Cold air turns dryer lint into a wall of buildup

Your dryer pushes out warm, damp air every time it runs. That air has to travel through a vent that sits in a house built for winter nights averaging 1°F. The vent walls are cold, so the warm air cools fast, and the moisture in it turns to dampness on the way out. Lint sticks to a damp wall far more than it does to a dry one, and it builds up layer by layer.

Once that lint packs in, the vent cannot move air the way it should. Moist air backs up instead of clearing the line, and a blocked vent is a known cause of house fires.

How often should a dryer vent be cleaned?
Once a year for most households. If you run large loads often, or the vent run is long, have it checked more than that. Homes here run the furnace from September through June, so the dryer vent is one more thing worth keeping clear through most of the year rather than just in summer.
Can I clean my dryer vent myself?
You can clean the lint trap and the first few feet of duct yourself, but the full vent run is harder to reach. Lint collects at bends in the duct and at the outside hood, spots you can't easily see or get a brush into. A contractor has the tools to clear the whole line, not just the part within reach.
What are the signs of a clogged dryer vent?
Clothes that take longer than usual to dry, or come out hot to the touch, are the first sign. You may also notice the dryer running hotter than usual, a burnt smell, or weak airflow at the outside vent hood when it's running. Lint building up around the lint trap faster than normal is another clue. Any of these means air isn't moving through the duct the way it should.
