Cold vents make lint stick
Your dryer pushes out warm, damp air, and that air has to travel through a vent that sits in a cold space most of the year. Burlington winter nights average 19°F from December through February, so the vent walls are cold too. When warm exhaust hits that cold metal, it cools fast, and the moisture in it makes the lint cling instead of blowing on through to the outside.
Over time that lint builds into a layer the airflow cannot push past. The vent narrows, the dryer takes longer to dry a load, and the exhaust that should be leaving the house has a harder time getting out.

- How often should a dryer vent be cleaned?
- Once a year is the standard rule for most dryer vents. Lint builds up inside the duct with every load, and it narrows the path air needs to escape. A vent with a long run or several turns to get outside is worth checking a little more closely, since lint has more surfaces to catch on along the way.
- Can I clean my dryer vent myself?
- You can clean the lint trap and reach a few feet into the duct yourself, but most homeowners cannot clear the whole vent. The duct usually runs through a wall or ceiling before it reaches the outside hood, and a rod-and-brush kit only goes so far around bends. A contractor uses a longer brush system built to clear the full run and check the outside hood at the same time.
- What are the signs of a clogged dryer vent?
- Clothes that need a second cycle to dry, a dryer that runs hot to the touch, and a burning smell are the main signs. Weak airflow at the outside vent hood while the dryer runs, or lint collecting around the hood flap instead of blowing clear, are also signs worth acting on. A blocked vent makes the dryer work harder than it should and raises the risk of a fire.
