Hands cleaning a dryer vent duct with a brush behind a clothes dryer

The problem it solves

Your dryer takes two cycles to dry a load and you have never cleaned anything past the lint screen.

How to recognise restricted airflow, inspect the duct, clean it safely with the right tools, and know exactly when the job belongs to a professional.

Who it's for

Any homeowner or renter with a clothes dryer.

What you'll get out of it

  • Spot restricted airflow before it costs you a dryer
  • Clean the full duct run properly, not just the screen
  • Know the exact signs that mean stop and call a pro
  • A maintenance schedule you can keep

Warning signs of restricted airflow

Any one of these means the duct needs attention:

  • Clothes are still damp after a full cycle, or need a second cycle.
  • The dryer or the clothes are unusually hot at the end of a cycle.
  • The laundry room gets humid or smells musty while the dryer runs.
  • Little or no air movement at the exterior hood with the dryer running.
  • Lint visible around the hood, or the hood flap that never opens.
  • Cycle times have quietly got longer over the last year.

Airflow is the whole job. Everything a dryer does depends on moving hot, moist air out of the house. When that air cannot leave, the appliance works harder, runs hotter and wears out sooner — and hot lint in a restricted duct is a hazard you can simply remove.

Why it matters: Lint collects in the duct, not just the lint screen. A restricted vent makes the dryer run long, run hot and wear out early — and it is a fire hazard you can remove yourself in under an hour.
