fresh-air intake pipes. They may be located low on the side of the house, where drifting snow can cover them quickly.

How to Clear Vents Safely

Use a broom, gloved hand, or small plastic shovel to gently clear snow from around vents. Avoid hitting pipes or covers with metal tools, which can damage them. Make sure there is enough space around the vent for air to flow freely.

Do not forget to check again if wind causes drifting snow after you have already shoveled. A vent can become blocked even after the storm ends.

Do Not Ignore Dryer Vents

A blocked dryer vent can prevent moisture and lint from escaping properly. This may cause longer drying times, overheating, or even a fire risk. If your dryer seems unusually hot or clothes are taking too long to dry after a storm, inspect the exterior vent.

Install Carbon Monoxide Detectors

Every home with fuel-burning appliances should have working carbon monoxide detectors. Place them according to manufacturer instructions and test them regularly. Replace batteries as needed and pay attention to expiration dates.

Final Thoughts

The spot you forgot to shovel could be one of the most important areas around your home. Keeping exterior vents clear of snow helps prevent carbon monoxide buildup, appliance problems, and fire risks. After every major snowfall, add vent checks to your winter safety routine.
