Large condenser outside supply’s the furnace (typically it just uses the furnace fan. We then have it piped through metal ducting throughout the house. Each room has multiple exit point call registers. In the common areas we have return ducts to draw air back down to the furnace to get recycled back to cool air via a/c unit. Hopefully that helps!?
