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.
