Split air conditioning systems consist of an indoor unit, responsible for circulating cool air, and an outdoor unit, which extracts heat from the indoor space. The distinction between single split and multi-split systems lies in their ability to cool multiple rooms simultaneously. While single split systems cater to a single room, multi-split systems can handle up to five rooms with a single outdoor unit.

Single split air conditioners consist of a single indoor unit and a corresponding outdoor unit.

The indoor unit can be installed on a wall, ceiling, or floor, depending on the model and your preferences.
