Split System AC Installation
Split System Air Conditioning Installation Adelaide - Properly Wired, Tested and Ready to Run
Most split system units get installed without anyone giving the electrical side a second thought. The unit goes on the wall, the refrigerant gets connected, and the job’s ticked off. What often gets missed is a proper look at the switchboard, the circuit capacity, and whether the wiring can actually handle the load long-term.
In Adelaide’s summers, your air conditioner runs hard for months straight. That’s not the time to find out the installation was underpowered or the circuit wasn’t protected correctly. A faulty setup doesn’t just cause inconvenience — it can become a safety issue.
At Arena Electrical Group, we handle the complete electrical side of split system installations from the dedicated circuit and wiring through to the switchboard connection and final test. Every installation is done to Australian standards and signed off before we leave your property.
What We Handle:
- Dedicated circuit installation for single and multi-head split systems
- Switchboard assessment and upgrades where required
- Wiring from the switchboard to the indoor and outdoor units
- Safety switch and circuit breaker installation
- Installations for new builds, renovations and existing homes
- Multi-split system wiring for multiple rooms or zones
One Installer, No Gaps
Some homeowners end up with two separate trades on the job: one for the unit and one for the electrics, and nobody quite owns the full result. We work alongside your AC supplier or installer and take complete responsibility for the electrical side. If something isn’t right, you’ve got one number to call.
We know how uncomfortable Adelaide summers get, and we know how important it is to get this job done properly the first time. No shortcuts, no loose ends.
We service all Adelaide metro suburbs. Upfront pricing, and available 24×7.

The right split system size depends on the room dimensions, ceiling height, insulation, and sun exposure. As a general guide, a 2.5kW unit suits rooms up to 20m², a 3.5kW unit suits rooms up to 30m², and a 5–6kW unit is recommended for larger open-plan spaces. Arena Electrical Group can assess your Adelaide home and recommend the most suitable and energy-efficient system for each space.
