Cold vents make lint stick
Your dryer pushes warm, damp air out through the vent. On a Thornton winter night, with temperatures averaging 16°F from December through February, that vent runs cold most of its length. The warm air hits the cold metal and cools fast, and the moisture in it settles on the walls of the duct. Lint sticks to that damp surface instead of blowing straight through to the outside.
Over a winter that runs from October through May, the buildup narrows the path the air has to take. A duct that is partly blocked makes the dryer work harder to push air through, and traps more heat and moisture inside the vent itself.

- How often should a dryer vent be cleaned?
- Once a year is the standard most manufacturers recommend. Lint builds up along the whole length of the vent, not just in the trap, and a clean line lets the dryer push heat and moisture all the way outside. If you notice drying times slipping before the year is up, have it checked sooner rather than waiting.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but most homes can't clear the whole line this way. Pull the dryer out, disconnect the vent, and clean the lint trap housing and the first few feet by hand or with a vent brush. The rest of the run is the problem, especially where it bends or passes through a wall or roof. That stretch needs a longer brush system or a vacuum built for the job, and a contractor will have both.
- What are the signs of a clogged dryer vent?
- Clothes taking longer than usual to dry is the first sign. The dryer or the clothes feeling hotter than normal is another. Check outside too. The vent hood flap should open and lint should flow out while the dryer runs. If it barely moves or nothing comes out, the line is blocked somewhere between the dryer and the hood. A burning smell or a musty smell during the cycle means it's time to have the vent checked.
