Cold vents catch more lint than warm ones

Every load pushes warm, damp air out through the vent. On a winter night that averages 33°F, that air cools fast against the cold metal, and the moisture in it turns the lint sticky instead of letting it blow straight through. Sticky lint clings to the wall of the vent instead of riding the air outside.

That buildup narrows the path a little more with each load. The dryer has to push harder to move the same air, and the lint sitting in a cold, damp vent is exactly what a clogged vent needs to become a fire risk.

How often should a dryer vent be cleaned?
Once a year is the general rule for most households. If you run large loads often, or you have a long vent run with a lot of bends, check it sooner because those setups trap lint faster. A vent that takes longer than usual to dry clothes is telling you it needs attention now, not on a schedule.
Can I clean my dryer vent myself?
You can clean the part you can reach, which for most homes is the section behind the dryer and a short run to the wall. The trouble is the rest of the vent, especially where it runs through the wall or up to the roof or side wall hood. A contractor uses a brush and vacuum system built to reach the full length and pull lint out instead of pushing it further in.
What are the signs of a clogged dryer vent?
Clothes that take more than one cycle to dry, a dryer that runs hotter than usual, or a burning smell when it's running. Check the outside vent hood while the dryer runs. If you feel weak airflow there, or the flap barely moves, lint is building up somewhere in the line. Lint around the dryer's lower panel or a hot dryer surface are also worth acting on.
