What is the difference between
DUCTED, SPLIT or EVAPORATIVE AIR CONDITIONING
Ducted reverse cycle air conditioning is a closed system where the air is recirculated through an indoor unit mounted in the ceiling space. It can be ducted to the whole home with zones to close off rooms when not required, which maximises the efficiency of the system.
A wall-split is designed to air condition only one room. Some systems have many heads with one outside unit (multi head splits).
An Evaporative cooler is mounted on the roof and delivers fresh air to the whole of the home via a ducted system. It is important to remember that cooled air inside the building is not recirculated, so some doors or windows must be left open for this air to escape, providing the whole building with a complete change in air at least every two minutes.
