Cold vents catch lint on the way out
Your dryer pushes warm, damp air outside through the vent. From October through May, that vent runs cold most of the day, and the air cools fast once it leaves the drum. Moisture beads up on the inside walls of the duct, and lint sticks to it instead of blowing clear.
Over a winter that buildup narrows the vent. Airflow drops, drying takes longer, and the exhaust that does get out has to push through less space. A vent that stayed clear in warmer months can choke down once the cold sets in.

- How often should a dryer vent be cleaned?
- Once a year is the general rule. Lint builds up along the whole length of the vent, not just in the trap, and it narrows the path the air needs to escape. A longer run, or one with several bends between the dryer and the outside wall, gives lint more places to catch, so those setups are worth checking on that same yearly schedule.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but that is usually just the first few feet. A vent brush kit sold for this job will get lint out of the section behind the dryer and into the wall. The rest of the run, especially if it bends or travels a long way to the outside wall, is hard to reach and easy to damage with the wrong tool.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, or come out hot instead of just warm, are the clearest sign. Check the outside vent hood while the dryer runs. If the flap barely moves or air is not pushing out, lint is blocking the path. A burning smell or a dryer that shuts off mid-cycle also points to restricted airflow.
