Cold vents make lint stick
Every load of laundry pushes warm, damp air out through the vent. From December through February, the outside end of that vent sits in air that averages 25°F. The warm air cools fast once it hits that cold metal, and the moisture in it has nowhere to go but back onto the walls of the vent. Lint sticks to a damp surface much easier than a dry one, and it builds up there instead of blowing outside.
That buildup narrows the vent a little more with each load. Air moves slower through it, the dryer runs longer to do the same job, and the lint sitting in a duct that runs through your house is the kind of thing that should not be there.

- How often should a dryer vent be cleaned?
- Once a year, at minimum. Lint builds up along the whole length of the vent, not just in the trap, and that buildup is what slows the dryer down and raises the risk of fire. If you notice any of the signs of a clog before the year is up, don't wait for the schedule, get it checked then.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but most of the vent runs where you cannot see it. A vacuum and a brush from the dryer end will pull lint out of the first few feet. The rest of the run, especially where it bends or where it exits the wall, needs a rod and brush system built for the full length, and a contractor has those tools.
- What are the signs of a clogged dryer vent?
- Clothes take longer to dry than they used to, or come out still damp after a full cycle. The outside of the dryer feels hot to the touch, or the laundry room gets warmer than usual while it runs. You may also notice little to no airflow at the outside vent hood when the dryer is on, or a burning smell. Any one of these means the vent needs a look.
