Cold air in the vent is what turns lint into a clog
Your dryer pushes out warm, damp air every load. Once that air hits the cold vent run, it cools fast, and the moisture in it settles on the walls of the duct. Lint sticks to damp metal a lot easier than it sticks to dry metal, so the buildup starts closer to the dryer and works its way down the line.
With winter nights here averaging 27°F from December through February, that vent stays cold for most of the run. A vent that's narrowing with lint pushes moist air out slower, which means it stays wet longer and traps even more on the way out. Left alone, that's a stalled dryer, a hot exhaust with nowhere to go, and in the worst case, a fire hazard sitting inside the wall.

- How often should a dryer vent be cleaned?
- Once a year is the standard the trade works from. Lint builds up along the length of the vent even when you clean the lint screen before every load, because the screen only catches part of it. If your vent run is long or has several bends, it can fill in faster than a straight, short run would.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but that is usually not the whole job. Pulling the dryer out and clearing the first few feet of duct helps, and a vent brush kit will get you further in. What most people can't do is reach the full run to the exterior hood, especially where it passes through a wall or up through a roof, and that is where the worst buildup collects.
- What are the signs of a clogged dryer vent?
- Clothes that take more 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, the exterior vent hood flap barely moving or not opening when the dryer runs, and lint collecting around the hood outside. Any one of these on its own is worth checking, and a clogged vent is a fire risk, not just an inconvenience.
