This will depend on outside ambient temperature and the state of your compressor and system, but the low side should be somewhere around 30 psi and the high side should be around 150 psi. The low side is designed to open at about 20 psi and close around 45 psi if it is cycling the compressor clutch.

depends some on outside air temps and if you have a fan blowing across the condensor, rpms of the engine.... 30-38 on the low and 250 high
