Cold vents make lint stick
Every load pushes warm, damp air out through the vent. On a winter night, with the outside air averaging 31°F from December through February, that air cools fast once it hits the metal duct, and the moisture in it turns to damp inside the pipe. Lint sticks to a damp wall instead of blowing through to the outside.
That buildup narrows the path the air has to take. The dryer has to push harder to move the same air, and what does get through carries more heat and moisture into a duct that is already packed with lint.

- How often should a dryer vent be cleaned?
- Once a year is the standard rule, regardless of how often you run the dryer. Lint builds up along the duct walls a little at a time, and a year is about how long it takes to narrow the airflow enough to matter. If drying times have been creeping up, don't wait for the anniversary, have it looked at sooner.
- Can I clean my dryer vent myself?
- You can handle the lint trap and the first few feet of duct behind the dryer with a vent brush kit. The rest of the run to the outside wall is harder to reach, especially where it bends or travels through a floor or ceiling. A contractor has rods and a vacuum built for the full length, and can check the vent hood outside too, to make sure it opens freely when the dryer runs.
- What are the signs of a clogged dryer vent?
- Clothes taking more than one cycle to dry is the clearest sign. The dryer may run hotter than usual, and you might notice a warm or burnt smell partway through a cycle. Step outside while the dryer runs and check the vent hood. Little or no air coming out there means the duct is blocked somewhere along its length.
