A management apparatus and a management method which can forecast inspection time before the lowering of performance or the occurrence of abnormality in a heat source unit for an air conditioner are provided. The operating condition of the air conditioner heat source unit is monitored by a central monitoring unit of the management apparatus connected to the heat source unit through an information communication network. Operating data of the heat source unit is analyzed so that the lowering of the performance and the advance of the degree of abnormality in the heat source unit are diagnosed. Thus, the loss of a user caused by the failure stop or the performance lowering of the heat source unit is reduced. Further, the load on the heat source unit is grasped by the central monitoring unit so that remote central control is carried out to make the operating cost minimal.
