A method of controlling a hot water supply air-conditioning system including an outdoor unit that includes a compressor configured to compress a first heat medium, and is configured to supply the first heat medium, a hot water supply unit configured to generate hot water using the first heat medium supplied from the outdoor unit, an indoor unit configured to perform air conditioning using the first heat medium supplied from the outdoor unit, and a shutoff unit configured to shut off the first heat medium flowing into the indoor unit, the method comprising:

• in a case in which the first heat medium leaks in the indoor unit, shutting off the first heat medium flowing into the indoor unit using the shutoff unit, and continuing operation of the compressor to continue supply of the first heat medium from the outdoor unit to the hot water supply unit.

A control apparatus for use in a hot water supply air-conditioning system including an outdoor unit that includes a compressor configured to compress a first heat medium, and is configured to supply the first heat medium, a hot water supply unit configured to generate hot water using the first heat medium supplied from the outdoor unit, an indoor unit configured to perform air conditioning using the first heat medium supplied from the outdoor unit, and a shutoff unit configured to shut off the first heat medium flowing into the indoor unit, wherein

• the control apparatus is configured to, in a case in which the first heat medium leaks in the indoor unit, perform control to shut off the first heat medium flowing into the indoor unit using the shutoff unit, and continue operation of the compressor to continue supply of the first heat medium from the outdoor unit to the hot water supply unit.
