Cold nights make the lint stick
Your dryer pushes out warm, damp air, and that air has to travel through a vent that runs through cold space before it reaches outside. On nights that average 42°F from December through February, the vent walls are cold enough that the moisture in the exhaust condenses on them. Lint sticks to a damp surface far more than it does to a dry one, so the buildup packs in tighter over those months.
A vent that's losing airflow to lint takes longer to clear the moist air out of the line. That damp air has to go somewhere, and it either backs up toward the dryer or sits in the duct where it keeps feeding the buildup.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run big loads often, or you're drying towels and bedding several times a week, have it checked more often than that. A clean vent lets your dryer push hot air outside instead of holding it in the duct, which is what keeps drying times short and keeps lint from building up where you can't see it.
- Can I clean my dryer vent myself?
- You can clean the first few feet from the back of the dryer yourself, and that's worth doing between full cleanings. A vacuum with a hose attachment reaches that section fine. But most vents run several feet through the wall to an outside hood, with at least one bend, and that part needs a rod or brush system built for the job. If you've never had the full length done, or you don't know how long yours runs, a contractor can clear it end to end and check that the outside hood opens and closes the way it should.
- What are the signs of a clogged dryer vent?
- Clothes coming out hot but still damp after a full cycle is the biggest one. Others are a dryer that runs noticeably longer than it used to, the top of the dryer feeling hot to the touch, a burning smell, or lint finding its way out around the door. Outside, check the vent hood while the dryer runs. If you don't feel much air coming out, or the flap barely moves, that's a clogged line.
