A visual inspection will have to be performed to check for dye and/or oil (some manufacturers put UV dye in A/C schemes from the factory).

Check all AC parts including the AC compressor front seal & evaporator drain tube. If the refrigerant leak is not evident, verify that dye is in the system or add dye (one method is with a dye injector).

You may then use an ultraviolet light (UV Light) also called a black light, to inspect all AC components.

Check the entire system with an electronic leak detector, the evaporator may be checked at the evaporator drain tube.

After the fix has been made, hook up an AC vacuum pump, and let the system stay in a vacuum

for at least fifteen minutes. Turn the vacuum pump off and watch the AC gauge to see if the vacuum holds. If a loss of vacuum is noted, this could indicate a big leak, perhaps from an o-ring on a element that was just worked on. Tip when adding refrigerant oil; After adding oil to the scheme near or in the compressor, turn the compressor by hand ten revolutions to prevent harm to the compressor (oil can not be compressed). Warnings; 1. Do not charge refrigerant into the high side 2. Do not over-charge the system, harm to the compressor may occur. 3. Always wear safety glasses when working on air conditioning systems, even with the freon got rid of oil may spray from an open AC line caused by trapped freon all of a sudden passing through a restriction.

You will need an AC Gauge Set, an Electronic Refrigerant Leak Detector, an AC vacuum pump, a UV Light and a thermometer.
