Your dryer vent is easy to forget about. It sits behind the machine and runs through a wall or roof, out of sight. But a clogged dryer vent is one of the most common causes of home dryer fires, and it can also make every load take longer and cost more to dry. Here are the warning signs that your dryer vent needs attention.
1. Clothes Take Longer to Dry
If a normal load now needs two cycles, restricted airflow is a likely cause. When lint builds up in the vent, hot, moist air cannot escape, so the clothes stay damp.
2. The Dryer or Laundry Room Feels Hot
When hot air can’t leave through the vent, heat builds up in the dryer and the room around it. If the top of the dryer or the clothes feel unusually hot, it is worth checking the vent.
3. A Burning Smell
A burning odor while the dryer runs can mean lint is getting too hot. Stop using the dryer and have the vent inspected before running it again.

4. Lint Around the Dryer or Outside Vent
Lint collecting behind the dryer, around the door, or at the outside vent hood is a sign the system is not moving air properly.
5. The Outside Vent Flap Doesn’t Open
While the dryer runs, the flap on the outside vent should open from the airflow. If it barely moves, something is blocking the air on its way out.
6. It Has Been More Than a Year
Even without obvious symptoms, many homes benefit from having the dryer vent cleaned about once a year. Large families, frequent laundry and long vent runs may need cleaning more often.
7. Birds, Nests or Debris at the Vent
Outside vents can attract nesting birds and collect leaves or debris, which can block airflow completely.
Why the Lint Screen Isn’t Enough
Cleaning the lint screen after every load is important, but it does not catch everything. Fine lint passes through the screen and slowly collects inside the duct, especially at bends and long horizontal runs. Only a full vent cleaning removes that hidden buildup.
What a Professional Dryer Vent Cleaning Includes
A technician inspects the vent path, uses rotary brushes and vacuum equipment to clear lint from the full length of the duct, checks the outside vent hood, and confirms that air is flowing properly when the dryer runs. Learn more on our dryer vent cleaning service page.
Simple Dryer Safety Tips
- Clean the lint screen before or after every load.
- Don’t run the dryer when you leave home or go to sleep.
- Avoid overloading the dryer.
- Keep the area around the dryer free of clutter and flammable items.
- Use rigid or semi-rigid metal ducting rather than plastic or foil.

Frequently Asked Questions
How often should I clean my dryer vent?
About once a year for most homes, and more often if you do a lot of laundry or have a long vent run.
Can I clean my dryer vent myself?
You can clean the lint screen and the area behind the dryer, but a full vent cleaning requires tools that reach the entire duct, including bends and the section inside the wall.
Does a clean dryer vent save money?
When air flows freely, clothes dry faster, so the dryer runs for less time on each load.
