Cold vents make lint stick

Your dryer pushes out warm, damp air, and from November through March that air hits a vent that's sitting cold, with nights averaging 37°F. The moisture in the exhaust condenses on those cold walls, and lint clings to the wet metal instead of blowing outside. Over time that buildup narrows the vent, and the dryer has to push harder to force air through it.

How often should a dryer vent be cleaned?
Once a year is the standard for most households, and a contractor can tell you if yours needs it sooner. Lint builds up along the inside of the duct even when the lint trap looks clean, and it narrows the path air needs to escape through. A household that dries clothes often or has a long duct run to get outside will fill that path faster.
Can I clean my dryer vent myself?
You can clean the section behind the dryer and the outside hood yourself, but the middle of the duct is hard to reach without the right brush and rod setup. If the vent run is short and straight, a vent brush kit from the hardware store will get most of it. Longer runs, runs with turns, or vents that go up through a wall need a contractor with the proper length rod to clear the whole line.
What are the signs of a clogged dryer vent?
Clothes taking more than one cycle to dry is the clearest sign. The top of the dryer may feel hot to the touch, and the outside vent hood will barely move air when you hold your hand near it while the dryer runs. A burnt smell during the cycle or more lint than usual around the lint trap door are also worth noting. Any one of these on its own is worth a look. A few together means the duct needs clearing soon.
