Cold nights turn dryer lint into a damp, sticky problem
Your dryer pushes out warm, damp air every time it runs. On winter nights that average 30°F, that air hits the cold walls of the vent and cools fast. The moisture in it has nowhere to go, so the lint riding along with it stops drifting and starts sticking.
That buildup narrows the vent a little more each month. A dryer that can't push air out won't dry clothes the way it should, and the damp lint packed inside stays wet against the metal for months at a time.

- How often should a dryer vent be cleaned?
- Once a year is the standard advice for most households. Lint builds up along the whole length of the vent, not just at the trap, and a year is usually long enough for enough of it to collect and slow the airflow. A household running the dryer more than most, or one where the vent run is long, may need it checked sooner.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but that is rarely the whole vent. A vent brush kit will get lint out of the first few feet from the back of the dryer. Most runs continue on through the wall or up through the roof, and that stretch needs a longer rod system or a shop vacuum with the right attachment to clear all the way to the outside hood.
- What are the signs of a clogged dryer vent?
- Clothes coming out hot to the touch but still damp is the clearest one. Others include a musty smell in the clothes, the dryer running longer than it used to for the same load, and the outside vent hood barely moving air when you hold your hand near it while the dryer runs. Lint collecting around the door seal or the outside hood flap not opening are worth checking too.
