Step 1 of 3: Equipment
Cold air turns lint into a clog
Every load sends warm, damp air down the vent and out through the wall. On a night near 11°F, that air cools fast the moment it hits the cold metal, and the lint riding along with it doesn't blow through anymore. It sticks to the damp walls of the duct instead of making it outside.
That buildup narrows the vent a little more with each load. Air that should rush out the hood starts backing up into the duct, and the dryer has to push harder to move it.
- 11°F

- How often should a dryer vent be cleaned?
- Once a year for most households. If you run loads almost every day, or if you notice towels and jeans taking longer to dry than they used to, check it sooner. A dryer that vents outside through a long duct run is worth checking on the same yearly schedule regardless of season.
- Can I clean my dryer vent myself?
- You can clear the lint trap and the first few feet of duct behind the dryer, but that is not the same as cleaning the vent. A vacuum reaches only so far, and lint tends to pack tight further down the line and at the hood outside. A contractor uses a brush and rod system built to clean the full length, including the hood.
- What are the signs of a clogged dryer vent?
- Clothes that take two cycles to dry, a dryer that runs hot to the touch, or a burning smell partway through a load. Check the outside vent hood too. If the flap barely moves when the dryer is running, air isn't getting through like it should, and a blocked vent traps heat inside the dryer instead of pushing it outside.
