When all of these components appear to work fine and the AC low side high, high side low problem persists, you may need to change the compressor to fix the unit. Similarly, the fan also has to spin when you turn the system on. Also, check if the compressor clutch engages and rotates the compressor when the AC is on. Use an Ohmmeter to find if it is giving the correct reading. The switch is located near the expansion valve. (Photo Source: hummerforums)īefore deciding to replace the compressor, other components that you may check are the pressure switch, expansion valve, and the compressor clutch. The same problem arises when the o-ring seal outside of the orifice tube wears out. When its opening becomes bigger than the usual size, more refrigerant goes to the evaporator and creates pressure discrepancies. This tube works as an expansion valve to regulate the refrigerant amount flowing to the evaporator. It could be an issue with the orifice tube too. It could also be a failed thermal bulb that is unable to pick up the temperature signals or the TXV stuck to the open position. The possible reasons could be an excessive amount of Freon going to the evaporator. But if you see the AC low side high, high side low, such as the low side is 100 and the high side is 150, there might be problems with any of the inner components. The pressure reading from the low side should be between 25 and 30 psi and the high side between 200 and 250 psi. A Safe and Secure Way to Flush AC System After Compressor FailureĪC Low Side High, High Side Low: Why Does This Happen?.On the other hand, there is possibly a huge leak when the pressure is zero. Readings higher than the chart indicate an overcharged system while lower readings confirm a low level of refrigerant and a possible leak. ![]() Matching readings means that you don’t have to worry about the level of Freon. Compare the pressure readings with the pressure chart. Check the ambient temperature and see if the pressures match the numbers on the pressure chart. To gauge the pressure, hook up a gauge set to the AC system and record the pressures of both low and high sides. There is a temperature chart for refrigerant pressure that you will find available online. You can measure the refrigerant’s pressure at a given temperature. In fact, the temperature is directly related to the system’s pressure. There are several constraints that cause this state. One symptom indicating a complication in the air conditioning is AC low side high, high side low pressure. There could be several causes leading to this condition including compressor issues, low-level of refrigerant, trouble with the heater or AC controls, and others. One typical issue is the unit not blowing cold air, which could be punishing in hot weather. The AC system in your car could go through all sorts of problems.
