An apparatus for managing at least one heat source unit for an air conditioner, comprising: a central monitoring unit connected to said heat source unit for said air conditioner through an information communication network and for carrying out remote central control upon said heat source unit for said air conditioner; wherein: said central monitoring unit includes a control unit for managing said heat source unit for said air conditioner; and said control unit includes: means for estimating temperatures of respective portions of said heat source unit in operation based on one of a temperature history during start-up of said heat source unit and a temperature history during stop of said heat source unit, said temperature histories being transmitted through said information communication network; means for averaging temperature in cyclic operation condition of said heat source unit for a predetermined period, said cyclic operation condition having an operating cycle of operation, dilution and stop; means for storing said averaged temperature data into a storage unit in time series; means for comparing said temperature data stored in time series with said temperature data of said respective portions estimated by said estimating means; means for detecting a variation, with time, in lowering of performance and/or degree of advance of abnormality in said heat source unit on and after start of use of said heat source unit, based on a comparison result between said stored temperature data and said estimated temperature data; means for estimating degree of deterioration of said heat source unit on and after said start of use based on said variation with time; and means for determining maintenance time from a predetermined deterioration threshold value and said estimated degree of deterioration. 5. An apparatus for managing at least one heat source unit for an air conditioner according to any one of claims 1 to 4, further comprising: means for comparing a temperature history during operation of said heat source unit with a pattern of a temperature history during occurrence of abnormality stored in said storage unit in advance, so as to conduct diagnosis on abnormal condition of said heat source unit. 6. An apparatus for managing at least one heat source unit for an air conditioner according to any one of claims 1 to 4, further comprising: means for changing control logic concerning start and stop of said heat source unit in accordance with said degree of deterioration estimated by said means for estimating said degree of deterioration on and after said start of use based on said variation with time. 7. An apparatus for managing at least one heat source unit for an air conditioner according to any one of claims 1 to 4, further comprising: m
