Dirty coils
When dust and dirty oil keep blocking the compressor, the heat does not release properly and blocks the whole system, which causes the compressor to stop working and lock up the clutch. It can also overheat the engine.
Blocked suction lines
When the refrigerant lines are not working correctly, they will not let the heat be released. It causes the AC to heat up and will not provide cool air. If you cannot fix this problem, it will lead to damage to the whole system, and it will end up making the compressor a waste.

The proper lubricant will prevent this issue and save you a lot of money. If you are not using enough oil, the engine will decrease its value, and the compressor will release hot air.
Excessive refrigerant
if an unprofessional person fills up too much refrigerant in the compressor, it will also destroy its capability and ruin the vehicle. T will leave you with the option of replacing the compressor.
Low refrigerant
