Before photos show the LG dryer, the foil transition hose and wall connection, and a roof termination heavily restricted by compacted lint. Hygienic Air accessed the appliance-side connection and the roof outlet, using service air lines to dislodge material from the exhaust route. A large compacted lint mass was removed during the work. Later photographs show the accessible roof outlet substantially open, an interior duct passage with only scattered small deposits, and the removable lint screen with open mesh. Removing this buildup reduces combustible material and exhaust restriction; the photo record does not claim measured airflow or a change in drying time.
