Will I have to replace all my current duct work when I get a heat pump?

No, Mitsubishi ductless heat pumps require no duct work upon installation or operation. The advantages of not using air ducts in a heating and cooling system are:
you will not lose 20-40% of your heat
the air in your home will be cleaner, conditioned air
you will feel even temperatures throughout your home
