What is a dryer booster fan — and why would a home need one?
A dryer booster fan is installed in some dryer vent systems to help move exhaust air through a longer or more complex vent run.
You may find one in homes where the laundry room is upstairs, the dryer vents through the roof, or the vent line travels a longer distance before reaching the exterior.
Not every home needs a booster fan. But when one is part of the dryer vent system, it should be working properly and maintained along with the rest of the vent line.
Some signs that the system may need attention include longer drying times, excessive heat, weak airflow at the exterior vent, or a booster fan that no longer sounds or operates the way it should.
