Cold vents catch more lint
Your dryer pushes out warm, damp air, and that air has to travel through a vent that sits in a cold space most of the year. From December through February, nights here average 17°F, and the vent line cools fast between loads. When that warm air hits the cold metal, moisture beads up on the walls of the vent, and lint sticks to it instead of blowing on outside. Layer by layer, the vent narrows.
A vent that's losing airflow makes the dryer work harder to push air through, and the exhaust that should exit outside starts to linger in the line. That trapped lint is the part that needs clearing out before it builds into a real blockage.

- How often should a dryer vent be cleaned?
- Once a year is the standard advice for most households, and a household that dries a lot of loads a week should check it more often than that. A vent that's clean moves air freely, and that's what keeps drying times short and keeps lint from building up where you can't see it. If drying times start creeping up between cleanings, that's the vent telling you it's due early.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet behind the dryer yourself, and you should do that often. But the full vent run to the outside wall is a different job. It often has bends, it may run a long distance through the house, and lint hides in those bends where a vacuum hose can't follow. A contractor uses brushes and rods built to clear the whole line, not just the part you can reach.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than usual to dry, or that come out hot to the touch but still damp, is the clearest sign. Others are a burning smell while it runs, a dryer that gets hotter than normal on the outside, or the flap on the outside vent hood barely moving when the dryer is on. Lint building up around the lint trap slot faster than it used to is another one worth paying attention to.
