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 causes high AC head pressure?
Bad Fan Motor This is actually the most common issue that causes high head pressure. You can have a bad fan motor due to a few different reasons. Your fan blades naturally wear down over time. The process of them wearing down can be expedited by debris finding its way into your air conditioner's outside unit.
What if my AC pressure is too high?
If your condenser has blockage or restriction of air flow, the high pressure side reading would be high while the low side readings would drop over time. To rectify this problem, you should remove and blockage and clear any debris. After removing the debris, check the readings again.

R134A Ac System Pressure - How To Spot The Issues!
What causes high side AC pressure too high?
In general, high pressure on both high and low pressure AC sides is typically caused by an obstruction in the evaporator. In some cases, this can be a simple debris that can be cleaned if removed, while in other cases, it could be due to internal damage.
What causes high pressure on low side of car AC?
AC Low Side Pressure Too High Causes If the air conditioning isn't blowing cold air and the low side pressure is too high, it could be caused by issues with the condenser fan. However, there's also the possibility that the system has gotten overcharged with too much refrigerant.
What causes high pressure in AC compressor?
High pressure occurs when the needle valve gets partially stuck open and goes directly into the compressor's crankcase. This causes both high low-side pressures and low high-side pressures. You should closely monitor whether or not the oil return line is above or below the ambient surrounding temperature.

How do you fix high AC pressure?
If your condenser has blockage or restriction of air flow, the high pressure side reading would be high while the low side readings would drop over time. To rectify this problem, you should remove and blockage and clear any debris. After removing the debris, check the readings again.

How To Fix Your Car Ac! (Over Pressurized System)
What happens when AC pressure is too high?
What happens when AC pressure is too high? High AC pressure can lead to a number of problems, such as decreased cooling capacity, freezing of the evaporator, and compressor failure. It can damage expensive parts like the compressor, so you definitely want to fix it as soon as possible.
What happens if AC compressor has too much pressure?
AC low side pressure getting too high means that the system can't generate the needed temperature to cool down the vehicle. This situation could be related to several possibilities. It could be something to do with the compressor or refrigerant added to charge the AC or even a leak in the system.
