Cold vents give lint somewhere to stick
Your dryer pushes warm, damp air out through the vent. From October through April, that vent runs through space that sits near the winter air outside, and on nights that average 29°F the metal inside the vent turns cold fast. Warm air hitting a cold vent wall cools down and drops the moisture it was carrying, and that dampness is what makes lint stick instead of blowing straight through to the outside.
Once lint sticks, more lint catches on it. The vent narrows, the dryer takes longer to get clothes dry, and the exhaust has less room to escape.

- How often should a dryer vent be cleaned?
- Once a year is the standard rule. Lint builds up along the whole length of the duct, not just at the trap, and a year of normal use is enough to pack it tight. If the duct run is long or has several bends, a contractor may recommend cleaning it more often.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but most of the duct is behind the dryer and inside the wall, out of reach of a vacuum or a brush from the hardware store. A contractor uses a rotating brush on a long cable that reaches the full run, from the back of the dryer to the vent hood outside. If your vent run is short and straight, pulling the dryer out and vacuuming the first few feet plus the vent hood outside will help between full cleanings.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than they used to, or come out hot but still damp, are the first sign. The top of the dryer feels hot, the laundry room feels warmer than usual, or you notice a burning smell during the cycle. Check the vent hood outside too. If little air is moving out of it while the dryer runs, the duct is blocked somewhere along its length.
