try mo pa check yung high pressure and low pressure hoses kasama na yung couplings nung 2. you should have brought it to a reliable ac shop kasi kung reliable yung napuntahan mo, baba lahat ng major parts ng a/c system mo, like condenser, evaporator and compressor pati yung low and high pressure hoses and they'll be checking it by submerging sa water to see if bubles are formed.

Paano ba na-check yung condenser mo binababa ba at kinapakapa lang for wet areas.
Yung iba kasi tamad na ac technician kakapain lang kung may basa sa condenser, e malapit yon sa radiator kaya if tuyo agad yung pinagsingawan.
