Acceptable operating pressure ranges for Vintage Air systems (R134a): High-side pressure: 160 to 250 PSI. NOTE: A general rule of thumb is two times the ambient (daytime) temperature, plus 15 to 20%. Low-side pressure: 6 to 18 PSI in a steady state. Center duct temperature: 36 to 46° F. Charge as follows: R134a = 1.8 lb.For the normal running pressure in an R134A system, the coil should run at 22 pounds per square inch at the lowest temperature, 45−20 = 25 degrees Fahrenheit. Similarly, at the highest temperature, 60−20 = 40 degrees Fahrenheit, the coil should run at 57 psi. In other words, the normal running pressure of R134A is between 22 and 57 psi …Most automotive refrigerant is today is R134A.
