Cold vents make lint stick harder
From October through May your dryer is pushing warm, damp air through a vent that runs into cold air, sometimes down near 23 degrees on a winter night. That warm air cools fast once it hits the cold metal, and the moisture in it beads up on the walls of the vent. Lint doesn't just blow through anymore. It sticks.
Over a season that buildup narrows the vent and slows the airflow the dryer depends on to push exhaust outside. A dryer that can't vent properly runs hotter and takes longer to dry a load, and the lint packed inside is exactly what a vent fire needs.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run big loads often, or you've got a long duct run to the outside, clean it more often than that. A vent that's clear moves hot moist air out fast, so your dryer isn't fighting to push air through lint buildup.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of duct yourself, but that's not the whole vent. Most runs bend through walls or up through a roof or wall cap, and lint collects at every turn, not just near the machine. A vent cleaning kit with a rotating brush reaches further than a vacuum hose alone, but a contractor with a full-length rod system and a camera can confirm the whole run is actually clear, not just the part you can reach.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry is the biggest one. Others include the outside of the dryer running hot to the touch, a burning smell during the cycle, the vent hood flap barely moving when the dryer runs, and heavy lint around the lint trap or the outside vent opening. Any one of these on its own is worth checking, and if you notice more than one at the same time, don't wait on it.
