Cold vents make lint stick
Your dryer pushes warm, damp air out through the vent. Once that air hits the cold duct, it cools fast, and the moisture in it turns to dampness on the vent walls. Lint sticks to a damp surface instead of blowing through, and it builds up layer by layer.
Homes here need heat from October through May, eight months of the year, and winter nights average 20°F from December through February. For most of the year, the vent is cold enough to turn that exhaust damp before it clears the house.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run big loads often, or your vent run has a long stretch with a lot of bends, clean it more often than that. Lint builds up inside the duct even when the lint trap looks clean, and that buildup is what causes the problems.
- Can I clean my dryer vent myself?
- You can clean the first few feet from the back of the dryer yourself, but that only reaches part of the duct. Most vent runs have bends and a long stretch to the outside wall, and lint collects past where a homeowner's brush or vacuum can reach. A contractor uses rods that run the full length and clear the vent hood at the outside end too.
- 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 on the outside, and a burning smell during the cycle are the main ones. Check the vent hood outside while the dryer runs. If you feel weak airflow there, or the flap barely opens, lint is blocking the duct somewhere between the dryer and the wall.
