Cold vents make lint stick
Your dryer pushes out warm, damp air every time it runs. That air has to travel through a vent that sits in cold space, and here that space is cold most of the year. From December through February, nights average 13°F, so the vent walls are cold too. The warm air cools fast once it hits that metal, and the moisture in it lands on the lint instead of carrying it outside.
Once lint is damp, it doesn't blow through anymore. It sticks to the wall of the vent and the next load adds to it. Over a winter that buildup can narrow the vent enough to slow the airflow your dryer depends on.

- How often should a dryer vent be cleaned?
- Once a year is the general rule for most dryers. Lint builds up along the whole length of the vent, not just in the trap, and a year is usually long enough for it to start restricting airflow. If you notice drying times getting longer before then, that's a sign the vent needs attention sooner.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach. Pulling the dryer out and clearing the first few feet of duct helps, and cleaning the lint trap after every load matters too. A vent that runs long, has several bends, or goes up through the roof is harder to clear end to end without the right brushes and rods, and a contractor with that equipment can reach the parts you can't.
- What are the signs of a clogged dryer vent?
- Clothes taking two cycles to dry when one used to be enough is the clearest sign. The outside vent hood flap should open and move air while the dryer runs. If it barely moves, air isn't getting through. A burning smell, a dryer running hotter than usual, or heavy lint around the trap area are also signs the vent needs attention.
