Hey Jerri, the price difference between the two Advent Air part numbers you mentioned is the part # ADV86SR only comes with the upper unit whereas the part # ADV92SR also comes with the lower vent assembly and start capacitor. It's basically a complete kit for a new install whereas the part # ADV86SR would be if you already had those parts and just needed the top replacement part.
I know you have an Advent unit currently but if it was bought before January of 2025 it uses a different refrigerant and the lower air box would not work so you'd have to get the complete kit.
