Cold vents make lint stick
Your dryer pushes warm, wet air out through that vent. From October through May, the metal it's traveling through is cold, sometimes down around 21 degrees on a winter night. The air cools fast once it hits that cold duct, and the moisture in it goes onto the walls of the vent. Lint sticks to wet metal a lot better than it sticks to dry metal.
That buildup narrows the path the air has to take. A dryer that can't push air out has to work harder to dry a load, and the heat it's not venting outside stays in the duct instead.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you dry a load almost every day, or you're drying for a large family, the lint builds up faster and the vent is worth checking more often than that. Homes here need heat running October through May, and a clogged vent that's forcing the dryer to work harder is not something you want to find out about in the middle of that.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but most homes can't get the whole vent run that way. Pull the dryer out, disconnect the vent at the back, and vacuum out what you find there and in the lint trap housing. The rest of the run, especially where it bends or goes up through a wall or roof, needs a brush system long enough to reach the outside hood, and that's the part a contractor is set up to do properly.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry, or come out hot to the touch and still damp, are the clearest sign. Check the outside vent hood while the dryer runs. If the flap barely moves or you feel weak airflow, lint is building up somewhere in the run. A burning smell, a dryer that runs hotter than usual, or heavy lint around the lint trap door are also signs worth acting on.
