Cold nights turn dryer lint into a wet, sticky problem
Your dryer pushes warm, damp air through the vent every time it runs. On winter nights that average 32°F from December through February, that vent runs cold. The warm air hits those cold walls and cools fast, and the moisture in it has nowhere to go but the metal. Lint does not just blow through a vent like that. It sticks.
Once lint sticks, more lint sticks to it, and the vent narrows a little more each time you dry a load. A narrow vent means the dryer has to push harder to move the same air, and the exhaust that should be leaving your house lingers in the duct instead.

- How often should a dryer vent be cleaned?
- A contractor can tell you exactly what your vent needs, but the general rule is at least once a year. Run more loads than that, or have a long vent run with several bends, and you should clean it more often. A clean vent lets the dryer push hot, damp air all the way outside instead of trapping it in the line.
- Can I clean my dryer vent myself?
- You can clear the part you can reach, the section behind the dryer and a few feet into the duct. A vacuum with a hose attachment or a brush kit made for dryer vents handles that much. What you can't see is the rest of the run to the outside vent hood, and any bend in it can hold lint a vacuum from your end won't reach. A contractor can run a brush the full length and check that the vent hood flap opens and closes the way it should.
- What are the signs of a clogged dryer vent?
- Clothes coming out hotter than usual, or still damp after a full cycle, is the first sign. A burning smell while the dryer runs is another. Check the outside vent hood while a load is going. If you feel little or no airflow there, or the flap barely moves, lint is backed up somewhere in the line.
