Arrived on-site to address a small rub out in the true low copper line soldered hole. First, I carefully inspected the area to identify the issue. Next, I pulled a thorough vacuum on the system to remove any air and moisture, ensuring optimal performance. After confirming the vacuum was complete, I charged the system with the appropriate refrigerant. Throughout the process, I maintained clear communication with the customer, explaining each step and addressing any concerns. The system was successfully restored, and the customer was satisfied with the restored functionality.
