SafetyHow Often Should You Really Clean Your Dryer Vent?
Most homeowners clean the lint trap after every load and assume that's enough. It isn't. The lint trap only catches a portion of what your dryer produces — the rest travels down the duct and slowly builds up along the way, out of sight.
Why the lint trap isn't the whole story
Even a lint trap cleaned after every single load still lets a small amount of lint pass through. Over hundreds of loads, that adds up inside the duct itself — especially at bends, joints, and wherever the vent run is longer than a straight shot to the outside wall.
Warning signs your vent needs cleaning now
- Clothes take noticeably longer to dry than they used to
- The dryer feels hot to the touch on the outside during a cycle
- You smell a burning odor during use
- You see lint collecting around the exterior vent cap
- It's been more than a year since the last full cleaning
- The laundry room has a persistent musty smell
If you smell burning, stop and act
A mild lint smell is normal. A burning smell is not — turn the dryer off, unplug it if it's safe to do so, and have the vent inspected before running it again.
Why this matters more than it seems
A restricted vent doesn't just slow down laundry day. It forces the dryer to run hotter and longer than it's designed to, which strains internal components and shortens the appliance's lifespan. More importantly, national fire safety data consistently points to lint buildup and restricted airflow as a leading cause behind thousands of home dryer fires every year.
Factors that mean you should clean more often
- A longer vent run, especially one with multiple bends or turns
- A household that does laundry daily or has a larger family
- Pets that shed, which adds extra lint and fur to the load
- A vent that runs through the attic or exits through the roof
Overdue for a vent cleaning?
Think of dryer vent cleaning the same way you'd think of changing an air filter — it's easy to put off precisely because nothing looks wrong from the outside. A once-a-year cleaning is a small step that lowers fire risk, extends the dryer's life, and usually shortens drying time right away.
When did you last have your vent cleaned?
If you're not sure, that's usually a sign it's time. Most cleanings take under an hour.
