* Direct impact: If a rock strikes the compressor with enough force, it can crack or break the housing, causing the compressor to leak refrigerant and fail.
* Damage to the condenser: The condenser is a heat exchanger that helps to dissipate heat from the refrigerant. If a rock damages the condenser, it can reduce the efficiency of the AC system and eventually cause the compressor to overheat and fail.
* Damage to the refrigerant lines: The refrigerant lines carry refrigerant between the compressor and the condenser. If a rock damages a refrigerant line, it can cause the refrigerant to leak out and the AC system to fail.
* Damage to the AC clutch: The AC clutch is a magnetic clutch that engages and disengages the compressor. If a rock damages the AC clutch, it can prevent the compressor from engaging and the AC system will not work.
