Bedroom Air Conditioner Guide
Choosing the right air conditioner for your bedroom can make a huge difference to your sleep, comfort and running costs. This guide explains what size system you may need, which features matter most, and which brands are best suited to bedrooms.
What Size Air Conditioner Do I Need For My Bedroom?
The size of your bedroom is the biggest factor when selecting an air conditioner, but ceiling height, windows, insulation and sun exposure also matter.
| Bedroom Size | Recommended Capacity | Best For |
|---|---|---|
| Small Bedroom Up to 12m² |
1.5kW - 2.0kW | Guest rooms, kids rooms and smaller bedrooms |
| Standard Bedroom 12m² - 18m² |
2.0kW - 2.5kW | Most standard Perth bedrooms |
| Large Bedroom 18m² - 25m² |
2.5kW - 3.5kW | Larger bedrooms or rooms with more sun exposure |
| Master Bedroom 25m²+ |
3.5kW - 5.0kW | Master suites and larger rooms |
Other Factors That Affect Sizing
Sun Exposure
Bedrooms with large west-facing windows or strong afternoon sun may need a larger system.
Insulation
Poor insulation can make a room harder to cool and heat efficiently.
Ceiling Height
Higher ceilings increase the total air volume, which can affect system sizing.
