Cold nights turn dryer lint into a stuck-on layer

Every load sends warm, damp air down the vent and out through the wall. Oakland winter nights average 41°F, so that air cools fast once it hits the metal duct. Lint that would blow through a warm, dry vent sticks to the damp walls instead.

Layer by layer, that buildup narrows the vent. Air moves slower, so the next load takes longer to dry and leaves behind even more lint. A vent that stays blocked keeps warm, wet air trapped in the duct instead of pushing it outside.

How often should a dryer vent be cleaned?
Once a year is the standard most contractors work from. Lint builds up inside the duct even when the lint trap is clean between loads, and that buildup is what slows drying time and puts strain on the heating element. A longer vent run or one with several bends collects lint faster than a short straight one, so those may need a look sooner.
Can I clean my dryer vent myself?
You can clean the first few feet from the back of the dryer, but that is not the whole vent. Most runs go through a wall or attic space before reaching the outside hood, and lint collects the whole way there. A contractor uses a brush and vacuum sized for the full length of the duct, including any bends, and checks that the outside hood opens and closes the way it should.
What are the signs of a clogged dryer vent?
Clothes that take two cycles to dry, a dryer that runs hot to the touch, and a burning smell are the main ones. Check the outside vent hood too. If little to no air is coming out while the dryer runs, or the flap barely moves, the duct is likely blocked somewhere in between.
