Cold air turns dryer lint into a wall
Your dryer pushes out warm, damp air every time it runs. In a Liberty winter, with nights averaging 22°F from December through February, that air cools fast once it hits the vent. The moisture in it settles on the metal walls, and the lint in the exhaust sticks to it instead of blowing on outside.
Over a winter that runs October through April, that buildup narrows the vent a little at a time. A dryer that can't push air out has to work harder to dry a load, and the lint packed inside is what a dryer fire needs.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run large loads often or you have a longer duct run to the outside, check it more often since lint builds up faster in a longer vent. A vent that takes two cycles to dry a load needs cleaning sooner than that.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but that is not the whole job. Pulling the dryer out and vacuuming the first few feet of duct and the lint trap helps, but the rest of the run to the outside hood often needs a brush and rod long enough to reach it, plus access to clear the vent hood itself. A contractor has the tools to clean the full length and check that the hood flap opens and closes the way it should.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, a dryer that runs hot to the touch on the outside, a burning smell, or little to no airflow at the outside vent hood when the dryer is running. Lint around the lint trap door or the outside hood is another sign. Any of these on their own is worth checking, since a blocked vent makes the dryer work harder and raises the risk of fire.
