Any AC system consists mainly of four major components: Compressor, Condenser, Expansion Valve and Evaporator.

A split system air conditioner consists of indoor and outdoor units that work together (split apart).

The parts of a split system air conditioner include a compressor, fan, condenser coil, evaporator coil and refrigerant.

The condenser coil (with fan) is installed outside and connects to the evaporator coil (with expansion valve) which is inside the AC space.
