Cold air in the vent gives lint somewhere to stick
Your dryer pushes warm, damp air out through the vent. On a night near 28°F, which is normal here from December through February, that air cools fast once it hits the metal duct. The moisture in it beads up on the walls of the vent, and lint sticks to the damp spots instead of blowing on through to the outside.
Layer by layer, that buildup narrows the path the air has to travel. The dryer has to push harder to move the same amount of air, and the exhaust that does get through carries heat and moisture back into the duct instead of out of the house.

- How often should a dryer vent be cleaned?
- A contractor can tell you based on how the vent is run in your house, but once a year is a reasonable starting point for most homes. A longer vent run, or one with several bends before it reaches outside, collects lint faster and may need attention more often. If your dryer is taking longer to dry loads than it used to, that is a sign to check it sooner rather than wait for the year mark.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first few feet of duct near the dryer yourself. A vacuum or a short brush reaches that part fine. Most of the lint that causes real blockages sits further down the duct, especially at bends and joints, and a short brush will not get there. A contractor uses a rod and brush long enough to clean the full run to the outside vent.
- What are the signs of a clogged dryer vent?
- Clothes that take longer than usual to dry, or come out hotter than normal, are the clearest sign. A burning smell during a cycle, a laundry room that feels warmer than it should, or lint collecting around the outside vent hood are other signs. If the outside vent flap barely moves or stays shut while the dryer runs, airflow is likely blocked somewhere in the duct.
