For most Australian homes in 2026: a Daikin, Mitsubishi Electric or Mitsubishi Heavy Industries premium split for rooms that run daily, 2.5kW bedroom units from $1,900 installed and 7kW living areas from $3,000. A Fujitsu or Rinnai covers most other rooms for $300–$500 less, and budget brands only belong where the aircon rarely runs. The brand matters less than the size being right and the installer being good.
How we rank
Three factors, weighted in this order: seasonal efficiency (the AEER/ACOP numbers on the Zoned Energy Rating Label, not the headline star count), serviceability (parts availability and technician familiarity in Australia, the thing that determines whether a ten-year-old unit gets fixed or replaced), and installed price from our quote database. We don't take placement fees and installers can't pay to move up the list.
The rankings
| Tier | Brands | 2.5kW installed | 7kW installed | Buy it when |
|---|---|---|---|---|
| 1. Premium | Daikin, Mitsubishi Electric, Mitsubishi Heavy Industries | $1,850–$2,300 | $2,950–$3,500 | The room runs daily, efficiency and quiet operation pay for themselves |
| 2. Strong mid | Fujitsu, Rinnai, Panasonic, LG | $1,500–$2,100 | $2,400–$3,200 | Most rooms, most budgets, the value sweet spot in 2026 |
| 3. Solid budget | Haier, Midea, Gree, TCL | $1,200–$1,800 | $1,900–$2,700 | Rentals, spare rooms, occasional use, insist on the 5-year warranty |

Why the premium tier leads
Daikin, Mitsubishi Electric and Mitsubishi Heavy Industries earn the top spot on the unglamorous stuff: wide service networks, parts still available a decade in, quiet outdoor units (which matters on small blocks and for strata approvals), and consistently strong performance at temperature extremes, the 43°C afternoons where budget units visibly fade.
Why you'd still buy the tier below
Because the gap has narrowed. A current Fujitsu, Rinnai, Panasonic or LG inverter delivers most of the premium tier's efficiency, carries the same 5-year warranty, and the $400–$700 saved per room compounds fast in a multi-room house. Our honest read of the quote data: for a bedroom, the premium tier is rarely the rational choice; for the main living area, it usually is.
Not sure what size you're pricing? Run the 30-second size calculator, brand pricing only means something at the right kW.The spec sheet lines that actually matter
- Rated capacity at 35°C, and the derating curve. Ask what the unit delivers at 43°C; this is where tiers genuinely separate.
- Outdoor unit noise (dBA). Under 48dBA buys you strata approvals and neighbourly peace; premium units run 5–8dBA quieter than budget ones.
- Seasonal efficiency (AEER/ACOP) from the zoned label, the star badge alone hides the number that sets your power bill.
- Wi-Fi as standard vs. a $150+ dongle. Small thing, common surprise on the final invoice.
Picked a tier? The spread between installers quoting the same unit is routinely $400+, that's the negotiation the rankings can't do for you.
