Cold vent walls trap the lint your dryer pushes out
Your dryer pushes out warm, damp air every time it runs. That air has to travel through a vent that sits inside a wall or attic that is cold most of the year here. Sisseton winter nights average 6°F from December through February, so the metal walls of the vent are cold too. Warm air hits that cold metal and cools fast, and the moisture in it has somewhere to go. Lint sticks to a damp surface much easier than a dry one, and it builds up layer by layer along the duct.
Once lint packs into the vent, the dryer has to push air through a narrower path. That means longer drying times, more heat staying inside the machine, and a higher chance of a fire starting in a space you cannot see.

- How often should a dryer vent be cleaned?
- Once a year is the standard, more often if you run loads daily or have a long vent run. Lint builds up along the inside of the duct even when the lint trap is clean, and it narrows the path air needs to escape. With heating needed here from September through May, a dryer stuck running long cycles is one more strain on a house already working hard most of the year.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but most homes have vent runs longer than a homeowner brush kit covers. Pull the dryer out, detach the flexible hose, and clean it and the lint trap housing by hand. If the vent runs a long distance to an outside wall or has bends in it, the far sections need a contractor with the right length of rod and a vent brush.
- What are the signs of a clogged dryer vent?
- Clothes taking longer than one cycle to dry is the clearest sign. Others include the outside of the dryer feeling hot to the touch, a burning smell during the cycle, and the exterior vent hood flap not opening much when the dryer runs. Weak airflow at the vent hood outside, checked while the dryer is on, tells you the same thing directly.
