Step 1 of 3: Equipment
Cold nights turn lint into a wall inside your vent
Every load sends warm, damp air out through the vent. On a night near freezing, that air cools fast against the metal, and the moisture in it turns the lint sticky instead of letting it blow clear outside. Layer after layer builds up on the vent walls until the passage narrows and the dryer has to push harder to get air out at all.
Raleigh winter nights average 32°F from December through February, cold enough to chill that exhaust before it clears the vent.

- How often should a dryer vent be cleaned?
- Once a year is the general rule, and households that run the dryer daily should have it checked more often. Lint builds up along the inside of the duct even when the lint trap looks clean, and that buildup is what slows the dryer down and raises the risk of fire. A contractor can tell you what the vent run in your house calls for.
- Can I clean my dryer vent myself?
- You can clean the first few feet near the back of the dryer yourself, but that rarely reaches the real clog. Most vent runs go through a wall and out to a hood outside, and lint tends to collect farther down the line or right at the hood flap. A proper cleaning uses a brush and vacuum built to run the full length of the duct, which is hard to do with a shop vac and a broom handle.
- 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 main ones. You might also notice lint coming out at the outside vent hood, or the hood flap barely moving when the dryer runs. Any of these means air isn't getting out the way it should, and it's worth having the vent checked before running the dryer again.
