Cold vents make lint stick

Your dryer pushes warm, damp air out through that vent. On a night that averages 20 degrees, the metal of the vent is cold clear through. The warm air cools fast against those walls, and the moisture in it turns to dampness on the way out. Lint does not just blow through anymore. It sticks.

That buildup narrows the vent a little at a time. A duct that cannot push air outside pushes the dryer's heat and moisture back into the house instead.

How often should a dryer vent be cleaned?
Once a year for most households. A dryer that vents through a long duct run or several bends can collect lint faster, so if yours takes longer than usual to dry a load, that's worth checking sooner. A clear vent also helps the dryer heat properly through the long stretch of cold months here.
Can I clean my dryer vent myself?
You can clean the lint trap and the first few feet of vent yourself, but most homes can't reach the whole run. The duct usually travels through a wall or ceiling before it reaches the vent hood outside, and lint collects at the bends you can't get to with a household vacuum. A contractor uses a brush and rod system built to clear the full length, including the hood itself.
What are the signs of a clogged dryer vent?
Clothes coming out hot to the touch but still damp is the clearest sign. Others include a musty smell in the laundry room, the outside vent hood flap staying shut when the dryer runs, and lint building up around the lint trap door even after you clean it. Any one of these on its own is worth a look, and if you notice more than one together, get the vent checked soon.
