Cold nights turn dryer lint into a wall inside your vent

Your dryer pushes warm, damp air out through the vent. Winter nights here average 42°F, and that air cools fast against the metal walls on its way out. The moisture in it turns the lint sticky instead of letting it blow straight through, and that sticky lint catches the next load's lint behind it.

A vent narrowing this way makes the dryer work harder to push air out. It also means more heat and moisture stay trapped in the line instead of venting outside, right where the lint is building up.

How often should a dryer vent be cleaned?
Once a year is the standard advice, and it holds for most households. If the duct run from the dryer to the outside wall is long, or it has several bends, lint builds up faster at each turn and the vent needs checking more often. A contractor who cleans it can tell you how that vent is doing and whether your schedule should be shorter.
Can I clean my dryer vent myself?
You can clean the part you can reach, but that is usually not the whole job. Pulling the dryer out and vacuuming the first few feet of duct, plus clearing the outside vent hood, catches a lot of lint. What you cannot see is the rest of the run behind the wall, and if your duct bends or runs any distance, lint collects at every turn. A contractor uses a brush and rod system built to clear the full length, and can tell you if the duct itself needs repair.
What are the signs of a clogged dryer vent?
Clothes that take more than one cycle to dry is the clearest sign. Others include the outside of the dryer feeling hot to the touch, a burnt smell during the cycle, the vent hood flap barely moving or not moving at all when the dryer runs, and lint showing up around the dryer door or on the floor behind it. Any one of these means air is not moving through the duct the way it should, and it is worth having the vent checked before it gets worse.
