Cold makes the lint stick
Your dryer pushes warm, damp air out through the vent. Once that air hits the cold part of the run, it cools fast, and the moisture in it settles on the vent walls. Lint sticks to damp metal instead of blowing through to the outside. With winter nights here averaging 11°F, that cooling happens fast and close to the wall.
Over a season the lint builds into a clog. A clogged vent traps heat and moisture instead of releasing it outside, and that is what leads to long dry times and, in the worst case, a fire in the line.

- How often should a dryer vent be cleaned?
- A contractor can tell you for sure, but the usual guide is once a year. If you run loads almost every day, or your vent run is long, check it more often since lint builds up faster in both cases. A vent overdue for cleaning usually shows itself first through longer dry times.
- Can I clean my dryer vent myself?
- You can clean the section behind the dryer and the outside hood yourself, and that alone helps. What you can't easily reach is lint packed inside the duct run through the wall or ceiling, especially if it bends or travels a long distance. A contractor uses a brush and vacuum sized for the full length of the vent, which gets at what a homeowner can't reach from either end.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry, a dryer that runs hot to the touch, and a burnt smell during the cycle all point to a clogged vent. You might also notice little to no airflow at the outside vent hood when the dryer is running, or lint collecting around the hood flap. Any one of these on its own is worth checking, and if you see more than one together the vent likely needs clearing soon.
