Failure due to air conditioning leakage in a refrigeration device or system is very common. This loss of refrigerant in a refrigeration circuit may be due to a fault in the installation or in the manufacture of the materials used. Likewise, the wear of these or some defect in the outdoor or indoor unit is not ruled out. Therefore, we must proceed to review the symptoms that generate the lack of gases. Once that’s clear, it’s time to locate the leak, thus preventing the engines from being damaged.
