Pressure that is too much lower or higher shows there is a problem. On a properly working system, high - side pressure will be about twice the ambient temperature, plus 50 PSI.Not much more to add, really. 0 PSI on R-12 is about -21 degrees. Depending on your target temperature, you will be very close to, if not below atmospheric on the low side. If you had to put more than half the charge in it, you probably have an obstruction at the metering device. Reply.

R-32 along with R-125 gets you that R-410A that is found in nearly every air conditioner today. However, in recent years there has been a push to slowly phase down R-410A. That is because of 410A's very high Global Warming Potential, or GWP.R22 gauge pressure is 10.9 bar or 158.2 psi. High side pressure typically varies by equipment and metering controls. Low pressure or suction side typically varies by equipment. Low-pressure refrigerant turns on the carrier HVACR at 50 psi (R22 pressure at 30 degrees) and closes at 100 psi (R22 pressure at 85 degrees).I know I used to have a test where at 90F outside and 75 inside I ran around 270/70. ...
