Cold nights turn dryer lint into a wall of buildup
Every load of laundry pushes warm, damp air out through the vent. On a night that averages 24°F, that air cools fast against the cold metal walls, and the moisture in it turns the lint sticky instead of letting it blow through. Layer by layer, that damp lint builds up along the duct.
A vent choked with lint cannot push exhaust all the way outside. Air backs up, the dryer takes longer to dry a load, and the lint packed inside the duct is exactly what a stray spark needs to catch.
- 24°F

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run the dryer more than average, for a large family or a home where towels and bedding get washed often, clean it more often than that. A vent that stays clear also lets the dryer shut off when clothes are actually dry, instead of running longer to make up for weak airflow.
- Can I clean my dryer vent myself?
- You can clear the lint trap and the first few feet of duct yourself with a vent brush kit made for this. What you can't easily reach is the rest of the run behind the wall and the hood outside where it exits, and that's where lint tends to build up worst. A contractor can run a full-length brush or camera through the whole vent and confirm the outside hood is actually flapping open when the dryer runs.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that feels hot to the touch on top, and a burning smell when it runs are the main signs. Check the outside vent hood too. If the flap barely moves or you feel weak airflow there while the dryer is on, the duct is likely restricted somewhere along the run.
