Cold air in the vent is what causes the buildup
Your dryer pushes out warm, damp air every time it runs. From October through April, that air is moving through a vent sitting in cold space, with winter nights averaging 30°F. The warm air cools fast against those cold walls, and the moisture in it lets lint stick instead of blowing through to the outside.
That buildup narrows the vent a little at a time. A dryer that can't push air out has to work harder to dry a load, and the heat it can't vent has nowhere to go but back into the space around it.

- How often should a dryer vent be cleaned?
- A dryer vent should be cleaned once a year. Lint builds up along the inside of the vent every time the dryer runs, and it narrows the path the air has to travel. A yearly cleaning keeps that path clear so the dryer can push hot, damp air all the way outside.
- Can I clean my dryer vent myself?
- You can clean the first few feet from inside the house, but that only covers part of the run. Most vents travel through walls or ceilings to an outside hood, and lint collects along the whole length, not just at the ends. A contractor uses a brush and vacuum system built to reach the full run and clear the hood too.
- What are the signs of a clogged dryer vent?
- Clothes that stay damp after a full cycle, a dryer that runs hotter than usual, or a burnt smell when it's running. Check the outside vent hood too. If the flap barely moves or you don't feel much air coming out while the dryer runs, lint is likely blocking the path.
