Cold nights turn dryer lint into a wall of buildup
Every load sends warm, damp air down the vent and out. On winter nights that average 29°F, that air cools fast against the cold metal, and the lint riding along with it sticks to the damp walls instead of blowing clear. Load after load, that buildup thickens.
A vent losing airflow this way runs hotter and takes longer to push air out. That is more heat sitting in a duct packed with lint, which is exactly what dryer fires need.

- How often should a dryer vent be cleaned?
- A contractor can tell you for certain, but the usual advice is about once a year. If you run large loads often, or your vent run is long with a lot of turns, it is worth checking more than once a year. Lint builds up along the inside of the duct even when the lint trap is clean, and that buildup is what slows the dryer down and puts strain on the heating element.
- Can I clean my dryer vent myself?
- You can clean the first few feet from the back of the dryer, but you can't reach the whole run. Most vents go through a wall or up through the roof, with bends you can't see around or reach with a vacuum. A contractor uses a brush and rod system built to travel the full length and pull lint out at the vent hood, not just push it further down the line.
- 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. Check the outside vent hood too. If the flap barely moves or doesn't open at all when the dryer runs, air isn't getting out and lint is building up somewhere in the line.
