Warm air meets a cold vent, and lint stays behind
Every load pushes warm, damp air out through the vent. On winter nights that average 33°F from December through February, that vent runs cold almost the whole way through. The air cools fast once it hits the metal, and the moisture in it has somewhere to go. Lint that would otherwise blow out the hood sticks to those damp walls instead.
Layer after layer, that buildup narrows the path the air has to take. A duct that's choked with lint forces the dryer to push harder and run hotter to get the same load dry.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run big loads often, or if the vent run is long or has several turns, ask a contractor whether your home needs it more often. Lint builds up along the way and a straight, short duct clears itself out better than one that bends through walls or a long attic run.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but that is not the whole job. Pull the dryer out, disconnect the duct at the back, and clear lint from that section and from the outside vent hood with a brush. The lint further down the duct, especially past any bends, needs a rod or a vacuum system built for the full run, and a contractor has both.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than they used to, or come out hot instead of dry, are the first sign. The top of the dryer feels hot to the touch, the vent hood outside barely puffs air when the dryer runs, or you smell a burning lint smell partway through a cycle. Any one of these means air is not moving through the duct the way it should, and that lint is sitting somewhere it shouldn't be.
