Cold vents make lint stick
Your dryer pushes warm, damp air out through the vent, and when nights run 13 degrees the metal cools fast. That warm air hits the cold walls of the vent and the moisture in it beads up, and lint sticks to a damp wall a lot better than a dry one. Over time that buildup narrows the vent, and the dryer has to push harder to get the air out.
A vent that cannot breathe traps heat and moisture in the line instead of venting it outside. That is how lint fires start, and it is also why a dryer stops drying clothes in one cycle like it used to.

- How often should a dryer vent be cleaned?
- Once a year is the general rule, more often if you dry a lot of loads or you have a long vent run. Lint builds up along the duct even when the lint trap is clean, since the trap never catches all of it. A vent that runs longer than usual or takes several tries to dry a load is telling you it needs attention sooner than the yearly mark.
- Can I clean my dryer vent myself?
- You can clean the first few feet from the back of the dryer yourself, but the full run is harder to do right. Most vents have at least one bend, and lint collects at the bend and further down where a vacuum hose from your end cannot reach. A contractor uses a brush and rod system built to clear the whole length, including the hood outside where lint often packs in tight.
- What are the signs of a clogged dryer vent?
- Clothes coming out hot but still damp is the clearest sign. Others include the outside of the dryer getting hot to the touch, a burnt smell during the cycle, and little to no airflow at the outside vent hood when the dryer is running. Any one of these means air is not moving through the duct the way it should.
