If the LOW gauge reading is less than this, the A/C system probably needs some additional refrigerant. The actual pressure readings will vary depending on the type of refrigerant (R-134a or R-1234yf) that is in your A/C system. The higher the GWP the more harm the refrigerant does to the climate. R-410A has a GWP of over two-thousand whereas R-32 has a GWP of only six-hundred and seventy-five. While R-32 isn’t perfect it is a lot better then R-410A.
