Cold vents make lint stick

Your dryer pushes out warm, damp air, and that air has to travel through a vent that sits in cold space most of the year. From December through February, nights here average 25°F, so the metal cools fast between loads. Warm air hits those cold walls and the moisture in it settles out, and lint clings to a damp surface instead of blowing through to the outside.

Over a winter that runs eight months long, that buildup narrows the vent a little at a time. A dryer that can't push air out freely takes longer to dry a load and runs hotter doing it.

How often should a dryer vent be cleaned?
Once a year for most households. If you run big loads often, or have a long duct run from the dryer to the outside wall, check it sooner. Lint builds up inside the vent even when the lint trap is cleaned every load, because the trap only catches part of it.
Can I clean my dryer vent myself?
You can clean the parts you can reach, but that is usually not the whole job. A vacuum and a brush kit will get lint out of the first few feet behind the dryer. The rest of the run, especially where it bends or passes through a wall, needs a longer brush and someone who can get to both ends of it.
What are the signs of a clogged dryer vent?
Clothes that take longer than one cycle to dry, or come out hot to the touch, are the clearest sign. Check the outside vent hood too. If the flap barely moves or you feel weak airflow when the dryer is running, lint is blocking the path. A burning smell or a dryer that shuts off mid-cycle means it is overheating and should be looked at right away.
