Cold vents make lint stick
Your dryer pushes out warm, damp air every load. From October through April, that air is moving through a vent that sits in cold space, and on a winter night here it might only be 31°F outside the wall. The warm air cools fast once it hits that cold metal, and the moisture in it settles on the vent walls. Lint sticks to a damp surface far more than it does to a dry one.
Once lint builds up along those walls, the vent narrows. Air moves slower, so the exhaust stays wet longer, and more lint sticks on the next load. That buildup is what turns a vent from a clear path outside into a blocked one.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you dry a lot of loads, have a long vent run, or share a machine among several people, check it more often. A vent that's clogged makes the dryer run hotter and longer, and that heat has nowhere good to go.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet behind the machine yourself, and you should do that often. The rest of the run is harder to reach and harder to judge from the outside, especially where the duct bends or passes through a wall. A contractor uses a brush and vacuum made to clear the full length, including the vent hood outside.
- What are the signs of a clogged dryer vent?
- Clothes take longer to dry than they used to, or come out hot instead of just warm. The dryer itself may feel hot to the touch on the outside, and you might notice a burning smell or more lint than usual around the lint trap. Check the vent hood outside too. If the flap barely opens when the dryer runs, or lint is caught around it, air isn't moving through like it should.
