How Often Should You Clean Your Dryer Vent?

Dryer vent cleaning is one of those home maintenance jobs that's easy to forget — until the dryer stops drying well, or worse. Here's how often it should be done, the warning signs, and why it matters more than most people realize.

Why it matters: it's a safety issue, not just performance

Every load of laundry sheds lint. Some of it escapes the lint trap and builds up inside the vent duct. Lint is highly flammable, and a clogged vent traps heat — which is why clogged dryer vents are a well-documented cause of house fires. Cleaning the vent restores airflow and removes that risk.

How often should you clean your dryer vent?

For most homes, about once a year is the right cadence. Clean more often if:

• You do a lot of laundry (large family, pets, bedding).
• Your dryer and vent run a long distance to the outside.
• You've noticed any of the warning signs below.

Warning signs your vent is clogged

• Clothes take two cycles to dry, or come out still damp.
• The dryer or laundry room feels unusually hot during a cycle.
• There's a burning or musty smell when the dryer runs.
• The outside vent flap barely opens, or little air comes out.
• Lint collects around the lint trap faster than usual.

DIY vs hiring a pro

You can vacuum the lint trap housing and the visible part of the duct yourself. A full cleaning — pulling the dryer, clearing the whole run to the exterior vent, and checking airflow — is faster and more thorough with the right brushes and a vacuum. It also catches problems like crushed or disconnected ducts.
