Cold vents make the lint stick faster
Every load pushes warm, damp air out through the vent. From October through May, that vent is running through a cold house, and on a 19°F night the pipe walls are cold enough that the moisture in the exhaust condenses before it clears the house. Lint sticks to a damp wall instead of blowing out the hood, and the buildup grows from the inside where you can't see it.
A vent that's losing airflow makes the dryer run longer to dry the same load, and pushes more warm, moist air into the space around the duct. Left alone, that's a lint clog sitting in a house, right where you don't want one.

- How often should a dryer vent be cleaned?
- Once a year is the standard rule, though a vent that runs long or has several bends traps more lint along the way and may need attention sooner. Clothes taking longer to dry than they used to is a sign not to wait for the year mark. A straight, short run to the outside wall stays clear longer than one that snakes through a wall or ceiling.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet behind the dryer yourself, but the full duct run is harder to reach. Most vents run several feet through a wall or ceiling to the outside, and lint can pack in anywhere along that path, not just near the machine. A shop vac and a brush kit handle the parts you can see, but a contractor has the rods to clear the whole line and check that the outside vent hood opens properly.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, a dryer that feels hot to the touch on the outside, and a burning smell when it runs are the main signs. Check the outside vent hood while the dryer is going. If you feel little or no airflow there, or the flap barely lifts, lint is likely blocking the line. A weak flow also means moist air is backing up into the duct instead of venting outside, which is worth fixing before it gets worse.
