Cold air turns lint into a wall inside your vent
Your dryer pushes out warm, damp air, and from October through May that air is hitting a vent that runs through cold space most of the year. On a night near 11°F, the air cools fast once it leaves the drum. The moisture in it clings to the inside of the vent, and lint sticks to those damp walls instead of blowing on outside.
Over a winter that buildup narrows the vent a little at a time. Less air gets out, so the dryer runs longer to do the same load, and the exhaust that should leave the house lingers in the duct instead.

- How often should a dryer vent be cleaned?
- Once a year is the general rule, and it holds here too. A vent that stays clear also matters more in winter, since the dryer is one more thing running inside a closed-up house for the eight months a year this area needs heat. If the vent run is long or has several bends, lint has more places to catch, so it is worth a look between cleanings.
- Can I clean my dryer vent myself?
- You can clean the first few feet behind the dryer, but that is rarely where the real buildup sits. Most vent runs go through a wall and out to a hood outside, and lint tends to collect at the bends and at the hood itself. A contractor uses a brush and vacuum system built to reach the full length of the duct, which a household vacuum cannot do.
- What are the signs of a clogged dryer vent?
- Clothes that need more than one cycle to dry, a dryer that runs hot to the touch, and a burnt smell during the cycle are the main ones. Little to no airflow at the outside vent hood while the dryer runs, or a flap that will not lift, are also signs. Lint collecting around the hood opening outside is worth checking too.
