dc inverter air to water heat pump is always efficiency. Once the air in the home reaches the temperature specified on the thermostat, this refrigerant cycle stops completely, restarting only when the home's temperature changes. Each time the cycle restarts, the high efficiency air source heat pump system consumes energy to balance pressure and bring the refrigerant to the correct temperature before the heating or cooling process can begin.
