Do you add refrigerant to the high or low side?
For systems under a vacuum, once the desired vacuum level has been reached, the vacuum pump has been isolated from the system, and no leaks exist, always charge liquid refrigerant in the high side of the system until high – and low – side pressures equalize and liquid stops flowing.

Can you add refrigerant on the high side?
it is’nt always possible to do, charging into high side is fine, but at a point you will have to switch over to the low side. If you are installing refrigerant into an operational system, charge vapor only through the low pressure port.
What happens if you add Freon to the high side?
The low side is the vacuum side, it will suck the refrigerant out of the can so no “tricks” needed. The high side can put excess pressure into your can – hopefully your can is properly made and will pop out the bottom if overpressurized, but then again your hose or can might burst.
Can I recharge my AC without vacuum?
If you don’t vacuum out an AC system prior to refilling it with refrigerant you will not get maximum performance because there will be minor amounts of air (humidity/moisture) in there. SO by vacuuming an AC system we reduce the pressure so that any water in the system will boil away at ambient temperatures.
Does AutoZone add Freon to cars?
