Warm air hits a cold vent and the lint stays behind
Your dryer pushes out warm, damp air every time it runs. On a winter night here, when temperatures average 54 degrees, that air cools fast once it hits the vent, and the moisture in it makes the lint stick to the walls of the duct instead of blowing through to the outside hood.
That buildup narrows the path the air has to take. A dryer working against a blocked vent runs hotter and takes longer to dry a load, and the lint sitting in there is what a dryer fire needs.

- How often should a dryer vent be cleaned?
- Once a year is the general rule, though a household running the dryer daily or a vent run with several turns needs it more often. Lint builds up inside the duct even when the trap is cleared before every load, because the trap only catches what passes through it. Left long enough, that buildup turns into a blockage that slows drying and strains the dryer.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but that is usually not the whole vent. Pulling the dryer out and vacuuming near the connection, and clearing lint from the outside hood, are both worth doing. The trouble is the duct itself, which often runs through the wall or attic and turns corners you cannot reach with a household vacuum. A contractor uses a brush and rod system built to travel the full length of the duct and clear it out.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, or come out hot instead of just warm, are the clearest sign. Check the outside vent hood too. If the flap barely moves or you feel weak airflow with the dryer running, lint is backing up somewhere in the duct. A burning smell during a cycle means it needs attention right away.
