At Alabama prices a typical heat pump heats a house for about $594 a year, against $576 for a 95% gas furnace; it wins clearly against propane, oil and electric resistance heat, and it also replaces the air conditioner.
Do I need a cold-climate heat pump in Alabama?
Generally not. None of the Alabama cities we track has winters cold enough to require a cold-climate model, although one still helps on the coldest nights.
