Cold vents catch more lint
Your dryer pushes out warm, damp air every load. From October through April, that air is moving through a vent that sits in cold space, with winter nights averaging 28°F. The air cools fast against those cold walls, and the moisture in it makes the lint stick instead of blowing through to the outside.
Over a winter that buildup narrows the vent. Air backs up, the dryer runs hotter and longer, and a vent that is mostly blocked is a fire risk sitting behind your wall.

- How often should a dryer vent be cleaned?
- A good rule is once a year. If you do laundry for a large family, or your duct run is long or has several bends, check it more often, since lint builds up faster in those setups. A vent that takes longer than it used to dry a load is telling you it is due.
- Can I clean my dryer vent myself?
- You can clean the section right behind the dryer and the outside hood yourself, and that is worth doing between full cleanings. The parts you cannot see, the run through the wall and the roof or wall cap, need a brush and rod long enough to reach the whole duct, plus a way to confirm it came out clean at the other end. A contractor has both.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry, or come out hot to the touch instead of just warm, are the clearest sign. Check the outside hood while the dryer runs. Weak airflow there, or almost none, means lint is blocking the duct somewhere between the dryer and the wall. A burning smell or a dryer that shuts off mid cycle means stop using it and get the vent checked.
