Cold vents catch more lint
Your dryer pushes out warm, wet air every load. On a night near 34°F, that air hits the cold metal of the vent and cools fast, and the moisture it carries turns to dampness on the walls of the duct. Lint sticks to a damp wall far more than it does to a dry one, so the vent narrows from the inside out.
A narrowed vent forces your dryer to push harder to get the same air through, and the lint that built up on those cold walls does not go anywhere on its own.

- How often should a dryer vent be cleaned?
- Once a year is the usual rule, regardless of how much you use the dryer. Lint builds up a little with every load, and a year gives it enough time to narrow the duct without fully blocking it. If you run more loads than a typical household, or your duct run is long, watch how long clothes take to dry between cleanings. That will tell you sooner than the calendar will.
- Can I clean my dryer vent myself?
- You can clean the first few feet yourself, at the back of the dryer and where the duct meets the wall, with a vacuum and a long brush. What you usually cannot reach is the rest of the run out to the exterior hood, especially if it bends or travels through a wall cavity. A contractor uses a rod system or a vent-rated vacuum that reaches the whole length and clears the hood flap too, which is often where the buildup ends up.
- What are the signs of a clogged dryer vent?
- Clothes taking longer than one cycle to dry is the first sign. Others are the dryer or laundry room feeling hotter than usual while it runs, a burning smell, or the outside vent hood barely moving air when you hold your hand near it while the dryer runs. If lint is gathering at the hood itself, or the flap is not opening much, the vent is clogged and it is worth having it cleared rather than waiting for another sign.
