What happens if you put too much R134a?
The problems with too much refrigerant A refrigerant overcharge alters the pressure inside the air conditioner and puts the compressor in danger. The Compressor: Excess refrigerant creates a danger called slugging. This is when extra refrigerant floods into the piston cylinders of the compressor when in a liquid state.
What does high pressure on low side mean?
If The Low Side Pressure Is High And The High Side Pressure Is Low… It could also be related to the AC pressure switch, the expansion valve, the evaporator, or the dryer. There could also be a leak in the AC system. The AC pressure switch regulates the flow of refrigerant through the compressor.
What are normal pressures for R134a?
What are the Normal Operating Pressures for R134a? The pressure for an ordinarily operating R134a is between 22 and 57 pounds per square inch (PSI).
Can R134A be charged as a vapor?
That’s a good sign. If you added it slowly enough, it would be mostly vapor before reaching the compressor.

R134A…… The blends like R401A, R409A, R410A and all in the 400 series of refrigerants must be charges as a liquid.
Do you charge 134a as a gas or liquid?
If you have a set of gauges, you can safely charge liquid into the low side. Just keep the low side gauge below 40 PSI while you charge. This will make the freon boil inside the charging line, it will be a gas by the time it enters the compressor.
