Cold air in the vent is what turns lint into a clog

Your dryer pushes out warm, wet air every time it runs. Once that air hits the cold metal of the vent, on a night that averages 19°F from December through February, it cools fast. The moisture in it settles on the vent walls, and the lint riding along with it sticks there instead of blowing outside.

That buildup narrows the vent a little more each time. Airflow drops, the dryer takes longer to dry a load, and the heat and moisture it can't push outside stay in the vent instead.

How often should a dryer vent be cleaned?
Once a year is the standard for most households. If you run the dryer every day or you're drying heavy loads like towels and bedding often, check it sooner than that. Lint builds up along the length of the vent, not just in the trap, and a year is usually how long it takes to narrow the airflow enough to matter.
Can I clean my dryer vent myself?
You can clean the parts you can reach, but most homes have a vent run that goes well beyond the back of the dryer. Pulling the dryer out and vacuuming the first few feet helps, and clearing the outside hood keeps that end open. The bends and the long straight sections in between need a brush and rod system built for the job, and that's where a contractor's equipment does more than a household vacuum can.
What are the signs of a clogged dryer vent?
Clothes that take two cycles to dry when one used to do it is the clearest sign. Others include the outside of the dryer feeling hotter than usual, a burnt smell during the cycle, and little to no airflow at the outside vent hood when the dryer is running. Lint collecting around the hood itself, or the flap not opening much, points the same way.
