Step 1 of 3: Equipment
Cold vents trap the lint your dryer sends out
Your dryer pushes out warm, damp air every time it runs. Once that air hits the vent, it starts to cool, and Madison County winter nights average 37°F from December through February. Damp air moving through a cold vent doesn't stay damp for long. It cools fast, and lint sticks to the wet walls of the duct instead of blowing out the hood.
That buildup narrows the vent a little more each time you dry a load. Air backs up, the dryer runs longer to do the same job, and the lint sitting in the duct is exactly what a dryer fire needs.

- How often should a dryer vent be cleaned?
- Once a year is right for most homes. Lint builds up along the vent run every time you dry a load, and a year's worth is usually enough to start slowing the airflow. If you dry a lot of laundry, run a heat pump dryer, or your vent run is long with several bends, check it sooner.
- Can I clean my dryer vent myself?
- You can clean the lint trap and the first foot or two behind the dryer yourself, but that only reaches part of the vent. The rest of the run goes through the wall and often up or across framing before it reaches the outside hood, and that part needs a brush system built for the full length. If your vent has more than one bend or runs more than a few feet, a contractor has the equipment to clear it without damaging the ductwork.
- 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, and a burning smell during the cycle are the clearest 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 path. A weaker sign is more lint than usual collecting in the trap or around the door seal.
