A split system is a type of central air conditioning, where the compressor and the condenser are in two separate units. The air conditioner is split into two sections and each section contains its own fan, coil, and refrigerant.
The split system is also called a "compressor-condenser" system. Split systems are typically used in smaller homes or as an alternative to central air conditioning for larger homes.
The main advantage of this system is that it provides more flexibility than a standard central HVAC installation. For example, if one unit breaks down there will still be cooling available from the other unit.
Split systems are also easy to install because they do not require as much space as a single large unit would need; they can be installed in small spaces such as hallways, closets or attics.
