Ducted Air Conditioner Sizes
What size ducted air conditioner is best for my home on the Sunshine Coast?
To determine the best size ducted air conditioner for your home on the Sunshine Coast (which has a warm, humid subtropical climate), you’ll need to consider several factors, including the ceiling height, room zone sizes, insulation, exposure to the sun and windows.

- Window size & orientation (especially north/west-facing)
- Number of zones (e.g., bedrooms vs living areas)
- Occupancy & internal heat sources (people, appliances, lighting)
🏡 Example For a typical 4-bedroom single-storey house on the Sunshine Coast:
- Floor area: ~180–220 m²
- Moderate insulation & ceiling height
- Needs a ducted system around 14–16 kW
✅ Recommendations Use zoning: Helps cool only what’s needed, saving power.
- Choose inverter models: More efficient and quieter.
- Install correctly: Poor ducting or oversized units waste energy and reduce comfort.
- Professional heat load assessment: Always best for precision.
