A clogged dryer vent is a fire hazard hiding in plain sight. Your dryer usually gives you clear warning signs before it becomes dangerous — here are six to watch for.
1. Clothes take more than one cycle to dry
The most common sign. When lint blocks the vent, hot, moist air cannot escape, so clothes come out damp and need a second or third cycle.
2. The dryer and laundry are very hot
If the dryer, the clothes, or the laundry room feel unusually hot, trapped heat is building up — a sign the vent is not exhausting properly.
3. A burning or hot-lint smell
A hot, dusty, or burning smell while the dryer runs means lint is overheating. Stop using the dryer and have the vent cleaned promptly.
4. Lint or debris around the outside vent
Check the exterior vent hood. Lint around it, or a flap that will not open, means the line is packed and airflow is restricted.
5. More lint than usual on the screen
Excess lint on the screen, or a musty, humid feeling in the laundry room, can indicate the vent is not carrying moisture and lint away.
6. It has been over a year
If you cannot remember the last time the vent was cleaned, it is overdue. Most homes need it at least once a year.

How dangerous is a clogged dryer vent?
Very. Packed lint is highly flammable and traps heat, making clogged vents the leading cause of dryer fires. It also raises your energy bills.
Can I clean the dryer vent myself?
You can clean the lint screen and the immediate opening, but the full duct run, bends, and exterior hood are best cleaned professionally.
How long does dryer vent cleaning take?
Usually under an hour for a typical vent run, depending on its length and layout.
How often should I clean it?
At least once a year, and more often for large households, homes with pets, or long vent runs.
