Cold vents turn dryer lint into a wall of buildup
Your dryer pushes out warm, damp air every time it runs. From October through May, the metal vent it's traveling through is sitting in a house working against 19°F nights. That warm air cools fast against the cold vent walls, and the moisture in it turns the lint into a paste that sticks instead of blowing outside. Over a winter, that buildup narrows the vent until less air gets out with each load.
A vent that can't clear itself is a vent that traps heat and moisture right where the lint is stuck. That's the setup for a slow-drying dryer and, over time, a fire risk inside the wall.

- How often should a dryer vent be cleaned?
- Once a year, more if you dry a lot of loads or the vent run is long. Lint builds up along the way and narrows the path air needs to take. A vent that's clogged makes the dryer run hotter and longer to dry the same load, and that heat has nowhere good to go.
- Can I clean my dryer vent myself?
- You can clean the first few feet, from the back of the dryer to where the vent meets the wall, with a vent brush kit. What you can't reach is the rest of the run through the wall or ceiling to the outside hood, and that's usually where the worst buildup sits. A contractor runs a brush the full length and checks that the vent hood flap outside opens freely.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that runs hot to the touch, and a burnt smell partway through the cycle. Check the outside vent hood while the dryer runs. If the flap barely moves or no air is coming out, the line is blocked somewhere between there and the dryer.
