Cold vents turn dryer lint into a damp mat
Your dryer pushes out warm, damp air every time it runs. From October through April, that air is moving through a vent that sits in cold space, and on a night near 26°F the metal cools fast. The moisture in the exhaust hits those cold walls and lint sticks to it instead of blowing through to the outside hood.
Over a winter that buildup narrows the vent, then blocks it. A blocked vent means the dryer has nowhere to push that hot, damp air, so it backs up into the duct and the room around it.

- How often should a dryer vent be cleaned?
- Once a year for most households. That's often enough to clear the lint that builds up in the duct over normal use. A contractor can tell you if your setup needs more frequent cleaning once they've seen the length and shape of the run.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of accessible ducting yourself. What you can't reach is the rest of the run behind the wall and out to the vent hood, especially if it has bends or covers real distance. A clogged vent that far in needs a brush and rod system built for the job, which is why most people call a contractor for a full cleaning rather than a partial one.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry is the biggest sign. Others include the outside of the dryer feeling hot to the touch, a burning smell during a cycle, and little to no airflow felt at the vent hood outside when the dryer is running. If you notice any of these, it's worth having the vent checked before running more loads.
