Cold nights turn dryer lint into a wall inside your vent
Every load of laundry pushes warm, damp air through the vent to the outside. On a winter night here, when temperatures average 33°F, that warm air hits the cold metal of the vent and cools fast. The moisture in it has nowhere to go, so it beads up on the inside walls of the vent. Lint doesn't just float through after that. It sticks.
Layer by layer, that damp lint narrows the path the air has to travel. A vent that used to clear itself in a few minutes now holds heat and moisture longer, which gives the next load's lint even more to stick to. That buildup is what turns a slow dryer into a fire risk, and it is the reason the problem gets worse through the winter months, not better.

- 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, clean it more often. Lint builds up along the inside of the duct with every load, and that buildup is what slows the airflow and makes the dryer work harder.
- Can I clean my dryer vent myself?
- You can clean the first few feet near the dryer, but the full run is harder to reach. A vent brush kit will get lint out of the section right behind the machine. The rest of the duct, especially where it bends or runs up through the wall to the outside hood, needs a longer rod system to clear properly, and a contractor carries that equipment.
- What are the signs of a clogged dryer vent?
- Clothes coming out hot to the touch but still damp is the clearest sign. You may also notice the dryer taking longer than it used to, a burnt smell during the cycle, or the outside vent hood barely pushing out air when the dryer runs. Lint collecting around the lint trap door or the outside vent flap is another sign worth checking.
