This info can be obtained if the vehicle's now computer monitored pressures can show on a scanner most folks are unlikely to buy …

So when or if a problem comes along you want to know the pressure and without a port can quick use a touchless infrared thermos on lines and know the pressure! This chart shows the relationship between a/c system pressure, and ambient temperature. The low-side is way too low and the high-side too high.

Slowly remove refrigerant. High side <200psi. A clogged orifice tube is a common cause of such problems. The one I installed on my 68 Rogue runs 150 psi on the high side on a hot day, blowing 38 degree air. Refrigerant R134a or HFC-134a is a commercially available hydrofluorocarbon (HFC) refrigerant for use as a long-term replacement for R-12 in new equipment and for retrofitting medium temperature CFC-12 systems. While recharging the system with refrigerant, the 134A manifold gauge pressure should be monitored so the proper amount of refrigerant is used. R-134a Refrigerant Pressure Temperature Chart. A few years back there was immense pressure in the European Union to stop using the HFC R-134a for automotive air conditioning. That being said, there are still millions of cars on the road that […] The high-side pressure may be elevated as the compressor attempts to force the refrigerant past the obstruction. Ass a refrigerant, a liquid capable of vaporizing at low temperature, used in automotive air conditioning, the U.S. Environmental Protection Agency, states that R134A is not flammable at ambient temperatures and not corrosive to metals such as aluminum, … This table represents a pressure temperature chart for R134A. R-134A is a refrigerant frequently used in automobile air conditioning. It has been in use since the early 1990’s and now, in 2019, we are beginning to see it’s popularity wane with the rise of the new HFO refrigerant known as R-1234yf. Pressure: Temperature : Pressure: Temperature : Pressure: Temperature: psig ("Hg) Degrees F : psig: Degrees F : psig: Degrees F (22)-62.38 LOW: HIGH: Need service, possible blockage of the expansion valve or orifice tube. Yf was the first HFO refrigerant to see mainstream attention. The low pressure service port (low-side port) is located in the line that runs from the compressor through the evaporator (firewall) and up to the condensor on the low pressure (suction) side of the system. Helpful when troubleshooting a/c problems. With the A/C turned OFF - On a cold day the pressure will be low, on a hot day the pressure will be high.
