Cold vents make lint stick
Your dryer pushes warm, damp air out through the vent. On a night that averages 18°F, that vent is cold clear through, and the moment the warm air hits those cold walls it cools fast. The moisture in it turns back to water, and the lint riding along with it sticks instead of blowing clear out the hood.
That buildup narrows the vent a little more with every load. Air backs up, the dryer runs hotter and longer to get clothes dry, and the lint packed inside is exactly 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 the vent run is long with a lot of turns, check it more often since lint builds up faster in those setups. A clogged vent is a fire risk, so it's worth keeping to a yearly schedule even if the dryer still seems to work fine.
- Can I clean my dryer vent myself?
- You can handle the part you can reach, the section behind the dryer and a few feet into the wall, with a vent brush kit made for this. What you can't see is the rest of the run to the outside hood, and that's where lint tends to pack in tightest, especially at bends. A contractor has the rods and vacuum to clear the full length and check that the outside hood flap opens and closes the way it should.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry when one used to be enough is the biggest sign. Others are the top of the dryer feeling hot to the touch, a burnt smell during the cycle, or the outside vent hood barely moving when the dryer runs. Lint showing up around the door seal or in the lint trap slot itself is also a sign the vent behind it is backing up.
