Step 1 of 3: Equipment
Cold vents trap the lint your dryer pushes out
Your dryer pushes out warm, damp air every time it runs. That air has to travel through a vent that sits in cold space, in the wall or the attic, and on a night near 29 degrees the warm air cools fast once it hits the metal. When it cools, the moisture in it beads up on the inside of the vent, and lint sticks to a damp wall instead of blowing straight through to the outside.
Once lint builds up along that wall, the vent narrows. Air that should carry all the way outside starts backing up instead, and the dryer has to push harder to move it.

- How often should a dryer vent be cleaned?
- Once a year is a good baseline for most homes. If you run several loads a day or your vent run is long or has a lot of bends, lint builds up faster and you may want to check it more often. Drying times creeping up is usually the vent telling you it's due sooner.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but that's usually just the first few feet near the dryer. Most vent runs go through a wall or up through the roof, and lint collects the whole way along, especially at bends. A shop vac and a brush kit handle the section near the dryer, but a full cleaning reaches the vent hood outside too, and a contractor has the rods and equipment to do that safely.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than usual to dry, or that come out hot to the touch at the end of a cycle, are the first sign. The outside of the dryer may feel warmer than normal, and you might notice weak airflow at the vent hood outside, or almost none at all. A burning smell is a sign to stop using the dryer and have the vent checked right away.
