Cold winter nights turn dryer lint into a stuck-on problem
Warm, damp air moves down the vent and out through the wall every time the dryer runs. On a winter night here, with the temperature down near 26°F, that air cools fast once it hits the cold metal of the vent. The moisture in it beads up on the duct walls, and the lint riding along with the exhaust sticks to it instead of blowing outside.
That wet lint dries in place and builds a lining inside the vent. Each load adds a little more, narrowing the path the air has to travel. With less room for the exhaust to escape, the dryer has to push harder to get the same air out, and the heat and moisture have less way to go but back toward the house.

- How often should a dryer vent be cleaned?
- Once a year is the general rule for most households, and a contractor can tell you if your setup needs it more often. Vent runs with several bends or a long distance to the outside hood collect lint faster than a short, straight run. If you notice loads taking longer to dry, that is a sign to clean it sooner rather than waiting for the next scheduled time.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of duct you can reach, but most of the vent run is out of sight. It usually travels through a wall or ceiling before reaching the outside hood, and lint collects along that whole path, not just near the dryer. A contractor uses a brush and vacuum system made to clear the full length and check that the outside hood flap opens and closes the way it should.
- What are the signs of a clogged dryer vent?
- Clothes taking longer to dry, or coming out hot instead of just warm, are the clearest signs of a clogged vent. A dryer that feels hot to the touch on the outside, a burning smell during a cycle, and little or no lint in the trap after a full load are others. Check the outside vent hood as well. If the flap barely moves or you feel weak airflow while the dryer is running, lint is likely blocking the line.
