Cold vents turn damp lint into a clog fast
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. Once winter nights drop to 13 degrees, the air cools fast inside that metal duct. When it cools, the moisture in it condenses on the walls of the vent, and lint sticks to wherever it's wet.
That buildup narrows the path the air has to take. A dryer working against a clogged vent runs longer to dry the same load, and the heat and damp lint have nowhere to go but back toward the machine.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run large loads often, or you have a longer duct run to the outside, check it sooner. Lint builds up inside the vent even when the lint trap is cleaned every load, because the trap only catches what passes through it near the door.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but most of the vent runs where you can't see it. A vacuum at the wall opening only pulls lint from the first foot or two. The rest of the run, especially where it bends or where it exits outside, needs a brush and rod pushed through the full length, which is what a contractor brings.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that runs hot to the touch, and a burning smell are the main signs. Check the outside vent hood too. If the flap barely moves or stays shut while the dryer runs, air isn't getting through. A weak or musty smell at the vent opening outside, instead of a strong warm airflow, points the same way.
