I plan to buy a house in the next 12 months. I'm looking for a modest
three bedroom brick ranch.

Most of the homes around here (Louisville KY) have natural gas heat. In
recent years, at least locally, natural gas has become much more expensive
than electric heat. So given a typical ranch with central heat and air
(and shared ductwork) I'm wondering about how much might it cost to either
get an electric furnace or perhaps a heat pump?
