It may be worth doing IF the house is properly insulated and sealed. Installing any high performance heating and cooling system in a bad building will not reduce your energy bills. Ensure the house is properly insulated, air sealed, and has insulated windows. Then, size the heating and cooling system appropriately and you will find you need a much smaller system because of the reduced loads...or your existing system might not cost that much to operate anymore.
