Cold makes the lint stick
Your dryer pushes out warm, damp air every time it runs. Once that air hits the cold vent run, it cools fast, and the moisture in it beads up on the walls of the duct. Lint sticks to a damp surface a lot better than a dry one. Winter nights here average 16°F, so the vent stays cold most of the time your dryer is working.
That buildup narrows the duct and slows the air trying to get out. A dryer that has to push exhaust through a partly blocked vent runs hotter and takes longer to dry a load. Clearing the vent is what keeps that path open.

- How often should a dryer vent be cleaned?
- Once a year is the standard rule. Lint builds up inside the duct even if you clean the lint trap every load, because a portion of it always gets past the screen. Homes with a longer vent run or more than one bend need it checked more often, since lint has more surface to catch on.
- Can I clean my dryer vent myself?
- You can clean the part you can reach, but that's usually not the whole vent. A brush kit run from the dryer end or the outside vent hood clears a few feet of straight duct well enough. What it misses is lint packed at a bend, or sitting deep in a long run, and that's where clogs usually build. A contractor uses a longer rod system and can check the full length, including the vent hood, to make sure the whole thing is clear.
- What are the signs of a clogged dryer vent?
- Clothes take longer to dry, or come out hot to the touch even when they still feel damp. The outside of the dryer or the door itself may feel warm during a cycle. Check the vent hood outside while the dryer runs. Weak airflow there, or almost none, means lint is blocking the duct somewhere between the dryer and the wall. A burning smell during drying is a clear sign to stop the dryer and have the vent checked.
