Cold air in the vent is what turns lint into a clog
Your dryer pushes out warm, damp air, and that air has to travel through a vent that runs cold most of the year. Once the heat drops out of it fast, whatever lint is riding along sticks to the cold walls instead of blowing clear outside.
With winter nights here averaging 14°F from December through February, that vent stays cold for most of the run. Lint builds up layer on layer, and the path out gets narrower each month until the dryer is pushing air through a vent that barely lets it pass.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run loads almost daily, or the vent run is long with several bends, have it checked more often than that. Lint builds up along the duct walls whether you notice it or not, and a straight, short vent still needs the same yearly attention as a long one.
- Can I clean my dryer vent myself?
- You can clear the part you can reach, usually the first few feet behind the dryer and the outside hood, but that is not the same as cleaning the whole run. Most vents travel through walls or ceilings before reaching outside, and lint collects all along that path, not just at the ends. A contractor uses a brush and vacuum system built to reach the full length and clear it without damaging the duct.
- What are the signs of a clogged dryer vent?
- Clothes take longer than one cycle to dry, the dryer runs hotter than usual, or you smell something warm and dusty when it's running. Check the outside vent hood while the dryer is on. If the flap barely moves or you feel weak airflow, the duct is restricted somewhere between the dryer and the outside wall. A burning smell means stop the dryer and have the vent checked before running it again.
