Cold vents make lint stick
Winter nights in Keene average 15°F from December through February. Your dryer pushes out warm, damp air, and when that air hits the cold metal of the vent, it cools fast. The moisture in it condenses on the walls of the duct, and lint sticks to that dampness instead of blowing outside.
That buildup narrows the vent over time. Your dryer has to push harder to move air through it, and wet lint clinging to the walls does not just fall back out on its own.

- How often should a dryer vent be cleaned?
- Once a year is the standard rule for most homes. If you run loads almost every day, or the vent run is long with a few bends in it, once a year is still the right interval, but it matters more that you actually keep to it. A dryer that takes longer than it used to, or feels hot to the touch on top, is telling you the vent needs attention sooner.
- 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 often. The rest of the run, especially where it goes through a wall or up to a roof or side vent hood, takes a brush system built for the full length of the duct. A contractor also checks that the vent hood flap opens freely and that the duct itself is metal, not the plastic or foil kind that traps lint and can catch fire.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry, or come out hot instead of cool at the end, are the clearest sign. Look also at the outside vent hood. If the flap barely moves when the dryer is running, air isn't getting through. A burning smell, more lint than usual around the lint trap, or a dryer body that feels hot on the outside all point the same way.
