Compare every major brand, understand sizing, energy ratings, and running costs — everything you need to make the right choice for your home in 2026.
All prices are supply-only RRP estimates as at mid-2026. Installed prices will be higher. Star ratings reflect overall reliability, efficiency, features, and value for Australian homeowners.
The world's largest AC manufacturer and Australia's best-selling brand for good reason. Daikin's local presence — with Australian-based technical support and one of the widest installer networks in the country — makes warranty claims and service genuinely fast. Consistent build quality across the range, outstanding in extreme Australian heat.
The benchmark for ultra-quiet operation in Australia. Mitsubishi Electric's indoor units consistently achieve the lowest noise levels in the market — ideal for bedrooms and open-plan living. The MSZ-AP and designer EF series are consistently among the highest-rated systems by Australian consumers. Commands a price premium that most buyers feel is justified.
Fujitsu General delivers Japanese reliability at a more competitive price point than Daikin or Mitsubishi Electric. Excellent reputation for long-term durability and strong energy performance. The ASTG range is a consistent favourite among Australian installers for its reliability and straightforward installation. Particularly strong in the mid-to-large capacity bracket.
Panasonic's nanoe-X air purification technology is the most advanced air quality system on the consumer market — it actively inhibits bacteria, viruses, and allergens rather than just filtering them. A genuine differentiator for allergy sufferers or families with young children. Competitive pricing for the feature set. Outdoor units are impressively compact.
Often confused with Mitsubishi Electric — they are entirely separate companies with separate products and warranties. MHI offers solid Japanese engineering at a slightly more competitive price than Mitsubishi Electric. Particularly good in commercial and larger-capacity residential applications. Reliable and robust, if less well-known in the premium residential space.
Samsung's Wind-Free technology — which diffuses airflow through 23,000 micro-holes instead of blasting cold air directly at occupants — is genuinely innovative and highly rated for comfort. Outstanding SmartThings integration for smart home users. Build quality has improved significantly and now competes credibly with Japanese brands. Good choice for tech-forward households.
LG's Dual Inverter compressor technology delivers faster cooling and heating with lower energy consumption. The ARTCOOL range has some of the most attractive indoor unit designs on the market. Strong ThinQ app integration and solid energy efficiency. A credible alternative to Japanese brands at a competitive price point.
Australia's home-grown AC brand, designed and engineered specifically for Australian climate conditions — the extremes of heat and humidity that European and North American systems aren't optimised for. Now backed by Daikin's global manufacturing and supply chain. The go-to choice for many Australian installers when speccing whole-home ducted systems.
Haier has become a credible budget option with improving quality, and now owns the Kelvinator name — a brand once synonymous with Australian refrigeration. Both are fine for rental properties, secondary rooms, or budget-conscious buyers who want basic reverse-cycle functionality without premium features. Build quality and longevity lag behind Japanese brands, but the price difference is significant.
💡 On refrigerants: All new AC systems sold in Australia since 2024 use R32 refrigerant. R32 has a global warming potential (GWP) of 675 — about one-third of the older R410A refrigerant it replaced. If a tradesperson quotes you on an R410A system, it's old stock — ask for R32.
Every system type has a different use case. The right choice depends on your home's size, layout, budget, and how many rooms you need to heat or cool.
A wall-mounted indoor unit paired with an outdoor compressor. Australia's most popular system by far. Handles both heating and cooling from one unit. Modern inverter models are highly efficient and surprisingly quiet.
Two to five indoor units connected to one outdoor compressor. Each room has its own unit that can be controlled independently, but they all share the single outdoor unit. More efficient use of outdoor space and often better value than multiple split systems.
A central outdoor unit connects to ceiling vents throughout the home. All rooms heated and cooled seamlessly with no visible wall units. The premium whole-home solution — quiet, invisible, and can be zoned so you only run the areas you're using.
Ceiling-recessed unit that distributes air in four directions. Common in commercial spaces, but increasingly popular in larger residential open-plan areas. Nearly invisible from below — just a neat grille in the ceiling. Requires ceiling void space for installation.
⚠️ Avoid window/wall box units in 2026. Old-style box units that fit into a window or fixed wall sleeve are inefficient, noisy, and can only cool (not heat). The price difference vs a proper split system has narrowed to the point where a split system is nearly always the better investment — even for a single room.
