Cold vents make the lint stick
Your dryer pushes warm, damp air out through the vent. Once that air hits the cold part of the run, the moisture in it turns back to water, and lint sticks to those wet walls instead of blowing outside. Winter nights here average 10°F from December through February, so that cooling happens fast, along most of the vent's length.
Once lint holds on inside, it doesn't loosen back up. More sticks to what's already there, the vent narrows, and the dryer has to push harder to move the same air out.

- How often should a dryer vent be cleaned?
- Once a year for most households. If several people share the dryer or you run it most days, check it more often than that. Lint builds up along the full length of the vent, not just in the trap, and enough of it will slow the airflow the dryer needs to work.
- Can I clean my dryer vent myself?
- You can clean part of it, but most homeowners cannot clean the whole run. A vent brush kit reaches the first several feet from the back of the dryer. The rest of the vent, especially where it bends or runs up through a wall to the roof or siding, needs a longer rod system or a vacuum built for the job. If your vent is long or has more than one bend, a contractor can run a brush the full length and check that the vent hood outside opens and closes the way it should.
- What are the signs of a clogged dryer vent?
- Clothes taking more than one cycle to dry is the clearest sign. The top of the dryer may feel hot to the touch, and the room where it sits can get warm and humid while it runs. You might also notice less air coming out of the vent hood outside than usual, or a burning smell. Lint trapped in the vent is a fire risk, so any of these signs is worth acting on.
