What is a Ducted Reverse Cycle Air Conditioning System?
A ducted air conditioning system consists of a single outdoor condenser connected to an indoor fan coil unit, typically located in the ceiling or under the floor. Conditioned air is distributed through a network of insulated ducts to multiple rooms via air diffusers, ensuring a consistent temperature throughout the home or office. A central return air grille filters and circulates air back into the system for heating or cooling.
All modern ducted systems installed by AA Plus Energy are reverse cycle, providing efficient heating and cooling with inverter-driven compressors for precise temperature control and quiet operation.
Ducted Airconditioning
How do Ducted Air Conditioning Systems work?
Ducted systems use the vapour compression refrigeration cycle, where refrigerants absorb and release heat by changing states between liquid and gas. This process makes them highly efficient compared to traditional gas heaters or electric systems, using electricity mainly to power the compressor, fans, and sensors.

Benefits
Factors That Affect Ducted Air Conditioning Installation Costs
Installing a ducted system typically ranges from $6500 to $20000 (including GST), influenced by the following variables:
System Capacity
Each additional unit increases both equipment and labor costs.
Indoor Unit Location
Installing units on external walls simplifies installation. Internal wall setups may require extra piping, drainage pumps, and structural modifications.
Distance Between Indoor and Outdoor Units
Longer refrigerant lines, cables, and more refrigerant increase material and labor expenses.
Condenser Placement
Ground-level installations are straightforward. Rooftop or elevated placements involve additional brackets or platforms, impacting cost.
Electrical Supply and Switchboard Location
The complexity of running a dedicated power circuit depends on the proximity of your switchboard to the outdoor unit.
System Brand and Features
Advanced models with smart technology or premium features influence the final price.
