Ducted air conditioners are popularly known as Central cooling AC systems and they can be found in many shopping malls, public, and commercial buildings. It comes with a central chamber with ducts that lead to several vents. The air is treated in this chamber. The treated air is then sent through a connection of ducts to all rooms with the use of fans. Ducted air conditioners can be used for keeping big rooms/areas cool and helps maintain the same level of cooling throughout the room/area. On the other hand, the split air conditioners have separate cooling units and compressors for each room. This is a common feature for many standard rooms and offices. The split air cooling systems deliver a colling temperature that can be controlled separately.
