Cold vents make lint stick
Your dryer pushes out warm, damp air every load. On a winter night in Lewiston, that air hits a vent that has been sitting in 26°F cold, and it cools fast. The moisture in it has nowhere to go but the walls of the vent, and lint sticks to a damp wall a lot easier than a dry one.
That buildup narrows the vent a little at a time. Air moves slower, so the dryer takes longer to dry a load and runs hotter doing it. A vent that stays packed with lint is also a fire risk, since lint is what catches.

- How often should a dryer vent be cleaned?
- Once a year is the general rule for most households. If you run the dryer almost daily, or if the vent run is long or has several turns, check it more often than that. Lint builds up along the inside of the duct even when the lint trap looks clean, and it narrows the path the air needs to escape.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but most homes have a vent run you cannot see all the way through. A vacuum at the wall opening only pulls out what is near the end, not lint sitting further down the duct or packed at the outside vent hood. A full cleaning uses a brush or rod run the whole length of the duct, from the dryer to the outside wall.
- What are the signs of a clogged dryer vent?
- Clothes taking longer than usual to dry, or coming out hot instead of just warm, is the first sign. You may also notice the outside of the dryer getting hot to the touch, a burnt smell during the cycle, or very little air coming out at the vent hood outside when the dryer is running. Lint gathering around the lint trap door or the outside vent opening is another sign worth checking.
