Cold vents catch more lint than warm ones
Every load of laundry pushes warm, damp air out through the vent. In winter, with nights averaging 31°F, that vent runs cold. The warm air cools fast against the metal, and the moisture in it beads up on the walls of the duct. Lint sticks to a damp surface far more than it does to a dry one, so the buildup happens faster than most people expect.
A vent that's losing ground keeps more of that moisture inside instead of carrying it outside. Lint packed into a damp vent restricts airflow, which means the dryer has to push harder to move the same air, and the exhaust has less room to clear the line.

- How often should a dryer vent be cleaned?
- Once a year for most households, though a contractor can tell you if your setup needs it more often. A dryer that vents straight out through a short, near-flat run tends to stay clear longer than one that snakes through a wall and attic with several bends. If you notice clothes drying slower than they used to, that is a sign to check it sooner rather than waiting for the year to be up.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet behind the dryer yourself. The rest of the run is harder to reach and harder to judge, since lint builds up along the whole vent, not just near the machine. Pulling the dryer out to check the connection is worth doing even if you have someone clean the full line.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that runs hot to the touch, and a burning smell are the main signs. You might also notice less airflow at the outside vent hood when the dryer is running, or lint collecting around the hood flap. Any of these on their own is worth looking into, and a burning smell means stop using the dryer until the vent is checked.
