What happens if AC pressure is too high?
High pressure inside the ​condenser fan can causes the aluminium to distort and evaporator coils to leak. The cost of repair and replacement of compressor is high (about $450 plus $700 labor - price fluctuates greatly depending on car) as the dash might need to be removed for repair.
What causes high pressure on AC system?
Overcharging of refrigerant, liquid slugging of the compressor, oil contamination and other sources can damage compressor valves. Refrigerant overcharging will show up as high head pressure, normal suction line pressure, normal superheat, high sub-cooling.

What would cause AC pressure to be high?
Overcharging the system and leaks are some common reasons for AC issues. However, other issues could be: loose wiring, slipping belt, low or old oil in system, and the use of wrong compressor lubricant can cause issues with your coolant system.
What issues could cause excessively high condenser head pressure?
- Overcharging of the refrigerant in the system. - Operating the system at high range than the specified limit. - Malfunctioning of the condenser fan motor. - The system is charged with the impurities of non condensing gases. - The condenser coil is not cleaned well. - Refrigeration device plugged.

What are symptoms of overcharged AC?
The likely symptoms of an overcharged AC are poor cooling, no air coming out of the wents, weird noises from the engine bay, and check engine light turning on. Because the AC coolant is toxic, fixing an overcharged AC is a job for a professional AC mechanic.

What happens if AC system is overcharged?
Having too much refrigerant in your AC can damage the compressor. This can happen because the excess refrigerant will likely collect inside the compressor and cause subcooling, wherein temperatures are below normal. Furthermore, the extra refrigerant can flood the compressor and damage its mechanical parts.
