I would like to know how much money do I need if I want to convert my heat from propane to electric?

You are looking at a completely new furnace so it would run $2k+. How old is your current furnace and what brand and BTUs?

Somewhere between a lot and a bunch :)

Seriously though, we need some more information such as what do you mean by electric: baseboard only, air handler with heat strips only, air handler with heat strips and heat pump, etc? Is your service capable of this? Finally, what do you have now, and what is driving this decision?
