Step 1 of 3: Equipment
Cold vent walls catch the lint your dryer pushes out
Your dryer pushes out warm, damp air, and that air has to travel through a vent that runs through cold space before it reaches outside. Nights here average 9°F from December through February, so the metal stays cold for months at a time. Warm air cools fast against those walls, and the moisture that drops out gives lint something to stick to instead of blowing straight through.
Once lint builds up along the vent, airflow slows down. The dryer has to push harder to move air through a narrower path, and the damp lint further back can sit there instead of drying out and moving on.

- How often should a dryer vent be cleaned?
- Once a year is the standard rule, more often if you dry a lot of loads or the vent run is long. Lint builds up along the inside of the duct even when the lint trap looks clean, because the trap only catches what passes through it directly. A vent that cannot push air outside makes the dryer run longer to dry the same load, and that extra heat has nowhere to go but back into the duct.
- Can I clean my dryer vent myself?
- You can clean the first few feet near the dryer and the hood outside, but the rest of the run is hard to reach without the right brush and rod setup. Most vents bend at least once between the dryer and the outside wall, and lint collects right at those bends. A shop vac and a broom handle will not reach past the first turn, so if the vent is long or has more than one bend, a contractor with the proper rods can clear the whole length.
- What are the signs of a clogged dryer vent?
- Clothes that stay damp after a full cycle, a dryer that runs hot to the touch on the outside, and a musty smell in the laundry room are the clearest signs. Check the outside vent hood while the dryer runs. If you feel weak airflow or barely any at all, the duct is likely blocked somewhere along its length. A burning smell means stop the dryer and have the vent checked before running it again.