Undersizing your AC means it runs constantly without reaching target temperature. Oversizing means uncomfortable humidity in cooling mode and short-cycling that wears out the compressor faster. Get the sizing right.
| Room / Area | Approx. Size | Recommended Capacity | Hot / Humid Climate | Cool / Alpine Climate |
|---|---|---|---|---|
| Small bedroom | 10–15 m² | 2.0 – 2.5 kW | 2.5 kW | 2.0 kW |
| Standard bedroom | 15–25 m² | 2.5 – 3.5 kW | 3.5 kW | 2.5 kW |
| Master bedroom | 25–35 m² | 3.5 – 5.0 kW | 5.0 kW | 3.5 kW |
| Living / dining (medium) | 30–45 m² | 5.0 – 6.0 kW | 6.0 – 7.0 kW | 5.0 kW |
| Open-plan living (large) | 45–65 m² | 7.0 – 8.0 kW | 8.0 – 9.0 kW | 7.0 kW |
| Large open-plan / entertainer | 65 m²+ | 9.0 – 12.0 kW | 12.0 kW+ | 9.0 kW |
📐 These figures are a starting guide only. A proper heat load calculation by your installer will also factor in: ceiling height (higher = more volume to heat/cool), insulation quality, number and size of windows, sun exposure and aspect, whether windows are shaded or north-facing, and occupant numbers. Always have your installer do a proper calculation before speccing your system.
Modern AC units are packed with features. Here's what genuinely makes a difference in day-to-day use.
Non-negotiable in 2026. Inverter compressors modulate their speed rather than just switching on/off. 30–50% more efficient, quieter, and longer lifespan. Never buy a fixed-speed unit.
Makes the unit work as a highly efficient heat pump in winter. 3–5 units of heat for every 1 unit of electricity. Never buy cooling-only in an Australian climate.
Allows remote control via smartphone. Genuinely useful for pre-heating or pre-cooling before you arrive home. Standard on most mid-range and above. Check whether a Wi-Fi adaptor is included or sold separately.
All modern units have basic dust filters. Look for antibacterial or nanoe-X filters (Panasonic) if air quality is a priority. Self-cleaning filters save maintenance time.
Reduces fan speed and gently adjusts temperature overnight. Worth having for bedroom installations — look for units with under 19dB indoor noise rating.
Critical in extreme climates. Check the heating operating range — some units stop working at 2°C outdoor temperature; better models (Daikin Alira X, Mitsubishi Electric AP) work down to -15°C.
Samsung SmartThings (Samsung), ThinQ (LG), and Daikin Online Controller all integrate well with Google Home and Amazon Alexa. If you're building a smart home, check compatibility before buying.
After the unit turns off, a drying cycle runs to prevent mould and bacteria growth in the indoor unit. Recommended for humid climates. Adds minor running time but reduces odours and service requirements.
Australia switched to the Zoned Energy Rating Label (ZERL) system in 2024. It's more informative than the old system — here's how to read it.
The ZERL shows separate star ratings for three Australian climate zones: Hot (northern Australia, tropics), Mixed (most capital cities), and Cold (alpine and southern regions). This means a unit that performs well in Darwin's heat might get a different star rating in Melbourne's cold winters — which is exactly what you want to know.
Stars run from 1 to 10. The old maximum of 5 stars has been replaced — a unit that earned 5 stars on the old label now scores around 6 on the new label. Don't be alarmed if a new unit appears to have more stars than an old one.
💰 Every extra star saves approximately $50–$100/year on a standard 6kW split system running in a typical Australian household. For a unit you'll run for 15 years, upgrading from a 5-star to an 8-star system can save $2,000+ over the unit's lifetime — often more than the price difference at purchase.
Based on average Australian electricity rates of approximately 32–38¢/kWh in 2026 and typical usage patterns. Actual costs vary by location, tariff, and usage.
Inverter vs electric heater comparison: A 2.5kW reverse-cycle split system running in heating mode costs around 8–12¢ per hour to produce 2.5kW of heat (due to the efficiency of heat pump technology). A standard 2.4kW electric bar heater costs 77–91¢ per hour for the same output. An inverter reverse-cycle system is 6–8× cheaper to heat with than a bar heater.
Versus gas ducted heating: For most homes in 2026, a modern inverter reverse-cycle system is competitive with or cheaper than gas ducted heating at current gas prices — and has no gas connection costs, no carbon monoxide risk, and no standing supply charges.
