Cold nights turn dryer lint into a wall inside your vent
Every load pushes warm, damp air out through the vent, and on a winter night that averages 31°F, that air cools fast once it hits the metal. Lint that would blow straight out on a warm day sticks to the cold, damp walls instead and builds up layer by layer. Over a season it narrows the path the air has to take.
A vent that cannot push air out all the way keeps that damp air moving slower, and slower air drops more lint before it ever reaches outside. That is how a vent goes from clear to blocked without anyone touching it.

- How often should a dryer vent be cleaned?
- Once a year is the standard advice for most households. Lint builds up along the inside of the duct even when the outside vent hood looks clear from the yard. A vent that's clogged makes the dryer run hotter and take longer to dry a load, which wears on the heating element over time.
- Can I clean my dryer vent myself?
- You can clean the first few feet from the back of the dryer yourself, but the full duct run is harder to reach. Most vents run several feet through a wall or ceiling before reaching the outside hood, with bends a household brush can't get around. A shop vac and a brush kit will pull out what's near the opening, but lint further down the line needs a longer rod system or a vacuum made for the job to clear it completely.
- What are the signs of a clogged dryer vent?
- Clothes coming out hot to the touch but still damp is the clearest sign. Others include the outside vent hood flap barely moving when the dryer runs, a burning smell during a cycle, and the dryer itself getting hot on the outside. If drying times have been creeping up load after load, the vent is the first thing to check.
