Cold vents trap the lint your dryer pushes out
Your dryer pushes warm, damp air through the vent, and for eight months a year that vent runs through a cold house. The air cools fast against those cold walls, and the moisture in it turns to dampness on the way out. Lint sticks to a damp wall far more than it does to a dry one, so the buildup collects faster than you would expect.
Once that lint builds up, the air has nowhere to go. It backs up into the dryer, the drying takes longer, and the exhaust that should be leaving your house stays in the duct instead.

- How often should a dryer vent be cleaned?
- Once a year is the standard most contractors work to. Lint builds up gradually inside the duct itself, not just in the lint trap, so there's no way to see it happening. A yearly cleaning catches it before airflow gets restricted enough to matter.
- Can I clean my dryer vent myself?
- You can clean the first few feet yourself, but that's usually not where the real buildup sits. A vacuum with a hose attachment can pull lint out near the dryer and near the outside hood. The rest of the run is harder to reach and harder to know if it's actually clear, which is why a contractor uses a brush and rod system that runs the full length of the duct.
- What are the signs of a clogged dryer vent?
- Clothes take more than one cycle to dry, or come out hot at the top and damp underneath. The outside vent hood flap barely opens or doesn't move much when the dryer runs. You notice a burning smell, or the dryer itself gets hot to the touch on the outside. Any of these means air isn't moving through the duct the way it should, and it's worth having someone check the full run rather than just the trap.
