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.

You need at least a 50 degree IWB and 55 degree ODB at minimum to measure superheat accurately. You can block the coil to simulate your ODB target if it's too low, but be careful how much you raise the head pressure or your SH will drop to 0 degrees. Use a superheat charging chart to determine whether or not you can check the charge.

A liquid restriction would result high superheat (warm suction line). The high head probably due to the other guys overcharging, trying to get the suction pressure up. But the low air problem would result in high head pressure in the heat cycle.The low-pressure side, when connected to the gauge, should read less than 100 psi. PSI is the common measurement for pressure used in terms of pounds per square inch. By the time the refrigerant reaches these lines it has lost most of its heat and has collapsed into a liquid state, taking up less volume. This leads to a low-pressure environment ...It's hot here in AZ - 110 degrees f , i heard teh outside temp affects pressure. Q on my 12 yr old r22 tempstar is 340 psi on high side too much pressure?
