Cold vents turn lint damp, and damp lint sticks
Your dryer pushes out warm, damp air every time it runs. In Cumberland, that vent run sits in a cold space eight months of the year, December through February nights average 24°F, and the warm air cools fast once it hits the metal. When it cools, the moisture in it settles on the walls of the vent, and lint sticks to the damp spots instead of blowing on through. Load by load, that buildup narrows the vent until the dryer is pushing air through a smaller and smaller space.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run large loads often or dry a lot of towels and bedding, lint builds up faster and it is worth checking sooner. A vent that runs long or straight to the outside wall stays clearer longer than one with several turns or a long run through the house.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet behind the dryer yourself, and you should do that between professional cleanings. But the full duct run to the outside vent hood usually takes a brush and rod system built for the job, and if the vent has more than one bend or runs any real distance, a contractor has the tools to clear it end to end. Pulling the dryer out to check the connection is also a good habit, since a crushed or disconnected duct will not show up any other way.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, or come out hot and still damp, are the clearest sign. You may also notice the outside of the dryer getting hot, a burning smell, or the flapper on the outside vent hood barely moving when the dryer runs. If lint is visibly collecting around the vent hood outside, that is a sign the duct behind it is holding onto more than it should.
