Cold vents make lint stick
Your dryer pushes out warm, damp air, and that air has to travel through a vent that sits in a cold attic or wall most of the winter. From December through February, nights here average 25°F, so the air cools fast once it leaves the drum. When it cools, the moisture in it settles on the vent walls, and lint sticks to that damp surface instead of blowing straight through to the outside.
Over time that buildup narrows the vent. Air moves slower, so the next load of exhaust cools even sooner, and more lint sticks. A vent in that state can't clear the moisture from a normal load, and the dryer ends up working harder to push air through it.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run big loads often, or you have a longer run of duct between the dryer and the outside wall, check it sooner. Lint builds up along the way, not just at the ends, and a year is usually enough time for it to narrow the vent down.
- Can I clean my dryer vent myself?
- You can clear the part you can reach, but that is usually just the first few feet. A vent brush kit will get lint out from the back of the dryer and a short way into the duct. The rest of the run, especially where it bends or climbs to an outside wall, needs a longer rod system or a shop vac with real reach, and a lot of homes have vent runs too long to clear by hand.
- What are the signs of a clogged dryer vent?
- Clothes coming out hot but still damp is the first sign. The dryer running longer than it used to for the same load, the top of the machine feeling hotter than normal, or a burnt smell partway through a cycle are others. Check the outside vent hood too. If the flap barely opens or doesn't open at all when the dryer is running, air isn't getting through.
