Cold nights turn dryer lint into a wall inside your vent
Your dryer pushes warm, damp air through a vent that runs into cold air seven months a year. Winter nights here average 27°F. That warm air cools fast once it hits the cold metal, and the moisture in it settles on the vent walls. Lint sticks to damp walls far more than it does to dry ones.
Over a winter, that buildup narrows the vent from the inside. Air has a harder time getting out, so your dryer runs longer to dry the same load. The moisture that can't escape stays in the vent, and more lint catches there.

- How often should a dryer vent be cleaned?
- Once a year is the general rule, and if the dryer runs almost every day it needs checking more often than that. A load that takes longer to dry than it used to is a sign the vent needs attention sooner. Watch it closer during the colder months here, since a dryer that vents outside into cold air can build up moisture and lint faster.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of duct behind the dryer yourself. Most vent runs go through the wall and out to a hood outside, and that stretch is hard to reach without a rod and brush built for it. A vent that bends, runs long, or exits through the roof is harder still, and a shop vacuum pushed into the line usually packs the lint tighter instead of pulling it out. A contractor brings a rod system built to clear the full run and check that the hood flap outside opens and closes the way it should.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than they used to, or come out hot but still damp, are the clearest sign. A burning smell while the dryer runs, the dryer's outside casing feeling hotter than usual, and little to no airflow when you hold your hand near the vent hood outside are others. If the hood flap stays shut or barely moves when the dryer is running, lint is blocking the path.
