Heat Pump (reverse cycle air-con) – A heat pump is a HVAC unit that heats or cools by moving heat. During the winter, the indoor coil becomes the condenser and circulates warm air through the conditioned space. In the summer, it reverses the process and the indoor unit is an evaporator that removes heat from your house and releases it outdoors. View the heat pump page.
