In the low-pressure side of the system, R134a is a gas with low temperature and pressure, typically around 30 psi. In the high-pressure side, R134a is a high-temperature, high-pressure gas, usually around 250-350 psi. These two systems work together to transfer heat from the inside of the vehicle to the outside, providing cooling.
When a high pressure system moves into an area where a low pressure system already exists, it typically brings clearer skies, calmer weather, and cooler temperatures. The high pressure system will suppress the vertical movement of air associated with the low pressure system, leading to improved conditions.
It can have either a high or a low pressure system or neither depending on the weather it is experiencing at any given time.
The symbol for a high pressure system is typically represented in blue on weather maps.
a high pressure system moves clockwise, while a low one moves counter clockwise. high pressure systems move down and out, and low pressure systems move in and up.
The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.
R134a goes into the low pressure port
All r134a low pressure (suction) connections are the same size. All high pressure connections are the same size. The low and high connections do not interchange.
On a R134a system the low side service port is the smaller one.
20-30 on low side and 160-220 on high side depending on outside air temp.
If the pressures are always equal running, the compressor is bad and would need replaced
A high pressure systems has a high pressure center.
For a home air conditioning unit 35 psig low and 125 - 150 psig high (depending on outdoor temp) are desirable.
The high pressure system is warmer then the low pressure system . simple reason pressure is high when the molecules of gas are vibrating more violently then they do in normal routine ( vibrations of molecules can only be increased by increased temperature) hence if the pressure is high the temp will always be warmer then in low pressure area .

High side and low side refer to the pressure in the ac system. Ie The high side is the high pressure line and low side is the low pressure line.
