Best Split System Air Conditioners in Australia 2025
A split system reverse cycle air conditioner is the most popular home cooling and heating solution in Australia. With dozens of models from Daikin, Mitsubishi Electric, Samsung, LG and others, choosing the right one for your home can be daunting. This guide covers the best split system air conditioners available in Australia in 2025 across all budgets and room sizes.
How to Choose the Right Size Split System
Choosing the right kW capacity is the most important decision. A unit that's too small won't cool or heat effectively; one that's too large will cycle on and off too often and waste energy.
| Room Size | Recommended Capacity |
|---|---|
| Small bedroom (up to 20m²) | 2.0–2.5kW |
| Standard bedroom (20–30m²) | 2.5–3.5kW |
| Large bedroom / small living (30–45m²) | 3.5–5.0kW |
| Standard living area (45–60m²) | 5.0–7.0kW |
| Large open-plan area (60–80m²) | 7.0–9.0kW |
Best Budget Split System: Hisense Energy Pro (2.5–6.0kW)
RRP: ~$799–$1,299
Hisense's Energy Pro range has become one of Australia's best-selling split systems on price. The inverter compressor, 5-star energy efficiency and sleek design deliver excellent value. Wi-Fi control via the HiSmart app comes standard on most models. The 5-year compressor warranty provides peace of mind. If you're fitting out a bedroom or home office on a budget, the Hisense Energy Pro is hard to beat.
Best Mid-Range Split System: Samsung WindFree Elite (2.5–6.3kW)
RRP: ~$1,199–$2,199
Samsung's WindFree technology disperses cool air through 23,000 micro air holes rather than a direct stream, eliminating the uncomfortable cold draft of conventional air conditioning. This is a genuinely innovative feature that makes the Samsung WindFree noticeably more comfortable than conventional units. SmartThings app integration is excellent. Very quiet indoor unit (19 dB on the smallest model). An outstanding choice for bedrooms and living areas.
Best Premium Split System: Daikin Ururu Sarara (2.5–6.0kW)
RRP: ~$2,499–$3,799
Daikin's Ururu Sarara is widely considered the best split system available in Australia. It's the only residential air conditioner that can both humidify and dehumidify, extract fresh air from outside, and purify indoor air — all while running at an extraordinary 7.5 star energy efficiency rating. The operating noise is barely perceptible at 19 dB. For anyone who wants the absolute best and is willing to pay for it, the Ururu Sarara is unmatched.
Best Value for Money: LG Artcool (2.5–9.0kW)
RRP: ~$1,099–$2,999
LG's Artcool split system combines an attractive panel design with solid performance and LG's ThinQ smart home integration. The dual inverter compressor is very energy efficient and operates reliably across a wide temperature range. Available in a full range of capacities from bedroom to large open-plan living. Excellent 10-year compressor warranty provides outstanding peace of mind.
Best Quiet Split System: Mitsubishi Electric MSZ-EF (2.5–6.1kW)
RRP: ~$1,699–$3,199
Mitsubishi Electric's MSZ-EF series (also called the Design Series) is renowned for its exceptional quietness — operating as low as 19 dB on heating mode. The slim, premium design is a popular choice for living areas where aesthetics matter. 3D airflow distribution ensures the room is evenly conditioned. Mitsubishi Electric's reputation for reliability in Australia is excellent.
Key Features to Compare When Buying

- Noise level (dB): Under 20 dB indoor unit is excellent; under 25 dB is good

- Warranty: 5–10 years on the compressor is best
