Cold air turns dryer lint into a wall
Your dryer pushes warm, wet air out through the vent. Once that vent runs through cold space, the air inside it cools fast. Batesland winter nights average 15°F, so a vent running through an unheated wall or attic hits that cold air within a few feet of the wall.
Moisture in the exhaust hits the cold metal and turns to damp film on the walls of the vent. Lint sticks to wet surfaces the way it never would to dry ones, and it builds up layer by layer instead of blowing clear. Over a winter that runs October through May, that buildup can choke the vent enough to slow the airflow your dryer depends on to push exhaust outside.

- How often should a dryer vent be cleaned?
- Once a year is the usual rule, more often if you run a lot of loads or have a long duct run to the outside. Lint builds up along the way even when the lint trap gets cleaned every time. A vent that is choked with lint makes the dryer run hotter and longer, and that heat has nowhere to go but back into the room or the wall the duct runs through.
- Can I clean my dryer vent myself?
- You can clean the first few feet near the machine yourself, but the full duct run is hard to do right without the proper brushes and rods. Most vents run several feet through a wall or ceiling before reaching outside, and lint collects at every bend along the way. A contractor can run a brush the full length and check that the vent hood outside is opening and closing the way it should.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry, a dryer that runs hot to the touch, and a burning smell are the clearest signs. Check the outside vent hood too. If the flap barely moves or no air is coming out while the dryer runs, lint is likely blocking the line somewhere between the machine and the outside wall.
