Asking because we at the shop charge through the high side port, but it takes way longer and sometimes the machine can't even pump it well ... Normal AC Pressures Using R-134A · At a temperature of around 65°F (24°C), the low-side pressure typically ranges from 25 to 35 psi. At an ... The R-134a and R-1234yf pressure charts are for guidance when using A/C Pro® recharge products and gauges. ... Standard Low Side Pressure Range PSI, Standard High ... Learn the 4 main conditions that will cause your vehicle's A/C pressure to have low side pressure that is high and high side pressure that ...

The compressor initially began pulling the low side down to 30 psi, then began to climb in pressure and would cycle off around 70 psi. After the compressor stops, pressure from the high side bleeds over to the low side via the TXV, or orifice tube. Pressure on the high side ... As noted, you need some real gages. I suspect your high reading is while the compressor is cycled off, in which case high side and low side will ...
