Dryer vent cleaning that takes the fire risk seriously.
Lint builds up inside the vent run, the dryer works harder, and the fire risk climbs. Cleaning the vent path brings the airflow back.
The screen only catches part of it.
The lint screen on a dryer catches what it can, and the rest travels into the vent. Over time that lint settles at every bend and at the outside termination, the airflow drops, and the dryer runs longer and hotter to do the same load. Clothes that take two cycles, a dryer that is hot to the touch, or a burning smell are the usual warnings, and they tend to arrive before anyone thinks to check the vent.
The reason it matters is fire. Lint is dry and fine, the duct gets hot, and a restricted vent is one of the more common causes of a dryer fire. Long Island houses add their own complications: long vent runs to an outside wall, terminations buried in foundation plantings, and seasonal homes where the dryer sat unused and the vent uninspected for months.
Cleaning clears the full run from the back of the dryer to the outside cap, not just the first foot of hose. Afterward the airflow should be noticeably stronger and the loads should dry in a single cycle again.
Signs the vent needs attention.
- Clothes take longer to dry than they used to, or need a second cycle.
- The dryer cabinet or the laundry room gets unusually hot during a cycle.
- You smell something hot or burning when the dryer runs.
- The outside flap does not open while drying, or it is clogged, screened over, or buried in shrubs.
- The vent run is long, has several bends, or you do not know when it was last cleaned.
