The main idea is to follow a proper repair-and-recharge sequence that ensures the system is leak-free and properly charged once finished. Start by identifying and repairing the leak so the refrigerant stop leak is permanent. Then evacuate the system to remove air and moisture and any non-condensables that could affect performance or cause moisture-related damage. After obtaining the required vacuum, recharge the system to the specified amount so you know the charge is accurate for that appliance. Finally, perform leak checks again to confirm the repair is holding and no new leaks are present. Skipping the post-repair leak check or charging before repairing would leave leaks undiscovered or waste refrigerant and moisture, leading to improper operation and potential safety issues.
