Cold vent walls catch more lint
Your dryer pushes out warm, damp air, and that air has to travel through vent that sits in a cold space most of the year. Winter nights here average 16°F from December through February, and heat is running in the house from October through May. When the warm exhaust hits that cold metal, it cools fast, and the moisture in it beads up on the vent walls. Lint sticks to a damp surface far more than a dry one, so the buildup packs in tighter along the run instead of blowing straight out.

- How often should a dryer vent be cleaned?
- Once a year is the general rule, though how much you use the dryer matters more than the calendar. A household running loads every day builds up lint faster than one running a few loads a week. If clothes are taking longer to dry than they used to, that is the vent telling you it needs cleaning now, not at the year mark.
- Can I clean my dryer vent myself?
- You can handle the lint trap and the first few feet behind the dryer yourself. A vent brush kit reaches further into the duct than a vacuum can, but lint sitting past a bend is hard to reach without the right length of rod and a way to check it actually came loose. If the vent run is short and straight, doing it yourself is reasonable. If it turns corners or runs any real distance, a contractor with a full rod kit can confirm the whole line is clear, not just the part you can reach.
- What are the signs of a clogged dryer vent?
- Clothes that need more than one cycle to dry is the clearest sign. Others include the outside of the dryer feeling hot to the touch, a burning smell during the cycle, the vent hood flap barely moving when the dryer runs, and lint showing up around the door seal. Any one of these means air is not moving through the vent the way it should, and a clogged vent is a fire risk, not just an inconvenience.
