What cold winter nights do to a dryer vent
Your dryer pushes out warm, damp air every time it runs. Most of the year that air stays warm all the way through the vent to the outside. But on winter nights here, when temperatures drop into the 50s, the metal duct running through your attic or wall gets cold. The warm exhaust hits those cold walls and cools fast, and the moisture in it condenses. Lint sticks to a damp surface far more than it does to a dry one.
That buildup narrows the vent a little at a time. A duct that is partly blocked forces your dryer to push air through a smaller opening, and the moist air has less room to escape before it cools and drops more lint along the way.

- How often should a dryer vent be cleaned?
- Clean it at least once a year. A dryer pushes moist, lint-heavy air through that duct every time it runs, and lint builds up along the way even when the lint trap is clean. A vent that runs long or has several bends collects lint faster than a short, straight one, so those setups are worth checking sooner.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, the section behind the dryer and the vent hood outside. A full cleaning reaches the whole length of the duct, and that takes rods or a vacuum built for it, especially if the run is long or has bends. A contractor carries that equipment and can clear the whole vent in one visit.
- What are the signs of a clogged dryer vent?
- Clothes that are still damp at the end of a normal cycle is the clearest sign. A dryer that runs hotter than it used to, a musty smell while it runs, or heavy lint around the outside vent hood are others. If the hood flap does not open and close the way it should when the dryer is running, air is not moving through the duct the way it needs to.
