HVAC Game-Changer High Pressure vs. Low Pressure Port Optimization

the low pressure port is the one near the dryer. the high pressure is the port near the compressor. So I found out my AC was BADLY leaking out of the high pressure port and the O-ring for the low pressure switch was in bad shape when I pulled ... If the system is on and you have 85psi on the low side you may have too much Freon in the system. However, it is hard to predict what the system ... 250psi isn't too high. The a/c pressure switch turns off the compressor if the pressure is below 28psi or higher than 460psi. Some older posts by p_gill indicate 35-40 psi on the low side and 150-155 psi on the high side, but no reference back to a spec. Also when the compressor is running, the low pressure or suction side is the hose that is cold or has condensation on it. As Robroy mentioned, ... Typical pressures when running are 30-40 on the low and 200-250 on the high side. These pressures will change based on ambient temperature and ... The high pressure port on the hard lines is smaller than the low pressure port on the drier. I have an R134 gauge set, which seems to fit the low pressure port ... The 2006 A/C pressure switch is located in the high side refrigerant line, between the condensor and the expansion valve at the evaporator (in ... 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 ...
