"Heat Pump vs. Air Conditioner. In many ways, heat pumps are functionally the same as conventional air conditioners. The only real difference is that a heat pump can reverse itself so it can provide heating when needed. ... Air conditioners, heat pumps, and refrigerators all use a similar process to transfer heat energy."
And if it's too cold outside for the heat pump to work it also has a big heating element built in that goes on that is very inefficient.
