Cold vents catch more lint
Your dryer pushes out warm, damp air every load. Once that air hits the cold metal of the vent, it cools fast, and lint sticks to damp walls instead of blowing straight outside. From October through April, with winter nights averaging 27°F, that vent stays cold most of the time your dryer runs.
A vent that narrows with lint makes the dryer work harder to push air out, and it takes longer for clothes to dry. Left alone, that buildup is also fuel sitting in a hot exhaust path.

- How often should a dryer vent be cleaned?
- Once a year is the standard advice, and it holds up whether the dryer runs a couple loads a week or one every day. Watch the dryer between cleanings too. If a load that used to dry in one cycle now needs two, the vent is telling you it is getting blocked before the year is up.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of duct behind the dryer yourself. The rest of the run is harder to reach, especially where it bends through a wall or up through a roof, and a shop vac or a hardware store brush will not clear lint packed further down the line. A contractor has rods and brushes built to reach the full length and can also check that the vent hood outside is opening and closing the way it should.
- What are the signs of a clogged dryer vent?
- Clothes coming out hot to the touch but still damp is the clearest sign. Others include a burning smell during the cycle, the outside vent hood barely pushing out air when the dryer runs, and lint collecting around the vent opening outside. A dryer running noticeably hotter or longer than it used to is also worth checking, since a blocked vent traps heat that should be venting outside.
