Cold vents give lint somewhere to stick
Your dryer pushes out warm, damp air, and that vent runs through a house where winter nights average 0°F from December through February. The air cools fast against those cold walls, and the moisture in it turns the lint damp instead of letting it blow straight outside. Damp lint sticks. It builds up in layers along the duct instead of clearing out with each load.
A vent that is closing up this way pushes more moist air back toward the dryer and the room around it. With heat needed in the house from September through June, that vent stays cold for most of the year, which means the buildup has nearly ten months to get worse before things dry out again.

- How often should a dryer vent be cleaned?
- Once a year is enough for most households. Lint builds up gradually along the duct, and a yearly cleaning clears it before it narrows the airway. A household that dries a lot of laundry, or has a long duct run to the outside vent hood, may need it checked more often.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but most homeowners can't clear the whole run. A vacuum and a brush kit will get lint out of the first few feet behind the dryer. The rest of the duct, especially where it bends or runs through a wall to the outside vent hood, needs a longer brush and someone who does this regularly to clean it without damaging the duct.
- What are the signs of a clogged dryer vent?
- Clothes taking longer to dry, or coming out hot to the touch instead of just warm, is the clearest sign. The outside of the dryer may feel warmer than usual, and you might notice a burning smell or less airflow at the outside vent hood when the dryer is running. A room that gets noticeably more humid during a drying cycle is also a sign air isn't moving through the duct the way it should.
