Only a specialist with experience can do this. Use the services of a service center, they will diagnose and find out whether your air conditioner needs to be refueled.

There is also an overabundance of freon. This is the fault of the masters who filled the air conditioner «by eye». An experienced master must correctly determine how much refrigerant is in the pipeline, and add exactly as much as necessary.
