Cold vents make lint stick
Your dryer pushes out warm, damp air, and that air is heading through a vent that sits in the cold for most of the year. Winter nights here average 21°F from December through February, and a vent running through that cold pulls the heat out of the exhaust fast. When the warm air cools that quickly, moisture collects on the inside of the vent, and lint sticks to the wet walls instead of blowing outside.
Over a winter that buildup narrows the vent. Air moves slower, the dryer takes longer to dry a load, and the motor works harder to push air through a passage that is closing in.

- How often should a dryer vent be cleaned?
- Once a year is the standard. Here that cleaning is worth scheduling before September, when heating season starts and the dryer goes into steady use through the cold months. A clean vent lets it dry clothes without fighting a restricted line all winter.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but that is usually not the whole vent. A brush kit clears lint from the section right behind the dryer, and that is worth doing between full cleanings. The rest of the run, especially where it bends or where it exits the wall, takes a longer rod system or a shop vac with real reach, and that is the part most vent fires start in.
- What are the signs of a clogged dryer vent?
- Clothes taking longer than one cycle to dry is the first sign most people notice. A dryer running hotter than usual, a burnt smell, or the outside vent hood barely moving when the dryer runs are the others. Lint building up around the lint trap door or behind the dryer is worth checking too. Any of these means air is not moving through the vent the way it should, and it is worth having looked at soon rather than waiting.
