Cold vents and damp air don't mix
Your dryer pushes out warm, wet air every time it runs. That air has to travel through a vent that sits in cold space, and on winter nights here that average 38°F, the vent walls are cold too. The warm air cools fast against them, and the moisture it's carrying turns damp lint into something that sticks rather than blows through.
Once that damp lint clings to the inside of the vent, more lint catches on it, and the passage narrows. Air stops moving the way it should, so your dryer runs hotter and takes longer to finish a load. A vent that's choked with lint is also a vent that's holding a lot of dry fuel next to a heat source.

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run large loads often, or you have a long vent run to the outside, once a year is still the mark to aim for, but check it partway through the year too. Lint builds up inside the duct even when the lint trap looks clean, and that buildup is what causes the problems.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but you likely cannot clean the whole vent. Pulling the dryer out and vacuuming the first few feet of duct and the outside hood helps, and it's worth doing. The rest of the run, especially where it bends or passes through a wall, needs a brush and rod system built for the job, and a contractor will have that.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than they used to, or that come out hot instead of dry, are the clearest sign. Check the outside vent hood while the dryer runs. If the flap barely moves or air is weak at the hood, the duct is restricted. A burning smell, a dryer that shuts off mid-cycle, or lint collecting around the door seal are also signs, and none of those should be ignored.
