We heat our upstairs with a heat pump. We are in the upstate of SC. I don't remember where it is that you live. I would never choose a heat pump if I could help it because although we don't have lots of snow and don't have days and days of below freezing temps, we do get cold and a heat pump has to work really, really hard and unless the emergency heat strip comes on, it does not put out the warm air that an oil or gas furnace would. Ours still works, and we do cool with it effectively in the summer months, but I would choose something else if I had the choice.
