Well, I'd argue the method still matters. PTACs heating with a reversed heat pump are going to be energy efficient. When the resistive heater turns on though, not so much.

Depends also on size. Heat transfer efficiency depends on surface area. In theory they can heat to below 0F outside…. If big enough. But many PTAC’s will stop at 40F due to their small size.
