Modern split-system air conditioner machines work by extracting hot air and humidity from inside a space, pushing it through a compressor and then releasing it outdoors.
The two types of split-system air conditioners are single- and multi-head systems.
Single-head wall-mounted systems work for both small and large rooms. They consist of a single indoor unit and an outdoor condensing unit, providing an efficient and consistent airflow.
Multi-head wall-mounted systems feature multiple indoor units linked to a single outside condensing unit. Compared to the single-head model, a multi-head model is recommended for homeowners who have limited outdoor space or who prefer fewer units installed outside their home.
