A home appliance system and an operation method thereof are disclosed. The home appliance outputs product information as a predetermined sound and transmits the sound through a connected communication network, thereby making it easier for a service center at a remote place to check a status of the home appliance. Further, the home appliance system and operation method thereof prevents noise or signal error generated in the procedure of converting product information into a signal of a predetermined frequency band in order to output the product information as a sound, thus enabling stable signal conversion and improving the accuracy of information transmission using the output of sound.
