What Columbia winters do to a dryer vent
Every load of laundry pushes warm, damp air through the vent to the outside. On a winter night, with the temperature averaging 36°F, that air cools fast once it hits the metal duct, and the moisture in it settles on the walls of the vent. Lint sticks to a damp wall far better than a dry one, so the buildup packs in tighter and holds on.
A vent losing airflow this way takes longer to push air out, and the dryer runs longer to dry the same load. Left alone, the blockage gets worse each winter, from November through March, and the risk that goes with a clogged vent grows with it.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run a load almost every day, or your vent run is long or has several bends to get outside, check it sooner. A vent that stays clean also helps the dryer heat properly through the cold months here from November through March.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of the vent yourself, but the rest of the run is harder to reach and harder to check. A vent brush kit will get some lint out near the dryer, but it will not tell you if the vent is crushed, sagging, or blocked further down where you cannot see it. A full cleaning reaches the whole line, including the hood outside where lint tends to build up.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, a dryer that feels hot to the touch on the outside, and a burning smell during a cycle are the main signs. You might also notice little to no airflow at the outside vent hood when the dryer is running, or the room getting warmer and more humid than usual. Any of these means the vent needs a look before you run the dryer again.
