You are right. Most do heat pumps with mini splits for each zone. However, ducted houses can certainly use heat pumps with an air handler. Typically this translates to heat pump replaced outdoor condenser (ac unit)and the air handler replaces the indoor furnace.

If the furnace is a serviceable natural gas unit, keep it. It makes a better backup than strip heat.
