An inference device obtains an inference value of a time taken to melt frost for defrosting temperature information representing a temperature of an outdoor-side heat exchanger included by an outdoor unit of an air-conditioning apparatus or a state of change in the temperature. In the inference device, the time taken to melt frost is a period during which the temperature of the outdoor-side heat exchanger is stable within a first range. The inference device includes a first data acquisition unit that acquires the defrosting temperature information of the air-conditioning apparatus, and an inference unit that obtains, by using a trained model that infers a time taken to melt frost from the defrosting temperature information and in accordance with the defrosting temperature information acquired by the first data acquisition unit, an inference value of the time taken to melt frost for the defrosting temperature information.
