Water Leaks Around the Unit Water leaks come from a few common issues. The drain line may be blocked, the drain pan may be cracked, or the evaporator coil may be frozen. When the coil freezes, the ice melts and spills over the edge. A clogged drain line is the most frequent cause. Dirt, algae, and mold often build up inside the pipe. A technician will flush the drain line, clear the blockage, and clean the drain pan. If the evaporator coil is freezing, they check for low refrigerant or poor airflow. Once the cause is fixed, the leaking stops and the system runs safely again.
