During air conditioning mode, the pressure on the vapor line of an R-410A system will be somewhere between 102 to 145 PSIG. Suction Pressure/EVAP DTD Rule of Thumb Another common old-school rule of thumb is that suction pressure should be close to the outdoor temperature in an R22 system. However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20°-25° suction saturation below outdoor ambient.After the suction line has been strapped to the joist or rafter at 8’ (2.4 m) intervals, strap the liquid line to the suction line. 8’ (2.4 m) Metal Sleeve Wire Tie (around suction line only) Floor Joist or Roof Rafter Tape or Wire Tie Tape or Wire Tie If hanging line set from a joist or rafter, use metal strapping or heavy nylon wire tires

The main reasons your compressor will have simultaneously low head pressure and high suction pressure is due to: Bad or leaky compressor valves. Worn compressor piston rings. Leaky oil separator return line. Your compressor valves may become inefficient due to poor sealing from dirt and debris deposits.The liquid line pressure at 108°F saturation temperature is 356.5 PSIG. This screenshot of the Ref Tools app shows the liquid line pressure of R410A at saturation at 108°F. Notice how the slider has been set to BUBBLE point (inside the orange box). Vapor Line Pressure: Again, we already have the return air temp data, which is 74°F.

An R-22 evaporator running at 40F saturation temperature will have a corresponding pressure of 68.5 psig. Should the suction pressure drop below 57 psig, the coil temperature will drop below 32F causing moisture in the air to freeze on it (see Figure 4) causing no end of trouble.

You eliminated every other cause for a high low pressure (Air flow, refrigerant, compressor txv). I would try touching and observing the piping for any sudden change in temperature. Student here, so take this with a grain of salt. 2. the heat content of the return air (including the sensible temperature) drops, the saturated suction temperature will drop, resulting in a drop in suction pressure. As the suction pressure falls to 120psig the APR Control will begin to open and attempt to stabilize the system suction pressure at approximately 120psig.
