Patching rust holes on condenser coils is a critical step in repairing a Freon leak. The process involves thoroughly cleaning the area around the hole to ensure proper adhesion of the sealant. A specialized sealant designed for use with refrigeration systems is then applied to cover the hole effectively, preventing further leakage of Freon. This repair is crucial for restoring the efficiency of the refrigerator and preventing future leaks. It’s important to use the correct materials and techniques to ensure a lasting repair.
