Heat Pump vs. AC: Which Is Right for Me?
Air conditioners tend to use a good amount of electricity, and you should remember to include the cost of running your furnace in the overall cost. So a heat pump can be more cost-effective to install, but an AC might be less costly to run in certain climates. Most cost-effective: Heat pumps.
Coefficient of performance
Coefficient of performance. The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [1] [2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.

Heat Pump, Renewable Energy | Benefits of Daikin Technology
A heat pump is energy saving technology that conveys heat without the need to generate heat. There is heat in the air even in places that are generally considered cold: for example, the North and South poles. However, because the amount of heat is small, these places feel cold. When the amount of heat is large, the temperature is high.
