Cold vents catch more lint than warm ones
Your dryer pushes out warm, damp air, and that air has to travel through a vent that sits in a cold space most of the year. From December through February, nights here average 22°F, so the vent itself runs cold. When warm exhaust hits those cold walls, it cools fast, and the moisture in it beads up on the metal. Lint sticks to a damp surface far more than it does to a dry one, so it builds up along the seams and at every turn instead of blowing straight through to the outside.
With heat needed here from October through May, that cold stretch runs eight months of the year, which is most of the time your dryer is venting into a cold duct. A vent that stays clear when it is warm can start trapping lint once the cold sets in.

- How often should a dryer vent be cleaned?
- Once a year is the standard most manufacturers recommend, and it holds for most households. If the dryer runs almost every day, have it checked sooner. The vent carries lint the trap never catches, and that buildup is what turns a normal load into one that takes two cycles to dry.
- Can I clean my dryer vent myself?
- You can clean the first few feet near the dryer yourself, but you cannot reach the whole run. Most vents travel through a wall or ceiling to the outside, with bends you cannot see around or reach with a household vacuum. A contractor uses rods and a brush sized to the duct to clear it end to end, including the flap at the outside hood where lint also collects.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, or come out hot instead of just warm, are the clearest sign. Check the outside vent hood while the dryer runs. If the flap barely moves or you feel weak airflow, lint is blocking the path. A burning smell or a dryer that shuts off mid-cycle also points to a blocked vent and should not wait.
