Cold vents make lint stick
Your dryer pushes warm, damp air out through the vent. From December through February, nights here average 15°F, and that vent runs cold most of its length. The warm air cools fast once it hits that cold metal. The moisture in it has to go somewhere. It lands on the walls of the vent, and lint catches there instead of blowing clear.
Once lint packs into a bend or a joint, the vent stays wet longer after every load. Wet lint holds together. The clog grows from there.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run several loads a day, or notice drying times creeping up, have it checked sooner rather than waiting out the year. A vent that stays clear also matters more here, since the dryer will be working through eight months of heating season and you want it running right.
- Can I clean my dryer vent myself?
- You can clear the lint trap and the first few feet behind the dryer yourself, and that is worth doing. Getting the full run clean is harder, since the vent often travels a long distance to the outside wall or roof and bends along the way. A contractor uses a brush and vacuum built for the full length of the duct, including the vent hood outside where lint builds up unseen.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, or come out hot to the touch but still damp, are the clearest sign. Check the outside vent hood too. If the flap barely opens when the dryer runs, or you feel little to no airflow there, lint is likely blocking the line. A burning smell during a cycle means stop using the dryer and have the vent checked before running it again.
