Hello my name is***** am an ASE Master Technician and I am glad to help you with your question.

Sounds like you have a leak, we use machines to put a vacuum on the system and the machine can sometimes detect a leak. If not you can add a UV dye to the system and recharge it, you will then use a UV light and glasses to search for the leak and you will be able to see it easily. The leak could be coming from the compressor, lines, condenser, or evaporator.
