High Head Pressure. High head pressure is typically accompanied by a low suction pressure. This combination can be indicative of restricted refrigerant. Essentially, this means that air and vaporized water travel through your HVAC’s evaporator until they get to the top of the compressor, where it remains because it will not condense.You are showing low head. Look at it this way. If everything is working properly you would have 8°-12° SC and 10°-20° SH. So lets look at just the SH side first. …Connecting the low pressure side to the suction side of the compressor helps in sucking out the excess pressure from low side AC. c. Close the Service Valve Before Releasing Pressure.
