Step 1 of 3: Equipment
Cold air turns lint into a wall inside your vent
Your dryer pushes out warm, damp air, and that air has to travel through metal duct sitting in cold space before it reaches outside. On a night near 23°F, that air cools fast once it hits the vent, and the moisture it's carrying turns to dampness on the inside walls. Lint sticks to a damp wall instead of blowing on through, and layer by layer it builds into a clog.
A clogged vent means the dryer is pushing air against a wall of lint instead of out of the house. That is what leaves clothes taking longer to dry, and it is what turns a dryer vent into a fire risk.

- How often should a dryer vent be cleaned?
- Once a year, at minimum. Lint builds up along the whole run, not just in the trap, and a full year of normal use is enough to narrow that path and slow the airflow. If you notice any of the warning signs sooner, don't wait for the year mark.
- Can I clean my dryer vent myself?
- You can clean the parts you can reach, but not the whole run. Pulling the dryer out and vacuuming the first few feet of duct, plus the outside vent hood, is worth doing on your own. The rest of the run, especially where it turns or passes through a wall, needs a rod and brush system built for the length of the duct, and a contractor will have the right one for the job.
- What are the signs of a clogged dryer vent?
- Clothes coming out hot but still damp is the clearest sign. Others include the outside vent hood flap barely moving when the dryer runs, a burning smell, the dryer running hotter or longer than it used to, and lint showing up around the door seal. Any one of these on its own is worth a look.
