Cold makes the lint stick
Your dryer pushes warm, damp air out through the vent. Once that vent runs through cold space, the air inside it cools fast. Moisture beads up on the walls of the duct, and lint sticks to the damp metal instead of blowing straight through to the outside.
With winter nights here averaging 3°F, that cooling happens fast and it happens for months. Layer by layer, the vent narrows. A narrow vent means your dryer takes longer to dry a load, and it means more heat and lint sitting inside the duct instead of leaving your house.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run large loads often, or your vent run is long with a few turns in it, have it checked more than once a year. Lint builds up along the whole length of the duct, not just at the lint trap, so a yearly cleaning keeps air moving the way it should.
- Can I clean my dryer vent myself?
- You can clean the first few feet from the back of the dryer yourself, but that is not the whole vent. Most runs go through a wall and out to a hood, often with at least one bend, and a household vacuum or brush kit will not reach past those turns. A contractor uses a rod and brush system built for the full length, including the vent hood outside, which is where a lot of lint actually collects.
- What are the signs of a clogged dryer vent?
- Clothes coming out hot to the touch but still damp is the clearest sign. Others are a dryer that takes longer than it used to, a burning smell during the cycle, and the flap on the outside vent hood barely moving or not moving at all when the dryer runs. If the top of the dryer feels hot while it is running, that also points to airflow that is not getting out.
