We would like to show you a description here but the site won’t allow us.On a 90 degree day, the LOW side reading should be about 70 psi or higher. If the LOW gauge reading is less than this, the A/C system probably needs some additional refrigerant. The actual pressure readings will vary depending on the type of refrigerant (R-134a or R-1234yf) that is in your A/C system.

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.

One of the first refrigerants to go was our friend R-12. At this point in time, in the early 1990’s, R-12 had seen the majority of it’s usage in automobile air conditioning. R-12 was banned in new automobiles and was replaced with by the HFC refrigerant we all know today as R-134a. Now, there are still some R-12 applications out there today.

Step 1. Connect the high-pressure part of your unit’s cooling line with a red port on a gauge. Remember, the red gauge and port are always high-pressure gauges. Attach the red hose (code-approved) to the high-pressure port using flare-fittings on your cooling unit. Make sure the red hose can handle high pressure.Marketing Brochures. GENERAL.
