Cold air turns dryer lint into a wall inside the vent
Your dryer pushes out warm, damp air every time it runs. Once that air hits the cold metal of the vent, it cools fast, and the moisture in it settles on the walls of the duct. Lint sticks to that dampness instead of blowing on outside. On a night near 17°F, the cooling happens within the first few feet of duct, so lint can build up close to the wall rather than at the outside hood where it would be easy to spot.
A vent that is narrowing with lint takes longer to clear the air, which means more moisture stays trapped in the line each time you run a load. That trapped moisture is what lets lint bind together and build faster the next time.

- How often should a dryer vent be cleaned?
- Once a year is the standard rule, more if you dry heavy loads like towels and bedding often. Lint builds up along the duct every time you run a load, and it does not clear itself out. A vent that runs long or has several bends collects lint faster than a short, straight one, so those setups may need a look more than once a year.
- Can I clean my dryer vent myself?
- You can handle the part right behind the dryer and at the outside hood, but the full duct run is harder to reach on your own. A vacuum and a long brush kit will get lint out of the sections you can access. If your duct is long, has turns, or runs through the attic or a wall cavity, a contractor has the tools to clear the whole length and check that the vent hood flap opens freely from outside.
- 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. Others include a burning smell during the cycle, the dryer running hotter than usual, or lint showing up around the outside vent hood. Any of these means air is not moving through the duct like it should, and it is worth having the vent checked before the dryer is run again.
