Full Answer

In each part of a heat pump, there is a set of coils through which a refrigerant liquid flows. When it passes through one set of coils, it absorbs heat from the ambient air, evaporating into a gas. It is then pressurized and pushed through the other set of coils, where it bleeds off the heat and condenses into a liquid state. In an air conditioner, this cycle only works in one direction, but in a heat pump, the cycle can be reversed. This allows the heat pump to transfer heat out of a home in summer and into a home in winter.

In a traditional heat pump, the indoor coils are situated in a central air handler connected to ducts that run throughout the home. Mini-split heat pumps replace the ducting, where heat can be lost, with wall-mounted blowers in individual rooms. This allows for a greater control of heating and cooling. Multiple indoor units can be connected to the same outdoor compressor.
