Cold vents make the lint stick

Your dryer pushes out warm, damp air. Once that air hits the cold vent run, it cools fast, and Preston nights average 16°F from December through February. The moisture in the exhaust condenses on the walls of the vent, and lint sticks to the damp metal instead of blowing outside.

That buildup narrows the vent a little more each time you run a load. A clogged vent backs up hot, damp air into the duct, and in the worst case, into the house.

How often should a dryer vent be cleaned?
Once a year is the standard answer for most households. Lint builds up along the whole length of the duct, not just in the trap, and that buildup restricts airflow even when the trap is clean. If the dryer is taking longer to dry clothes than it used to, that is a sign to have it checked sooner rather than waiting out the year.
Can I clean my dryer vent myself?
You can clean the parts you can reach, but a vent kit with flexible rods only helps on a straight run to the wall cap. Bends, long runs, and vents that exit through the roof instead of a wall are where most lint collects, and a shop vac from either end will not reach that far in. A contractor working from both ends with the right length of rod can clear the whole run, not just the parts near the openings.
What are the signs of a clogged dryer vent?
Clothes coming out hot to the touch but still damp after a full cycle is the clearest sign. Others include the dryer running noticeably longer than it used to, the outside vent hood flap barely moving or not moving at all when the dryer runs, and a burning smell during the cycle. A dryer that shuts off partway through a load can also mean the internal thermal switch is tripping from heat that has nowhere to go.
