Cold vents give lint a place to stick
Your dryer pushes out warm, damp air. From November through April, that air is moving through a vent that sits in a cold space, and on nights that average 41°F, the air inside the vent cools fast. Lint carried along in the damp air sticks to the walls instead of blowing straight through.
Once lint builds up, the vent can't move air the way it should. The dryer runs longer to dry the same load, and the heat it produces has less way in and out. A clogged vent is also a fire risk, since lint is what catches.

- How often should a dryer vent be cleaned?
- Once a year is the standard most contractors work from. Lint builds up inside the duct even if you clean the lint trap every time, and it builds up whether the run is short or long. A vent that stays clogged makes the dryer work harder and run hotter, and that heat has nowhere to go but back into the room or into the wall around the duct.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but you likely cannot clean the whole vent. A vacuum and a brush from the dryer side will pull out lint near the opening, and doing that regularly helps. Most vent runs bend through a wall or up through a roof, and lint collects at those bends where a homeowner can't reach it. A contractor uses a rod and brush system built to clear the full length of the duct.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry is the clearest sign. Others include the outside of the dryer feeling hot to the touch, a burning smell during a cycle, the vent hood flap barely moving when the dryer runs, and heavy lint around the lint trap or the vent opening outside. Any one of these means air isn't moving through the duct the way it should, and it's worth having the vent checked before running more loads.
