The details

Unlike conventional split air conditioners that require a separate outdoor compressor unit for every room, this advanced multi-split air conditioner system is designed to power three rooms from a single compressor. This not only improves both outdoor space and external aesthetics, it also saves on expensive installation and running costs too. Plus, each indoor unit has its own remote control, allowing for individual control of all air conditioning units.

The stylish unit is an air conditioner for all seasons. It features both a heating and cooling mode to help you remain toasty in the winter, and cool in the summer. Plus, there's even a built-in dehumidifier which helps remove excess moisture from the air. The multi split Air Conditioning System comes with an impressive 5 year warranty..
