It is a common misconception that air conditioning means a system which cools the air but that is only partly true. As the name suggests, the system conditions the air which means that it can convert the air into either warm or cold air.

In the heating system, the refrigeration process is reversed i.e. the evaporator coil becomes the condenser and produces heat and the condenser acts as an evaporator coil.
