The truth is, ducted air systems are an investment — they add comfort, value, and efficiency to your home. But costs can vary depending on your home’s size, layout, and the features you choose. In this guide, we’ll break down the average prices, key cost factors, and real examples from Brisbane, Sunshine Coast, Moreton Bay and Hervey Bay so you can budget with confidence.

What Affects the Cost of Ducted Air Conditioning?
Not every home is the same — here are the main factors that impact price:
Home Size & Layout
Larger homes require higher-capacity units (kW rating) and more ducting.
Two-storey homes often need extra zoning and outlets.
Zones & Outlets
The more rooms you want to cool/heat, the more ducting and outlets are needed.
Typical homes have 4–7 zones.
Roof Space & Access
Easy roof access keeps costs lower.
Steeper roof pitches or tight spaces can add labour time.
System Efficiency & Brand
LG ducted systems are designed for reliability and energy savings.
High-efficiency units can cost more upfront but reduce long-term running costs.
Smart Controls
Adding AirTouch 5 or LG ThinQ Wi-Fi control increases upfront cost but delivers big convenience and efficiency gains.
