Your dryer works hard every week — but when was the last time you thought about the vent behind it? A clogged dryer vent is one of the most common — and most dangerous — hidden problems in a home. Here are the five warning signs:

1. Clothes take forever to dry

If a normal load needs two cycles, the hot, moist air has nowhere to go. Lint buildup narrows the vent line until your dryer is working twice as hard for half the result.

2. The dryer — or the laundry room — feels unusually hot

Heat with nowhere to escape builds up in the dryer and the room around it. If the top of your dryer is hot to the touch, that’s a red flag.

3. You smell something burning

Lint is extremely flammable. A burning smell during or after a cycle can mean lint is overheating inside the vent — stop using the dryer and call a professional.

4. There’s lint where it shouldn’t be

Lint around the dryer door, on your clothes, or caked around the outside vent cover means the line is backing up instead of pushing air out.

5. It’s been more than a year

Even without obvious symptoms, a dryer vent should be professionally cleaned at least once a year — and with winter laundry season coming, now is the time.

Why it matters

According to the U.S. Fire Administration, thousands of home fires every year start with clothes dryers — and lint buildup is the leading cause. Beyond safety, a clogged vent wastes energy and can cut years off your dryer’s life.
