Cold vent walls catch the lint your dryer pushes out
Your dryer pushes out warm, damp air every time it runs. Once that air hits the cold metal of the vent, it cools fast, and on a winter night averaging 27°F, it cools within feet of leaving the house. The moisture in it beads up on the vent walls, and lint sticks to that dampness instead of blowing on through to the outside.
That buildup narrows the vent a little more each month, and from October through April the vent stays cold enough for it to keep happening. A vent that is choked with lint makes the dryer work harder to push air through, and it gives that lint more chances to catch on something warm.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run big loads often or you have a longer duct run to the outside, check it sooner. Lint builds up inside the vent even when the lint trap looks clean, and that buildup is what slows the dryer down and raises the risk of fire.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but most of the vent is not one of them. Pull the dryer out, disconnect the duct, and clear out what you find there and in the lint trap housing. The rest of the run, especially where it bends or goes up through a wall or roof, needs a vent brush kit long enough to reach the outside hood, and most homeowners do not have one. A contractor with the right equipment can clear the full length in one visit and check that the outside hood is opening and closing the way it should.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that gets hotter than usual on the outside, or a burning smell when it runs. You might also notice less airflow coming from the outside vent hood when the dryer is on, or lint collecting around the hood itself. Any of these on their own is worth looking into, since a blocked vent traps heat and lint together.
