Many conditions could apply here theres absolutely no set point pressure for 410a r22 or anything else.
High head pressure often indicates insufficient condensing effect which could be a dirty condensing coil slowed or disabled condensing fan or too high a condenser water temperature if a water-cooled system. I then found the pressure at around 45 psi on the suction and 185psi on the head. 11Discharge pressure also called high side pressure or head pressure is the pressure generated on the output side of a gas compressor in a refrigeration or air conditioning system. Leaky oil separator return line. Experts suggest using an IR heat gun or similar tempeature measuring tool to check the tempeature of the refrigerant line on each side of the valve. High head low suction 310 isnt high unless the outdoor temp is 70F which probably isnt the case.
