Cold vents make lint stick
Your dryer pushes out warm, damp air every time it runs. From October through May, that air is moving through a vent that sits in a cold house or a cold attic space, with nights averaging 24°F in the coldest months. The warm air cools fast once it hits that metal, and the moisture in it settles on the walls of the vent. Lint sticks to a damp surface far better than a dry one.
Over time that buildup narrows the vent. Air has a harder time getting out, so moisture and heat that should leave the house stay in the line instead. A vent packed with damp lint is also the kind that keeps a dryer running longer than it should to get clothes dry.

- How often should a dryer vent be cleaned?
- Once a year for most households. If the dryer is used heavily, or the vent run is long with a lot of bends, it is worth checking more often than that. Lint builds up along the whole length of the duct, not just at the ends, so a vent that looks clear at the wall hood can still be packed further in.
- Can I clean my dryer vent myself?
- You can handle the part you can reach, but most of the vent is not the part you can reach. A vacuum at the wall hood and a brush a few feet into the duct will clear surface lint, but the rest of the run, especially anywhere it bends or passes through a wall, needs a rod system or a contractor with the right tools to clear it fully. A vent that is only partly cleaned still restricts airflow the same way a fully clogged one does.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that runs hot to the touch on top, and a burning smell are the main ones. Check the outside vent hood too. If the flap barely moves or doesn't open all the way when the dryer runs, air isn't getting out and lint is building up somewhere in the line. A vent clogged enough to restrict airflow is also a fire risk, so any of these signs are worth acting on rather than waiting.
