Cold vents catch more lint
Your dryer pushes out warm, damp air every time it runs. That air has to travel through a vent that sits in a cold house for eight months of the year, October through May, with winter nights averaging 14°F. When the warm exhaust hits those cold walls, it cools fast, and the moisture in it beads up before it ever reaches outside.
Lint sticks to a damp surface far more than a dry one. Instead of blowing straight through, it clings to the inside of the vent, layer on layer, narrowing the path the air has to take. The tighter that path gets, the longer it takes to clear the moist air out of your dryer, and the more lint has a chance to catch on the way.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run loads almost every day, or the vent run is long with a lot of turns, clean it more often than that. A clogged vent makes the dryer work harder to push air through, and that strain is what leads to lint fires.
- Can I clean my dryer vent myself?
- You can clean the first few feet from the back of the dryer yourself, and that's worth doing. A vacuum with a hose attachment and a basic brush kit will pull out the lint that collects right at the connection. The part you can't reach this way is the full run to the outside hood, especially if it bends through walls or a long stretch of ductwork, and that's where the buildup that actually blocks airflow tends to sit.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than usual to dry, or come out hot to the touch but still damp, are the clearest sign. Check the outside vent hood too. If the flap barely moves or you don't feel much air pushing out while the dryer runs, the line is restricted somewhere along its length. A burning smell or more lint than normal around the lint trap door are also signs worth acting on right away.
