Cold vents make lint stick
Your dryer pushes out warm, damp air every time it runs. That air has to travel through a vent that sits in cold space, and from October through April, with winter nights here averaging 28°F, the vent itself stays cold most of the time it's working. Warm air hits those cold walls and cools fast. The moisture in it condenses, and lint sticks to the wet metal instead of blowing outside.
Once lint builds up along the vent, it holds onto more moisture and more lint, and the path out gets narrower. Air that used to clear the vent in seconds now takes longer, and the dryer works harder to push it through.

- How often should a dryer vent be cleaned?
- Once a year is the general rule, but how much you dry and how long your duct run is both change that. A short, straight run clogs slower than one with several bends or a long distance to the outside wall. If drying times have crept up since last year, that is a better signal than the calendar.
- Can I clean my dryer vent myself?
- You can handle part of it, but not the whole job. Pulling the dryer out and vacuuming the first few feet of duct helps, and so does clearing lint from the outside vent hood. The rest of the run, especially where it bends or passes through a wall, needs a brush and rod long enough to reach the full length, which most homeowners do not have on hand.
- 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 a load taking much longer than it used to, the outside vent hood barely moving air when the dryer runs, and a burning smell during the cycle. Any of these means air isn't moving through the duct the way it should, and it's worth having the vent checked before it gets worse.
