The Victorian Government provides the following general guidance based on heating output.
| Room size | Recommended heating output |
|---|---|
| Up to 20m² | 2.5–3kW |
| 21–40m² | 3–5kW |
| 41–60m² | 5–8kW |
| Over 60m² | More than 8kW |
These figures are general guidance, not a substitute for a professional heat-load assessment. Heating capacity may differ from a system’s advertised cooling capacity.
Air Conditioning Installation Melbourne: Selecting the Correct Capacity
Before selecting a unit, consider:
Room dimensions and ceiling height.
Insulation quality and draughts.
Number and size of windows.
Sun exposure and building orientation.
Number of occupants.
Appliances that generate heat.
Whether doors to adjoining rooms remain open.
Melbourne’s seasonal heating and cooling requirements.
For example, a small bedroom with good insulation may need considerably less heating and cooling capacity than a large open-plan living area with extensive glazing.
Air Conditioning Installation Melbourne: Why a Professional Assessment Matters
A professional assessment considers more than the floor area of a room. The installer should evaluate the building’s construction, window orientation, insulation, airflow and expected heating and cooling demand before recommending a suitable system. This helps prevent common sizing mistakes and supports more consistent indoor comfort.
Understanding Victorian Government Air Conditioning Rebates in 2026
