What Affects Split System Installation Cost?
Installation Type
- Back-to-back install (indoor and outdoor units on the same wall) — cheapest option, included in standard pricing
- Short pipe run (up to 3 metres) — typically included in quoted price
- Extended pipe run (3-10+ metres) — adds $50-$80 per metre for additional piping
- Multi-storey installation — adds $200-$500 for working at height and longer pipe runs
Electrical Requirements
- Existing power point nearby — no extra cost for units under 3.5kW
- Dedicated circuit required — adds $200-$400 for units over 3.5kW (mandatory under QLD regulations)
- Switchboard upgrade — adds $300-$800 if your switchboard needs upgrading to support the new circuit
Other Cost Factors
- Roof space access — if piping needs to run through the roof, adds $100-$300
- Bracket mounting — wall or roof brackets for the outdoor unit add $100-$250
- Old unit removal — removing an existing split system adds $150-$300
Running Costs in Brisbane
Split system running costs in Brisbane depend on the unit size and energy rating:
| Unit Size | Cost Per Hour (Cooling) | Daily Cost (8 hrs) | Monthly Estimate |
|---|---|---|---|

Based on average Brisbane electricity rate of $0.30/kWh. Modern inverter systems cost 30-50% less than older non-inverter units.
Multi-Head Split System Costs
If you need to cool multiple rooms, a multi-head split system uses one outdoor unit to power 2-5 indoor units:
- 2-head system — $4,000 – $6,500 installed
- 3-head system — $6,000 – $9,000 installed
- 4-head system — $7,500 – $11,000 installed
- 5-head system — $9,000 – $13,000 installed
Multi-head splits are often more cost-effective than individual units when cooling 3+ rooms, and they only need one outdoor unit — ideal for apartments and townhouses with limited outdoor space.
