Why Choose a Split System Air Conditioner?
Split system air conditioners are one of the most popular and efficient cooling and heating options for Australian homes and businesses.
- Energy-efficient – cool or heat just the room you need.
- Fast comfort – reverse cycle models provide instant heating and cooling.
- Quiet operation – whisper-quiet indoor units, perfect for bedrooms.
- Better air quality – built-in filters reduce dust, allergens, and pollutants.
- Flexible design – install in single rooms or multiple areas with multi-head systems.
Step by Step How To Size Your Split System Airconditioner.
Step 1: Measure the Room Size
Start by measuring the length and width of the room in metres.
Formula
Room Area = Length × Width
Example:
- Room length: 5m
- Room width: 4m
Room area = 20m²
This number is the starting point for determining the required cooling capacity.
Step 2: Match the Room Size to the Air Conditioner Capacity
Split system air conditioners are rated in kilowatts (kW), which indicates how much cooling capacity the system can produce.
As a general guide:
| Room Size | Recommended Aircon Size |
| Up to 10m² | 2.0 – 2.5 kW |
| 10 – 20m² | 2.5 – 3.5 kW |
| 20 – 30m² | 3.5 – 5.0 kW |
| 30 – 40m² | 5.0 – 6.0 kW |
| 40 – 60m² | 6.0 – 7.5 kW |
| 60m²+ | 7.5 – 9.5 kW |
Example:
A 20m² bedroom will typically require a 2.5kW to 3.5kW split system.
Step 3: Consider Ceiling Height
Higher ceilings mean more air volume to cool.
Standard ceilings (2.4m) are used in most calculations. If your ceilings are higher than this, you may need to increase the system size.
Examples:
- Standard ceilings: Use the normal sizing guide
High ceilings (2.7m+): Increase capacity by ~10–20%
Step 4: Factor in Sunlight and Insulation
Rooms exposed to direct sunlight require more cooling power.
Factors that increase cooling requirements include:
- Large north or west facing windows
- Poor insulation
- Glass sliding doors
- Dark roof spaces above the room
If your room receives strong afternoon sun, it may require a larger air conditioner capacity.
Step 5: Consider the Number of People in the Room
More people = more heat.
As a general rule:
- Add around 0.15kW of cooling for each additional person regularly in the room.
Example:
A living room used by 4–5 people may need a larger system than the same sized bedroom.
Step 6: Heat Generating Appliances
Electronics and appliances produce heat which increases cooling demand.
Common heat sources include:
- Televisions
- Computers
- Gaming systems
- Kitchen appliances
Rooms like media rooms or home offices may need slightly larger systems.
Step 7: Open Plan vs Closed Rooms
Open plan areas often require larger air conditioners.
If your split system is cooling:
- A kitchen + living room
- A dining area + lounge
The system may need to be sized for the entire open space, not just one section.
Example Split System Sizing Calculation
Room details:
- Size: 5m × 4m (20m²)
- Ceiling height: 2.4m
- Moderate sunlight
- Two occupants
Recommended system size:
2.5kW – 3.5kW split system air conditioner
A 3.5kW system would typically provide comfortable cooling for this room.
