Cold air turns dryer lint into a wall
Every load sends warm, damp air out through the vent. In Elk River, that vent sits in a wall or attic that is cold nine months of the year. The air cools fast once it hits that cold metal, and the moisture in it beads up on the walls of the duct. Lint does not blow through wet duct walls, it sticks to them.
Each load adds another layer to what is already stuck there. The vent narrows, the dryer takes longer to dry a load, and the exhaust that should be leaving the house lingers in the duct instead.

- How often should a dryer vent be cleaned?
- A contractor can tell you based on how the vent looks when it's cleaned, but a dryer that runs longer than it used to is the real sign it's due. Households that dry more loads, or dry heavier loads like towels and bedding, will need it cleaned more often than that. Waiting for a problem to show up costs you less than waiting for it to get worse.
- Can I clean my dryer vent myself?
- You can clean the first few feet from the back of the dryer yourself. Unplug the dryer, pull it away from the wall, and clear lint from the exhaust port and the first section of duct with a vacuum or a brush made for this. Most vent runs go through a wall and out to a hood on the roof or siding, and the lint that collects deep in that run or at the hood itself is hard to reach without the right length of rod and a way to check that the hood flap is opening all the way. If your vent run is long or has more than one bend, a contractor can clean the whole length and confirm the hood is clear.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, or come out hot to the touch instead of just warm, are the clearest sign. Check the outside vent hood while the dryer runs. Weak airflow there, or a flap that barely moves, means lint is blocking the line. A burning smell, a dryer that shuts off mid-cycle, or heavy lint around the lint trap door are also signs the vent needs to be cleared.
