Because replacing your ducts requires opening an enormous percentage of your walls and ceilings.

Instead, the usual practice is to replace your HVAC units with ones that are compatible with your old ducting.

If there is something actually wrong with your ducting, such as poor balance between rooms, then you might want to consider it. But that means you're now replacing your HVAC, your ducts, a significant percentage of your drywall, and repainting the entire interior of your house.
