Split ducted Air Conditioning consists of an indoor and outdoor unit, the indoor section is concealed in the roof of the property. The air is transported throughout the home via ductwork in the ceiling. Typically one duct goes to each room and the air is directed into the room via an outlet or vent. 

Split ducted systems are controlled via a control panel whereby temperatures can be set and different parts of the house can be zoned so you can cool/heat as many or as few rooms as you like. 

Pros: 

• Cools and heats the entire home. 

• Quiet operation. 

• Return air filters help optimise air quality. 

• The control panel and zoning gives the homeowner better control over the 

system. 

• Zoning allows for greater energy efficiency. 

Cons: 

• Higher initial investment cost. 

• Modifications to an established home may be required.

These systems consist of an indoor and outdoor unit with interconnecting pipework, The  installation is very similar to that of a Hi wall split system with the exception of the indoor section  being mounted flush to your ceiling. These systems are typically found in commercial premises,  However they are versatile, The indoor section is square with one louver located on each side and the  return air and filter in the center of the unit allows the air to evenly distribute throughout the  room. 

Pros: 

• An effective way to air condition a single space. 

• Effective way to air condition a room with no external walls. 

• Slim-line look indoor section - Flush mounted to the ceiling. 

• Typically quick installation. 

• Cost effective operation. 

Cons: 

• Large penetration required for indoor section. 

• Some modifications may be needed to support indoor section weight. 

A packaged air conditioning unit is not considered a split system, This is due to the fact that the outdoor and indoor sections are both within one unit. These systems complete the entire heating or cooling effect outside the property and supply the air into the space via metal ductwork. 

These styles of systems are typically seen in commercial and industrial applications, This is mostly due to the size and weight of the systems, along with the penetrations needed to allow for the ductwork in and out of the package unit. 

Pros: 

• All mechanical components are easily accessible in one location. 

• Designed to air condition large open spaces. 

Cons: 

• Higher initial investment cost. 

• Rooftop may require reinforcement to support the weight of the system.
