Once the repair is complete, the system undergoes a vacuum process to eliminate moisture and air, followed by a precise refrigerant recharge to manufacturer specifications. The technician then performs a pressure test and leak detection to ensure the repair is secure and the system is operating efficiently. Proper AC copper pipe repair must be done by certified professionals, as mishandling refrigerants or poor-quality repairs can lead to system failure or safety risks. Routine maintenance and timely repairs help prolong the life of the AC system and keep it running at peak performance.
