Cold nights turn dryer lint into a damp clog

Your dryer pushes out warm, damp air every time it runs, and that air has to travel through a vent that sits in cold space most of the year. Carlisle winter nights average 24°F from December through February, so the air cools fast once it leaves the drum. Lint that would blow through a warm, dry vent instead sticks to walls that are cool and damp with condensation.

That buildup narrows the vent a little more with each load. A clogged vent traps heat and moisture behind it, and the dryer works harder to push air through.

How often should a dryer vent be cleaned?
Once a year for most households. Lint builds up along the whole run of the duct, not just at the trap, and a year is usually long enough for that to turn into a real blockage. A household that runs more loads through the week should have it checked more often.
Can I clean my dryer vent myself?
You can clean the first few feet from the back of the dryer yourself. Unplug the dryer, pull it out, and vacuum the duct and the wall opening you can reach. What you cannot do safely is clean the full run to the outside vent hood, especially if it goes through the attic or up more than one story. A contractor uses a rotary brush and a camera to get the whole length and to check that the vent hood itself is clear.
What are the signs of a clogged dryer vent?
Clothes that take more than one cycle to dry, a dryer that runs hot to the touch on top, and a burnt smell partway through the cycle. Check the outside vent hood too. If little or no air is moving out of it while the dryer runs, the duct is blocked somewhere between the dryer and the wall.
