The article doesn’t go into it, but a key advantage they have is that heat pumps move heat, rather then trying to generate it. So they can move a lot more heat into your house than would be generated by running the electricity they use through a resistor. This makes them effectively more than 100% efficient (the exact amount depends on temperature) as compared with burning a fuel or resistive heat.

    You don’t need additional AC, a heat pump is an AC. For very cold, you’re right, but it has to be VERY cold, like 0F or lower. My last heat pump system had fall back heating coils which are only 100% efficient opposed to a heat pump’s >100.
