Cold vents catch more lint
Every load of laundry pushes warm, damp air out through the vent. In a Lenoir City winter, with nights averaging 32°F from December through February, that warm air hits cold metal and cools fast. The moisture in it beads up on the vent walls, and lint sticks to the damp spots instead of blowing straight through.
That buildup narrows the vent a little more with each load. A dryer that can't push air out has to work harder to dry anything, and the lint left behind is the kind of thing that starts a fire.

- How often should a dryer vent be cleaned?
- Once a year is the standard, more often if you dry a lot of loads or the vent run is long. Lint builds up along the way even when the lint trap is clean, and it narrows the path the air needs to escape. A longer vent, or one with several bends, traps more lint and may need attention more than once a year.
- Can I clean my dryer vent myself?
- You can clean the first few feet from the back of the dryer, but most of the vent run is out of reach without the right tools. A vent brush kit with flexible rods can reach further, though most home ducts run through walls or the roof where lint collects out of sight. A contractor who does this for a living can run a brush the full length of the vent and check the hood outside is opening and closing the way it should.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that runs hot to the touch, and a burning smell are the clearest signs. Lint building up around the lint trap door or a weak flap at the outside vent hood point the same way. If the top of the dryer feels hot during a cycle, air is not moving through the vent like it should, and that is worth having checked.
