Step 1 of 3: Equipment
Cold air turns lint into a wall in your vent
Your dryer pushes out warm, damp air every load. Once that air hits the cold vent run, especially on nights near 15°F, it cools fast and the moisture in it settles on the metal walls. Lint sticks to damp surfaces far more than dry ones, so it builds up in layers instead of blowing straight out.
Once that layer forms, less air gets out with each load. The dryer has to push harder to move the same air, and the vent stays wet longer after every cycle, which only helps the next layer of lint stick.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run loads daily or have a long vent run with a few turns in it, check it more often, since lint builds up faster in a duct that isn't a straight shot outside. A vent that's clogged makes the dryer work harder and run hotter, which shortens its life.
- Can I clean my dryer vent myself?
- You can clean the section from the dryer to the wall yourself, and the outside hood if you can reach it. What's harder to reach is the vent run inside the wall or through the roof, especially if it's long or has bends, and that takes a rod and brush made for the job. If lint keeps building up fast or you can't tell where the clog is, a contractor can run a full cleaning and check the vent hood flap while they're at it.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that runs hot to the touch, and a burning smell are the main signs. You might also notice the outside vent hood flap barely moves when the dryer is running, which means air isn't getting through. Lint around the lint trap door or a musty smell in the laundry room is worth checking too.
