Cold vents catch lint before it can blow clear
Your dryer pushes warm, damp air out through the vent. On a night near 34 degrees, that vent is cold, and the air cools fast on its way out. Lint that would blow clear in warm air sticks to the cooler, damp walls instead of making it outside.
Each load adds a little more. Over time the vent narrows and the dryer has to push harder to move the same air. Restricted airflow keeps heat and moisture in the line longer, which slows drying and can leave the vent damp between loads.

- How often should a dryer vent be cleaned?
- Once a year is the usual rule. Lint builds up along the whole vent run, not just in the trap you empty after every load, and a full year of loads is enough to narrow that path. If you notice clothes drying slower than they used to, do not wait for the year mark, have it checked sooner.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of duct behind the dryer yourself with a vent brush kit. That reaches further than your hand or a shop vacuum alone. Most vent runs bend through a wall or up through a roof before reaching outside, and a clog past those bends is hard to see or reach with a brush. If lint keeps building up after you clean what you can reach, a contractor with a longer rod and camera can clear the full line.
- What are the signs of a clogged dryer vent?
- Clothes that need a second cycle to dry, or come out hot to the touch instead of just warm, are usually the first sign. Check the outside vent hood while the dryer runs. If the flap barely moves or you feel weak airflow there, lint is blocking the line somewhere between the dryer and the hood. A burning smell, a dryer running hotter than usual, or lint collecting around the door seal are also signs the vent needs attention.
