1. An air conditioner comprising:
a display;
a compressor;
a heat exchanger connected to the compressor;
a pressure sensor provided along a first flow path of refrigerant, the first flow path including an outlet of the compressor and an inlet of the heat exchanger;
a temperature sensor provided along a second flow path of the refrigerant, the second flow path including an outlet of the heat exchanger; and
a processor operatively connected to the compressor, the pressure sensor, and the temperature sensor, the processor configured to:
acquire a reference index value, during an operation, based on a first reference pressure measured by the pressure sensor and a first reference temperature measured by the temperature sensor,
acquire a measurement index value, during a preset cycle after the operation, based on a first measurement pressure measured by the pressure sensor and a first measurement temperature measured by the temperature sensor,
control displaying of, on the display, a status indicating a shortage of the refrigerant based on a comparison of the reference index value and the measurement index value, and
stop the compressor, based on the reference index value and the measurement index value.
