When an air conditioning line is damaged and losing all refrigerant other than the damage line what else should be replace?

When an air conditioning line is damaged and losing refrigerant, it's essential to replace not only the damaged line but also the receiver-drier or accumulator. This component filters the refrigerant and removes moisture, which can be contaminated after a leak. Additionally, the system should be evacuated and recharged with refrigerant, and any necessary seals or O-rings should also be checked and replaced to ensure optimal performance and prevent future leaks.
