You may also want to look into geothermal, but it might not make as much sense in NC as it would in Michigan.
The question becomes, which will be cheaper during the life of the furnace.
Which furnaces last longer? What would be the increased cost of running both gas lines and electric to your furnace so if natural gas goes up by 500% you could switch easily.
I had an electric water heater at my old apartment, and now have natural gas heat, water heater and stove. So this summer when I'm not using the heat, I will see how much it really costs to run a water heater and if electric was cheaper or not.
My heating bills would be about $140-$150 using natural gas furnace & water heater for 1 month in a 1600 sq. foot house with average insulation in Ohio. Is there anybody using electric that could give a comparison on how much it is per month?
(It is better than my co-worker that goes through 150 gallons of heating oil @ ~$3 gallon each month)
