Cold vents catch more lint than warm ones
Every load sends warm, damp air out through the vent. On a winter night here, with temperatures down around 30°F, that vent is cold from end to end. The warm air cools fast against the cold metal, and the moisture in it settles on the walls of the duct. Lint sticks to that damp surface instead of riding out with the airflow.
Over a heating season that runs October through April, that buildup adds up. A vent that is narrowed by lint pushes moist air out slower, and some of it works back into the house instead.

- How often should a dryer vent be cleaned?
- Once a year for most households. Lint builds up inside the vent pipe even when you clean the lint trap every load, and a partly blocked vent makes the dryer run longer and hotter than it should. A contractor can also tell you if your specific setup, like a long vent run or one with several bends, needs more frequent attention.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but most homes can't get the whole vent run cleared without the right tools. A vent brush kit will clean the first few feet from the back of the dryer. The rest of the run, especially where it bends or where it exits the wall or roof, needs a longer rod system or a shop vacuum with an extension to reach the lint sitting further down the line. If your vent run is long or has several turns, a contractor can clean the full length and check that the vent hood outside is opening and closing the way it should.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, or come out hot to the touch instead of just warm, are the clearest sign. Others include a burning smell while the dryer runs, the outside of the dryer feeling hot, and little to no airflow at the vent hood outside the house when the dryer is on. Lint gathering around the lint trap door or on the floor behind the dryer is also a sign air isn't moving through the vent the way it should.
