Cold air turns dryer lint into a wall inside your vent
Every load sends warm, damp air down the vent and out through the wall. When that vent runs through cold space, the air cools fast, and the moisture in it beads up on the metal walls before it ever reaches outside. Lint does not blow past that. It sticks.
On a night near 10 degrees, the whole run of pipe is cold from end to end, so the buildup does not stop at the first few feet. A vent narrowed by wet lint pushes hot, damp air back toward the dryer instead of outside, and that is what a clogged vent does to the house around it.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run the dryer daily, or the vent run is long with a lot of turns, clean it more often. Lint builds up along the inside of the duct even when the lint trap catches most of it, and a clean vent lets the dryer push hot air outside instead of fighting to move it.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but you likely cannot clean the whole vent yourself. A vacuum and a brush kit will get lint out of the first few feet behind the dryer and at the outside hood. What they will not reach is lint packed deep in a long run or around a bend, and that takes a rod system or a vacuum built for the job. If your vent run is short and straight, doing it yourself is reasonable. If it runs any distance through the house, have a contractor clean it.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, or come out hot to the touch instead of just warm, are the clearest sign. The outside vent hood should push out a steady flow of warm air when the dryer runs. If you feel little or nothing there, or the laundry room smells like hot lint, or the dryer itself is hot on the outside, the vent is blocked. A burning smell means stop using the dryer and have it checked before running it again.
