Computing device 110 can then determine whether the event associated with the HVAC equipment of the additional facility corresponds to a fault occurring in the equipment based, at least in part, on the input previously received from the user (e.g., the input indicating the audio sensed during the event(s) associated with the operation of HVAC equipment 102-1, 102-2, . . . , 102-N corresponded to a fault(s)). For example, computing device 110 can compare the audio (e.g., the profile of the audio) sensed during the event associated with the HVAC equipment of the additional facility to the audio (e.g., to the profile of the audio, stored by computing device 110) sensed during the event(s) associated with the operation of HVAC equipment 102-1, 102-2, . . . , 102-N previously indicated by the user as corresponding to a fault(s) to determine whether the audio sensed during the event associated with the HVAC equipment of the additional facility matches the audio sensed during the event(s) associated with the operation of HVAC equipment 102-1, 102-2, . . . , 102-N previously indicated as corresponding to the fault(s). If the comparison indicates a match, computing device 110 can determine that that the event associated with the HVAC equipment of the additional facility corresponds to the matching fault.
