Cold vents make lint stick

Your dryer pushes out warm, damp air. Once it hits the cold metal of the vent, that air cools fast, especially on nights that average 14 degrees here from December through February. Lint stops floating through and sticks to the damp walls of the duct instead.

That buildup narrows the path the air has to take. The dryer has to push harder to move the same load, and the exhaust that should leave your house stays trapped in the vent instead.

How often should a dryer vent be cleaned?
Once a year is right for most homes. A vent that runs long, or a dryer that feels hotter than usual partway through a cycle, can tell you it needs attention before the year is up. It is worth checking sooner rather than waiting if you notice either of those.
Can I clean my dryer vent myself?
You can clear the lint trap and the first few feet behind the dryer yourself. The rest of the run is harder to reach, especially where it bends or passes through a wall, and lint sitting further down will not show up until the vent is already restricted. A contractor has the brushes and rods to clean the full length and check that the vent hood outside is opening and closing the way it should.
What are the signs of a clogged dryer vent?
Clothes that take more than one cycle to dry, a dryer that runs hot to the touch, and a burning smell are the main ones. You might also notice less airflow at the outside vent hood when the dryer is running, or lint collecting around the hood itself. Any of these means air is not moving through the vent the way it should, and that is worth having checked before you run the dryer again.
