Depending on the fault reported by the customer, refrigeration units are tested to replicate the fault reported by the customer. Once the technician encounters the fault a diagnosis is made and the customer is the contacted with a quotation. Upon completion of the repair the unit is tested again to ensure that the diagnosis made was correct and that the unit is functioning correctly. Pressure tests are done on all fridges / freezers prior to re-gassing to ensure that all brazing joints are sealed and to confirm that there is no leakage internally.
