"Takes forever to dry — three cycles for one load"
Arts District apartment — the dryer vent ran through the wall and out the ceiling, an original 1960s installation. Lint had accumulated in a 90-degree elbow about 6 feet in, blocking roughly 70% of the airflow. Cleared the blockage, tested airflow at the exterior vent cap (was barely moving), replaced the thermal fuse that had tripped from the heat. Single cycle drying time from first test after: 42 minutes. The tenant mentioned their electricity bill had been climbing for months — that tracks with a restricted vent.
