One of the bigger issues you’re going to face with an old house is having enough power (available room in breaker panel) for multiple units.

You need one power feed for each condenser; the heads get their power from the condenser. A condenser can support multiple indoor heads. In our house, we have 6 heads on 2 condensers, one at each end of the house, using one 240v pairs in the panel for each.

My point exactly. Depending on who built the house it may have 100amp service, unlikely but there is that chance.
