What Houston's cold nights do inside your vent
Your dryer pushes warm, damp air out through the vent every time it runs. On winter nights here, averaging 45°F from December through February, that vent turns cold. The warm exhaust hits those cold walls and cools fast, and the moisture in it sticks. Lint clings to a damp wall far more than it does to a dry one, and it builds up layer by layer.
Once lint packs the vent, the dryer has to push air through a smaller opening. It runs hotter and takes longer to dry a load, and the lint sitting in there is what a dryer fire needs.

- How often should a dryer vent be cleaned?
- A contractor can tell you for certain once they see the length and shape of your vent run, but as a rule it needs cleaning before lint has a chance to pack it tight. A short, straight run stays clear longer than one with several turns or a long stretch to the outside wall. Drying times creeping up over several loads is usually the sign it is due.
- Can I clean my dryer vent myself?
- You can clean the first few feet near the machine yourself. A vacuum with a long hose or a vent brush kit reaches into the duct from the dryer end, and pulling the dryer away from the wall to disconnect the duct makes this easier. Getting the full length clean usually means reaching it from the outside vent hood too, and on a roof vent or a long duct run that gets hard to do safely on your own.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, or come out hot instead of just warm, are the first sign. You may also notice the outside of the dryer feels hot to the touch, the vent hood flap barely opens when the dryer runs, or there is a burning smell partway through a cycle. Lint collecting around the hood outside, or a musty smell from the laundry room, points to the same problem.
