Hello friend, if it is punctured and the pipe is embedded (inside the cabinet), you can adapt an external grill, you do not need to buy another refrigerator, you put a grill that will work as a condenser, the size will depend on the capacity of the compressor, depending on whether it is a unit of 1/3, 1/4, 1/5 or 1/6 hp, the technician who does the job should recommend the size of the grill for you to buy, anyway, it is good Verify that it is indeed leakage, because the systomas that you indicate also apply when the motocompressor decompresses and loses performance, the technician you hire must verify that it has indeed leaked by pressurizing the system with nitrogen.
