What size split system air conditioner is best for my home in Hervey Bay?
The ideal split system air conditioner size for your Hervey Bay, Queensland, house depends on a number of criteria. Because of the area’s warm, humid subtropical environment, cooling requirements are a top priority. To assist you in selecting the appropriate size, the following general advice and assistance is provided:
| ✅ General Sizing Guide (based on floor area) | |
|---|---|
| Area (m²) | Recommended AC Size |
| 10–20m² – Bedroom | 2.5 kW |
| 20–30m² – Living Room | 3.5 kW |
| 30–45m² – Living Room and Kitchen Combined | 5.0–6.0 kW |
| 45–65m² – Small Apartment | 7.0–8.0 kW |
| 65+m² – Consider Ducted | 8.0–10.0+ kW |
This is for split systems per room or open plan areas. For whole-home cooling, ducted systems ranging from 10–20 kW may be more suitable.
🧮 What Affects the Right Size?
To get a more accurate sizing, consider:
- Room size (length × width × height)
- Insulation quality
- Number and size of windows
- Orientation (north/west-facing rooms get hotter)
- Number of occupants
- Appliances and internal heat sources
- Ceiling height (higher ceilings = more volume to cool)
🌡️ Hervey Bay Climate Notes
- Hot, humid summers with high humidity.
- Moderate winters (heating not a major concern).
- Prioritise dehumidification and energy efficiency.
🔧 Example
If you have:
- A single living area of about 40 m²,
- With average insulation and standard ceiling height,
- You’ll likely need around a 5.0–6.0 kW split system.
If you’re cooling a whole house, say 3–4 bedrooms, two living spaces, and a kitchen, you’re looking at a ducted system sized between 12–18 kW, depending on house design and insulation.
💡 Recommendation
