Cold vents catch more lint
Every load sends warm, damp air out through the vent. On a night near 28°F, that air cools fast against the cold metal, and the moisture in it turns to condensation on the walls of the duct. Lint sticks to that dampness instead of blowing through to the outside.
With winter running from October through April, the vent spends most of the year cold enough for this to happen. The buildup narrows the duct, the dryer takes longer to dry a load, and the motor works harder to push air through the blockage.

- How often should a dryer vent be cleaned?
- Once a year for most households, less if the dryer runs daily. Homes here need heat running October through April, and a dryer vent that's already restricted works against a furnace trying to keep up on the coldest nights. If drying times start creeping up before a year is out, that's the vent telling you it's due early.
- Can I clean my dryer vent myself?
- You can clean the section right behind the dryer and the outside vent hood yourself. A vacuum with a hose attachment reaches the first few feet, and pulling the dryer out to check the connection is worth doing regularly. The trouble is the rest of the duct running through the wall or ceiling, since lint builds up along the whole length and most homeowners don't have a brush long enough or stiff enough to reach it. A contractor uses rods that run the full duct and pull lint out from end to end.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that feels hot to the touch on the outside, and a burning smell when it runs are the clearest signs. Check the outside vent hood while the dryer runs. If you feel weak airflow or don't see the flap move much, lint is likely blocking the duct somewhere along its length. A clogged vent also pushes warm, moist air back into the house instead of outside, worth catching before the cold nights settle in.
