A method of operating an aircraft air conditioning system is includes delivering cabin air to a lower recirculation heat exchanger included in a lower cooling zone to generate lower cooled recirculated cabin air and delivering the cabin air to an upper recirculation heat exchanger included in an upper cooling zone to generate upper cooled recirculation air. The method further comprising generating power via a power system, and invoking, via the controller, a recirculation ground maintenance mode to command the power system to deliver power to one or both of the lower cooling zone and the upper cooling zone so as to output one or both of the lower cooled recirculated cabin air and the upper cooled recirculated cabin to an aircraft cabin.
