I see where you are coming from, because it’s usually the case that centralizing has economies of scale. The surface area of moving cold air and the damage a missed cold spot causes from condensation or a too-cold spot causes an ice jam seems to be a big materials challenge. Cities have centralized steam systems for nearly 100 years, so there are probably different sets of challenges with central AC or folks would have figured it out? It might be something along the lines of the heat exchange system would be ridiculously large?
