How Often to Clean Your Dryer Vent
Dryer vent cleaning is one of those maintenance tasks that's easy to forget about until something goes wrong — and when it does go wrong, it's a bigger deal than most people expect. A clogged dryer vent is one of the leading causes of home dryer fires, and it also quietly drives up energy bills by making your dryer work harder than it should.
Why Vent Cleaning Matters
Every time you dry a load of laundry, lint travels through the vent duct along with the hot exhaust air. Some of it escapes outside, but a portion sticks to the inside of the duct over time. As that buildup grows, it restricts airflow, which forces your dryer to run longer and hotter to dry the same load — and that heat has nowhere to safely escape.
Recommended Cleaning Schedule
- Every load: Clean the lint trap/screen inside the dryer door — this takes seconds and should become a habit.
- Every 6 months: Have the full vent duct cleaned if you do laundry for a large household or run the dryer daily.
- Every 12 months: A full vent cleaning for average households is the minimum we recommend, even if you haven't noticed any problems yet.
- More often: If your vent run is long, has several bends, or vents up through the roof rather than straight out a wall, lint accumulates faster and cleanings should happen more frequently.
Signs Your Vent Is Clogged
- Clothes take two or more cycles to fully dry.
- The dryer feels unusually hot to the touch on the outside during a cycle.
- You notice a burning smell during drying.
- The laundry room feels noticeably more humid than usual after a cycle.
- Visible lint buildup around the outside vent opening.
DIY Lint Trap Cleaning vs. Professional Vent Cleaning
Cleaning the lint trap yourself is simple and should be done after every load. But the lint trap only catches what's near the door — it doesn't clean the full duct run behind the dryer and through the wall or roof. A professional vent cleaning uses specialized brushes and a vacuum system to clear the entire length of the duct, which isn't something a household vacuum can reach effectively.
Skip the guesswork and have the full duct professionally cleared.
