Cold vents catch more lint than warm ones
Your dryer pushes out warm, damp air every time it runs. That air has to travel through a vent that sits in a cold attic or along an unheated wall for part of the winter, and winter nights here average 26°F from December through February. When the warm exhaust hits that cold metal, moisture forms on the inside of the vent, and lint sticks to it instead of blowing straight through to the outside.
Over a season that buildup narrows the vent. The dryer has to push harder to move the same air, and the lint that collects near the wall or roof cap is what a vent fire needs.

- How often should a dryer vent be cleaned?
- Once a year is the standard rule for most households. If you dry large loads often, or you have a long duct run to the outside, check it partway through the year as well. A vent that runs longer than usual on a normal cycle is telling you it needs attention sooner.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but most homeowners cannot clean the whole run. A vacuum and a brush kit will get lint out of the first few feet behind the dryer, and that helps. The rest of the duct, especially where it bends or runs through a wall to the outside, needs a longer brush and a job better left to someone who does this for a living.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than they used to, or come out hot to the touch but not fully dry, are the clearest sign. A burning smell, a dryer that runs hotter than normal, or lint collecting around the outside vent hood are others. If the vent hood flap outside barely moves when the dryer runs, air isn't getting through the way it should.
