Why Dryer Vent Cleaning Should Be Done Every Year

Why Dryer Vent Cleaning Should Be Done Every Year

Dryer vent cleaning might not be top of mind for most renters or landlords, but it should be. It’s a quick task that can make a big difference in terms of safety, energy efficiency, and appliance lifespan.

Here’s why we recommend having your dryer vent professionally cleaned at least once a year:

1. Reduces the Risk of Fire

This is the biggest reason. Lint is highly flammable, and over time it can build up in the dryer vent hose and the wall duct leading outside. According to the U.S. Fire Administration, dryer fires cause thousands of residential fires each year—most due to failure to clean the vents.

Annual cleaning helps prevent this risk and keeps your home safer.

2. Improves Dryer Performance

If your dryer isn’t venting properly, it has to work harder to dry clothes. That can lead to:

Longer drying times
Damp or musty laundry
Higher energy bills

A clean vent allows air to flow freely and helps your dryer work as it should.

3. Extends the Life of the Appliance

When a dryer has to overwork due to a blocked vent, the motor and other components can wear out faster. Keeping the vent clean helps protect your investment by reducing unnecessary strain on the machine.

4. Prevents Moisture and Mold Issues

Blocked vents can cause warm, moist air to back up into the laundry area. Over time, this can lead to:

Excess humidity
Mold or mildew growth
Wall or ceiling damage

A clear, properly vented exhaust helps avoid these issues.

5. Required for Property Compliance

For many rental properties, annual dryer vent cleaning is part of basic fire safety protocol. If you’re a tenant, this may be included in your lease or handled by your property management team.

When in doubt, ask—and don’t skip it.
