At North Carolina prices a typical heat pump heats a house for about $744 a year, against $748 for a 95% gas furnace, so it is cheaper to run even before counting that it replaces the air conditioner.
Do I need a cold-climate heat pump in North Carolina?
Generally not. None of the North Carolina cities we track has winters cold enough to require a cold-climate model, although one still helps on the coldest nights.
