Choosing the Right System
- 1 Split system: single room or open plan
- 2 Multi-split: one outdoor unit serving multiple indoor heads
- 3 Ducted: whole-home solution via ceiling ducts
- 4 Evaporative: only effective in hot dry climates
ARCTick Licence is Mandatory
Any work involving refrigerant must be done by a technician holding an ARCTick licence.
⚠️ Watch out: Never hire someone without an ARCTick licence to install a split system.
Running Costs and Star Ratings
A 5-star system uses roughly half the energy of a 2-star system. Running a 7kW split system costs approximately $0.30–$0.60 per hour.
Maintenance
- 1 Clean filters every 3 months
- 2 Annual service by a qualified technician
- 3 Keep outdoor unit free of debris
- 4 In coastal areas, hose down outdoor unit regularly
