Ironically in this case doing the job properly reduces costs significantly.
Everything in the chain from the outlets, ductwork, damper, valves, condensers, pipes, tray, fans, component ratings & switchboards can be reduced to a reasonable size.
Which then has peripheral benefits like reduced transport costs, crane lifts, space in service zones between floors/risers, materials & running costs of the completed building

they’re filthy communists i tell ya
