Cold vents trap the lint your dryer pushes out
Your dryer pushes out warm, damp air every time it runs. In a cold vent, that air cools fast, and the moisture in it turns to dampness on the inside walls of the duct. Lint sticks to damp metal instead of blowing straight through to the outside hood.
With lows averaging 34°F for three months of the year, and heat needed in the house from October through June, the vent runs cold most of the time your dryer is on. That buildup narrows the path air has to take, and a dryer that cannot push air out freely takes longer to dry a load and runs hotter while it does.

- How often should a dryer vent be cleaned?
- Once a year for most households. If the vent run is long, has several bends, or goes up through the roof, lint catches in those spots first and the vent may need attention sooner than that. Watch for the signs of a slow dryer between cleanings rather than waiting out the full year on a fixed schedule.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of duct yourself, but that is not the whole vent. Most runs go through a wall or up through the roof to a hood outside, and lint builds up in the bends and at the far end where a household brush cannot reach. A contractor uses a rod and brush system built to clear 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 coming out hot but still damp after a full cycle is the clearest sign. Others are a dryer that runs noticeably longer than it used to, the outside of the dryer feeling hot to the touch, a burning smell, or little airflow at the vent hood outside when the dryer is running. Lint gathering around the lint trap door or a hood flap that will not open all the way also point to a blocked vent.
