Yes, but the comparison is not between the AC and a heat pump, but between an electric resistance heater and a heat pump. Heat pump's COP is greater than 100% as it takes less energy to heat the air inside than the energy of the heated air while a resistance heater is 100% so is less efficient. In other words: a 10K Watt resistance heater will consume 10 KWh in an hour, a 10K Watt heat pump will consume 2-5 KWh over the same time depending on the temperatures and construction.
