Split-system air conditioning installation cost in Brisbane
For one frequently used room, start with a capacity assessment based on climate, orientation, insulation, ceiling height and glazing. If several rooms need conditioning, ask how the proposed layout works with doors closed.
Worked budget
A Brisbane supplier lists starting prices of $2,139–$2,569 including GST for a 2.5 kW split system, supplied and installed, depending on the brand.
| Scenario | Rate per system | Base total |
|---|---|---|
| Low | $2,139 | $2,139 |
| Medium | $2,249 | $2,249 |
| High | $2,569 | $2,569 |
The medium rate uses the supplier’s published middle option. Totals exclude contingency and any separately priced work.
The three prices are for published Fujitsu, Mitsubishi Electric and Daikin options respectively. They assume a single-storey installation on a slab, up to 4 m of pipe and a new dedicated circuit.
Ask the installer to confirm capacity and price extra pipe, a switchboard upgrade, wall mounting or old-unit removal separately.

What to include in the scope
Compare the same model and capacity before comparing labour. Longer pipe runs, switchboard work, condensate drainage and wall brackets can sit outside a standard back-to-back installation. Confirm refrigerant handling and electrical licensing with the installer.
Refrigerant and associated electrical work must be done by appropriately licensed professionals.
