In a vehicular air conditioning apparatus, a connection duct connects a first blower unit having a first blower fan to a side of a casing forming air passages, whereas a second blower unit having a second blower fan, different from the first blower unit, is connected to a lower portion of the casing. By driving the first blower fan and second blower fan simultaneously, air is supplied to a vehicle compartment from the first blower unit and the second blower unit through inside the casing. A controller controls the driving of the first blower fan and the second blower fan.
