Yes, Hitachi air conditioners are still sold in Australia. The ownership behind the badge changed in 2025, which is where the confusion comes from, but the brand has a current local range and an active distributor.
Here is what changed. Hitachi's global air conditioning business had been a joint venture with Johnson Controls. On 1 August 2025 Bosch completed its purchase of that business, with a licence to use the Hitachi brand. The Australian site now says the products are manufactured and sold by Bosch Home Comfort Group.
Locally, Hitachi is distributed exclusively by Temperzone, based in Blacktown, Sydney. Temperzone has handled Hitachi here since 2009 and launched a new residential range, including the airHome wall splits and the airCore 700 ducted units, at the ARBS trade show in April 2026.
A bedroom-size Hitachi split usually installs for about $1,700 to $2,300 in 2026, with 7 kW living-room units around $2,600 to $3,500. That puts it in the middle tier with Toshiba and Carrier, under the Daikin and Mitsubishi Electric quotes.
The warranty is six years parts and labour on the current airHome and airCore ranges, one year more than the Japanese big three. The fine print is servicing: Temperzone's warranty can be voided if regular service is not done by an ARC-licensed installer. Budget for it, and keep the receipts. The easiest way to find a Hitachi dealer who will do both is to get up to three local quotes.

Is Hitachi air conditioning still sold in Australia?
Yes. Temperzone is Hitachi's exclusive Australian distributor, and the Hitachi Australian site lists a current residential range of wall splits, multi-split and ducted units. A new generation of residential products launched in April 2026.
The brand's owner changed. In 2025 Bosch bought the former Johnson Controls-Hitachi air conditioning business and took a licence for the Hitachi name. For you, the practical points are that the distributor and warranty holder in Australia is Temperzone, and that the warranty is current.
How much does a Hitachi split system cost installed?
| Size | Suits | Installed price |
|---|---|---|
| 2.5 kW | Bedroom or study to about 20 m² | $1,700 – $2,300 |
| 3.5 kW | Large bedroom or small living, 20–30 m² | $1,900 – $2,500 |
| 5.0 kW | Living area, 30–45 m² | $2,300 – $3,000 |
| 7.0 kW | Open-plan living, 45–65 m² | $2,600 – $3,500 |
Size the room first with the size calculator. For whole-home ducted, the ducted cost guide covers the $7,500 to $18,000 typical range.
Hitachi warranty in Australia
Temperzone's Australian warranty document, updated in September 2025, sets the terms. The current wall splits and ducted units get six years; some older lines and specialist units get five.
| Product | Parts and labour |
|---|---|
| airHome 400, 500 and 600 wall splits | 6 years |
| airCore 700 ducted, cassette and ceiling | 6 years |
| Multi-split (RAM), sold from 1 Oct 2024 | 6 years |
| Floor-mounted (RAF) | 5 years |
| Residential mini VRF | 5 years |
Hitachi ranges: airHome, airCore and multi-split
The airHome wall splits come in three lines, 400, 500 and 600, with the 500 listed as cooling only. The airCore 700 covers ducted, cassette and ceiling units for whole-home and open-plan jobs. The Multi Pro range and a residential mini VRF handle multi-room homes.
If you want heating from a wall split, check you are being quoted a reverse cycle model. A cooling-only unit in a Melbourne or Canberra bedroom is a costly mistake in July. When you get up to three local quotes, ask for the model number in writing.
Hitachi vs Toshiba, Carrier and Fujitsu
In the middle tier, Hitachi's six years sits between the five years of Fujitsu and the seven offered by Toshiba and Carrier. All four are trade brands with serious engineering behind them.
The deciding factor is local support. Fujitsu has the deepest network. Hitachi, Toshiba and Carrier are thinner, so the best of them for you is the one your installer fits and services most. Ask them directly, and get the warranty terms on the quote. Get up to three local quotes to compare.

- New residential range launched in Australia in April 2026

Watch-outs before you sign
- The brand changed hands in 2025. Hitachi air conditioning outside Japan is now made and sold by Bosch under a brand licence
- Warranty requires regular servicing by an ARC-licensed technician. Skip the service and you can void it
- Trade-only and not widely stocked, so regional service needs checking
- Older warranty pages online still show superseded terms. Go by Temperzone's current document
Our verdict
A credible mid-tier choice through the right dealer, with a better warranty than the Japanese big three. Ask your installer how they service it, because the warranty depends on it.
Whatever the badge, sizing and install quality decide how it feels to live with. Check your postcode's rebate and get quotes from up to three licensed local installers to compare.
FAQ
Hitachi questions
Is Hitachi still selling air conditioners in Australia?
Yes. Temperzone is the exclusive Australian distributor and launched a new Hitachi residential range in April 2026. Since August 2025 the products outside Japan are made and sold by Bosch under a Hitachi brand licence.
Who owns Hitachi air conditioning now?
Bosch completed its purchase of the former Johnson Controls-Hitachi air conditioning business on 1 August 2025 and uses the Hitachi brand under licence. Hitachi Ltd kept its residential air conditioning business in Japan.
