Cold vents give lint a place to stick
Every load sends warm, damp air down the vent and out. From October through April, that vent runs through a house working to keep out nights near 31°F. The air cools fast on the way through, and the moisture in it settles on the vent walls. Lint sticks to a damp wall much easier than a dry one, and it builds up in layers.
A vent that's narrowing with lint pushes exhaust out slower, so the dryer takes longer to do the same job. Left long enough, that buildup blocks the vent enough to stop it from clearing out the moist air at all.

- How often should a dryer vent be cleaned?
- Once a year is enough for most homes. Lint builds up along the whole length of the vent every time you run a load, not just in the lint trap, and a year is about how long it takes to narrow the airway enough to matter. If drying times start creeping up before then, it is worth checking sooner rather than waiting for the date on the calendar.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but that is usually not the whole vent. A vacuum at the wall hood and a brush a few feet into the duct will pull out what collects near the ends. The stretch of duct in between, especially if it runs any distance to an outside wall or through the attic, needs a rod-and-brush system built for the full length. A contractor can also check the outside hood to make sure it opens freely and closes against wind.
- What are the signs of a clogged dryer vent?
- Clothes that take longer to dry than they used to, or come out hot to the touch instead of just warm, are the first sign. You may also notice the outside vent hood barely moves when the dryer runs, or lint gathering around the hood itself. A burning smell, or the dryer shutting off on its own, means air is not moving through and it needs attention right away.
