Checking Gas on Air conditioning Systems
Refrigerant pressure can only be accurately checked whilst the Air conditioning unit is running. Either you can distinguish with a amp meter or by the use of refrigerant gauges, this type of act can or must be performed only by an authorized personnel.

If there is a lack of refrigerant in any system it means that there is a leak somewhere!...
Ensure that the correct gauges are used on a particular system be it R22 or R410a.

A technician's safety comes first! Checking the pressure on a R22 unit is straight forward and easier to get an accurate reading. On an inverter unit, it is more difficult, but possible to get a good idea of the pressure in the system. Remember that the pressure in the system is affected by the ambient temperature. On a cold day a unit's pressure will look lower than if you checked on a hot day.
