What does low head pressure mean?
Low head pressure may occur simulataneously with high pressure on the suction side of an air conditioner, heat pump or refrigeration system compressor system. If the system is continuing to cool it may be doing so at reduced capacity, observed as a loss of up to ten degrees of temperature drop across the coil.
Can R134a and R22 be mixed?
In conclusion, do not mix R-22 with R-134a refrigerants, you will ruin the charge, and possibly seriously damage or destroy your A/C system.
What happens when you take R-134a out of the compressor?
The car no longer cycled the compressor rapidly after taking some R-134a out of the system and it cools very well. So, the car only needed a bit more than 1/2 a container of 12-ounce freon and it was working like a champ!
What should the PSI be on a R134a?
The pressure for an ordinarily operating R134a is between 22 and 57 pounds per square inch (PSI). Remember, there are two sides to the chart; we have the low and the high. Therefore in a normal R134a, the low-pressure side is 90 degrees or less, and the PSI should be close to 30. Having gone through all the above details, you are still wondering,
Which is the low side of the R134a?
Remember, there are two sides to the chart; we have the low and the high. Therefore in a normal R134a, the low-pressure side is 90 degrees or less, and the PSI should be close to 30. Why Is my Low Side AC Pressure High?
What does a low compressor pressure reading mean?
AC Compressor Pressure Readings & their Meaning Low Pressure Gauge High Pressure Gauge Inference/Action Required In range In range AC is working properly Low Low Add refrigerant Low High Need service, possibly blockage of the e High Low Need service, possibly faulty compressor

What should the pressure be on an AC compressor?
Note: The most ideal pressure readings are around 150 high and 30 low. Warning: Remember, venting 134a refrigerant into our atmosphere is illegal and bad for our environment. The following table presents the possible inferences and the actions that can be taken, based on the level of pressure registered by the high and low pressure gauges:
