Dryer exhaust vents eliminate heat, wetness and lint from your house. The lint that manages to get away the lint screen should wind up outdoors, through your dryer vent; unfortunately, many of it winds up caught in the clothes dryer duct. Lint accumulation limits air flow needed for the dryer to perform its job. As the clothes dryer labors to dry your laundry, it consumes more energy. Badly maintained dryer vent systems can result in investing an added $18– 24 per month not to point out repair service expenses when the appliance breaks down.
