Cold vents make lint stick
Your dryer pushes out warm, damp air every load. Once that air hits the cold vent run, especially on a night near 16°F, it cools fast, and the moisture in it settles on the vent walls. Lint sticks to that dampness instead of blowing straight out. Layer by layer, the vent narrows.
A narrowed vent means air backs up. The dryer runs hotter and takes longer to dry a load, and warm moist air has nowhere to go but back into the house. That trapped lint is also the material that catches fire fastest of anything near the dryer.

- How often should a dryer vent be cleaned?
- Once a year is the standard rule, and it holds true here too. Lint builds up along the vent run every time you dry a load, and a year's worth is usually enough to start slowing the airflow. If you dry heavy loads often, towels, bedding, a big household's laundry, check it sooner rather than waiting the full year.
- Can I clean my dryer vent myself?
- You can clean the first few feet near the machine yourself, but that is not the same as cleaning the whole vent. Most dryer vents run several feet through a wall or up through the roof, with bends where lint collects out of reach of a home vacuum or a basic brush kit. A contractor uses a rod system or a vacuum built for the full length of the vent, including the outside hood where lint often packs in tight.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry instead of one is the clearest sign. Others include the top of the dryer feeling hot to the touch, a burning smell when it runs, and less lint than usual showing up in the lint trap because it is getting caught further down the vent instead. If the outside vent hood flap barely opens when the dryer is running, that is airflow telling you the same thing.
