What Danville winters do to a dryer vent
Your dryer pushes out warm, damp air every time it runs. In a Danville winter, with nights averaging 21°F from December through February, that air hits the cold metal of the vent and cools fast. The moisture in it turns back to water on the walls of the duct, and lint sticks to that wet surface instead of blowing through to the outside.
That buildup narrows the vent a little more with each load. Air backs up, the dryer runs hotter and longer to push clothes dry, and the lint packed inside the duct is exactly what a fire needs.

- How often should a dryer vent be cleaned?
- Once a year for most households, more often if you dry a lot of loads or have a long vent run with bends in it. Lint builds up along the inside of the duct even when the lint trap is clean, and it narrows the path air needs to escape through. A vent that takes longer than usual to dry a load, or feels hot to the touch on the outside, is telling you it needs attention sooner.
- Can I clean my dryer vent myself?
- You can handle the first few feet, but most of the vent run is out of reach without the right tools. A vacuum and a brush from the hardware store will pull lint from near the wall connection, but they will not reach a duct that runs any real distance or turns corners on its way outside. A rotary brush system built for this job can clear the full length, and a contractor will also check that the vent hood outside is opening properly and that the run is not longer than it should be.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry when they used to take one is the clearest sign. Others include the outside of the dryer feeling hotter than normal, a burning smell during a cycle, and the flap on the outside vent hood barely moving or staying shut while the dryer runs. Lint showing up around the door seal instead of in the trap is another sign air is not flowing the way it should.
