The Homeowner's Dryer Vent Maintenance Checklist
You don't need to be a technician to keep your dryer running safely. A few minutes every month and a professional cleaning once a year will keep the appliance efficient and your home protected. Here's the exact checklist we give our customers.
Every load
Clean the lint screen before you start the load, not after.
Give the screen a quick look for tears — a torn screen lets far more lint into the vent.
Check that the door seal is clean.
Every month
Wipe the moisture sensor bars inside the drum with a little rubbing alcohol — fabric softener residue makes them read wrong.
Look behind the dryer for lint on the wall or floor.
Walk outside and watch the vent hood while the dryer is running. Flap moving freely = good.
Every quarter
Pull the dryer out and vacuum around and under it.
Inspect the flexible transition duct from the back of the dryer to the wall. Kinks, crushed sections, and foil damage all need to be addressed.
Wash the lint screen in warm soapy water to remove dryer-sheet buildup.
Every year
Have the full vent line professionally cleaned and airflow-tested.
Replace the flexible transition duct if it's foil or plastic — semi-rigid metal is far safer.
Test smoke and carbon monoxide detectors on the same level as the dryer.
Key takeaways
- Lint screen every load, no exceptions.
- Outside vent-flap check is a 30-second monthly habit.
- Once-a-year professional service handles what you can't see.
