Cold vent walls trap the lint your dryer pushes out
Your dryer pushes warm, damp air out through the vent, and in a Grafton winter that vent runs cold most of its length. The air cools fast against the metal, and the moisture in it lets lint stick to the walls instead of blowing on outside. Layer by layer, the vent narrows.
A narrowed vent has to fight the dryer's exhaust harder, and that heat and moisture have to go somewhere. Some backs up into the vent hose and the space around it. With winter nights averaging 1°F for months on end, a wet or blocked vent near an exterior wall is not a small problem to leave sitting.

- How often should a dryer vent be cleaned?
- Once a year is the standard, and here that's worth doing before the heating season starts in September, while the vent is still easy to get to. Lint builds up inside the vent run every time you dry a load, and a year's worth is enough to slow the airflow. Once the line is clogged, the dryer has to work harder and takes longer to dry each load.
- Can I clean my dryer vent myself?
- You can clean the first few feet from the back of the dryer and the outside vent hood yourself. What you can't reach is the rest of the duct run behind the wall, especially if it bends or runs any real distance to the outside. A contractor uses a rotating brush or vacuum line built to clear the whole length, not just the ends.
- What are the signs of a clogged dryer vent?
- Clothes that take more than one cycle to dry, a dryer that runs hot to the touch on the outside, and a musty smell in the laundry room are the main signs. Check the outside vent hood too. If the flap barely moves or you feel weak airflow when the dryer is running, lint is blocking the line somewhere between the dryer and the hood. A clogged vent also traps heat inside the dryer, which is worth taking seriously rather than living with.
