Cold vents give lint somewhere to stick
From October through April your dryer is pushing warm, damp air out through a vent that sits in a cold house or a cold attic. Winter nights here average 30°F, so that exhaust cools fast once it leaves the drum. When it cools, the moisture in it condenses on the inside of the vent, and lint sticks to those damp walls instead of blowing outside.
Over a winter that buildup narrows the vent. Air moves slower, so the load of exhaust behind it cools and drops moisture even sooner. It builds on itself the colder it gets.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run several loads a day or have a long duct run from the dryer to the outside wall, check it sooner. The vent hood flap outside should swing open freely when the dryer runs. If it barely moves, lint has already built up.
- Can I clean my dryer vent myself?
- You can clean the section behind the dryer yourself, but the full duct run is harder to reach. Pull the dryer out, disconnect the duct, and vacuum out what you can reach from both ends. A rigid or semi-rigid duct with bends, or one that runs any real distance to the outside wall, usually needs a brush and rod long enough to clear it end to end. If you cannot see daylight through the duct when it is disconnected, a contractor has the tools to clear it fully.
- What are the signs of a clogged dryer vent?
- Clothes take more than one cycle to dry, or come out hot to the touch but still damp. The outside of the dryer feels hotter than usual, or you smell something warm and dusty when it runs. Lint around the outside vent hood, or a flap that will not open all the way, both mean air is not moving through like it should. Any of these on their own is worth checking before you run another load.
