Cold vents turn damp lint into a blockage
Your dryer pushes out warm, damp air every time it runs. Once that air hits the vent, it starts giving up heat to the metal around it, and this house sits somewhere winter nights average 23°F from December through February. The cooled air can't hold its moisture, so it lets go inside the vent. Lint sticks to the wet walls instead of blowing straight through to the outside.
That buildup narrows the path a little more each time the dryer runs. Air backs up instead of venting out, and the dryer has to push against it. Left alone, that's a blocked vent full of damp lint, right where a stray spark can catch.

- How often should a dryer vent be cleaned?
- Once a year for most households. A household that dries more loads, like one with kids or a larger family, fills the duct with lint faster and may need it checked more often. A vent that runs long or has several turns before it reaches outside also fills faster than a short, straight one, so that's worth a look between cleanings.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of duct behind the dryer yourself. A vent brush kit reaches further than a vacuum alone and does a better job on the bends. The part most people can't reach is the vent hood outside and any long run through the attic or between floors, and that's where lint tends to pack in tightest. A contractor has the length of rod and camera gear to clear the whole run and check that the vent hood flap opens freely.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than one cycle to dry, or that come out hot to the touch, are the clearest sign. Others include a burning smell while the dryer runs, the outside of the dryer feeling hot, and little to no airflow at the vent hood when the dryer is on. Lint collecting around the lint trap door or showing up outside the vent hood also points to a blockage building up in the duct.
