There are 3 ways to detect AC system leaks as we use in a AC repair shop the most common is to add freone gas with a UV dye to the AC system then using a UV torch you look over the AC system components and pipes with the AC system on as it circulates the UV dye will appear and you can detect it with the torch.

Second is to pressure test the system with nitrogen using a pressure gauge you fill the system with nitrogen then whilst under pressure you watch the gauge for any pressure drop but this can take time to detect if it is a minor leak.

Lastly you can buy a special AC freone gas which has a chemical in it which you put into the system and then you would check around the system with a special sniffer device that detects the chemical when it leaks out of the system.
