About Hitachi
Hitachi was founded in 1910 in the town of Hitachi, Ibaraki, Japan, originally as the electrical repair arm of the Kuhara Mining Company, becoming an independent company under the Hitachi name in 1920. Today it's one of Japan's largest industrial conglomerates, with air conditioning one of many divisions across a business spanning rail, energy, construction machinery and digital systems.
In Australia and New Zealand, Hitachi air conditioners have been exclusively distributed since 2009 through an alliance with Temperzone, a long-established local HVAC manufacturer — Temperzone handles Hitachi's local warranty support, spare parts and technical assistance, and the two brands continue to be shown together at Australian industry events. Globally, Hitachi's residential and light-commercial air conditioning business operated for a period as the Johnson Controls-Hitachi joint venture before this business was acquired by Bosch in 2025; Hitachi-branded products continue to be sold under licensing arrangements in various markets. Voltas installs and services Hitachi systems as part of our regular multi-brand work across Adelaide — we are not an authorised Hitachi or Temperzone dealer.
Hitachi Air Conditioners: Background & Adelaide-Relevant Range
Hitachi's air conditioning range in Australia sits inside a distribution structure that's a little different from most other Japanese brands: rather than Hitachi running its own local sales and service arm, the Australian and New Zealand market has been served since 2009 by Temperzone under an exclusive alliance, with Temperzone providing the local engineering, service and warranty backbone for Hitachi-branded equipment alongside Temperzone's own product line. This arrangement remains current, with Temperzone and Hitachi continuing to be exhibited jointly at Australian HVAC industry events.
The Hitachi range available through this arrangement covers wall-mounted split systems, multi-split systems for multi-room homes, and ducted split systems for whole-home coverage, alongside commercial and light-commercial options. Hitachi's current residential range runs on R32 refrigerant, which the company has actively promoted globally as part of its move away from higher-GWP gases.
It's also worth knowing that Hitachi's global residential and light-commercial HVAC business (previously the Johnson Controls-Hitachi joint venture) was acquired by Bosch in a completed 2025 transaction; Hitachi branding continues under licensing arrangements in a number of markets. This corporate history sits behind the products rather than changing how the Adelaide-relevant range functions day to day, and the local Temperzone distribution and support relationship in Australia has continued unaffected. For Adelaide properties, Hitachi via Temperzone tends to suit buyers wanting a Japanese-engineered product backed by a well-established local technical and parts network.

Get a Free QuoteWhich Hitachi System Is Right for Your Property?
Hitachi's Australian range, distributed through Temperzone, spans wall-mounted split systems through to multi-split and ducted split options — the right choice depends on room layout and how many zones you need to cover.
Wall-Mounted Split Systems
Hitachi's core residential single-room split range, covering standard cooling and heating for bedrooms and living areas.
Multi-Split Systems
One outdoor condenser servicing multiple indoor heads (Hitachi's RAM multi-split range runs on R32), suited to homes needing several rooms covered without extra outdoor units.
Ducted Split Systems
Whole-home ducted air conditioning for concealed, zoned coverage across larger properties.
Commercial & Light Commercial Systems
Higher-capacity equipment for offices, shops and light-industrial applications, supplied through the same Temperzone-Hitachi network.
Wall-mounted splits suit single rooms and standard Adelaide bedrooms; multi-split suits homes with several rooms needing coverage from limited outdoor space; and ducted split systems suit larger homes wanting a fully concealed, whole-house solution. We'll assess your property in person before recommending a tier or capacity.
Hitachi vs Other Brands — Which Is Better, and Why
Independent Australian HVAC sources generally position Hitachi as a solid, Japanese-engineered option with the practical advantage of a well-established local distribution and service network via Temperzone. Here's how it's commonly compared against two other brands we also install.
Daikin
Daikin operates its own direct Australian sales, manufacturing and service arm, whereas Hitachi's Australian presence runs through its exclusive Temperzone distribution alliance — both models can work well, but it's worth understanding who actually handles warranty and parts locally before you compare pricing.
Mitsubishi Heavy Industries
Both Hitachi and Mitsubishi Heavy Industries are large Japanese industrial conglomerates for whom air conditioning is one division among many, and both rely on dedicated local distribution partners in Australia rather than a standalone national retail-facing HVAC business — a useful similarity when comparing local support structures.
These are general, independently-sourced market positions, not a single definitive verdict — the right brand for your property depends on your budget, room layout, noise sensitivity, and whether you need a split system or ducted comfort. A Voltas property audit (below) gives you a specific recommendation rather than a generic one.

General HVAC maintenance knowledge applies to Hitachi systems just as it does to any brand — here's what we see most often, plus a few brand-specific notes from independent reviews and our own service experience.
- Reduced airflow or cooling usually traced to a dirty filter or outdoor coil — the single most common and most preventable service call across every brand.
- Fault codes on the indoor unit or wired controller Hitachi units display diagnostic codes; noting the exact code before calling a technician speeds up diagnosis considerably.
- Remote or wall controller pairing issues occasionally reported after power outages, usually resolved by re-syncing the controller to the indoor unit.
- Condensate drainage issues blocked or poorly sloped drain lines causing water leaks from the indoor unit — a common issue on any brand, particularly after a rushed or amateur installation.
- Refrigerant leaks on R32 systems, a licensed technician is legally required to handle any gas work — never attempt to top up or diagnose refrigerant issues yourself. For genuine Hitachi parts and warranty claims, work ultimately routes through the Temperzone network.
A routine Hitachi split-system service (filter clean, coil check, drain clear, gas pressure check) typically takes 30–60 minutes per indoor unit, with ducted and multi-split systems taking longer depending on the number of zones. We recommend an annual service for most Adelaide households, or every six months for systems used heavily through summer or in dusty environments.
Not Sure Hitachi Is Right for You? Book a Voltas Property Audit
Brand choice is only half the decision — sizing, placement, and ductwork design usually matter more to your actual comfort and running costs than the badge on the unit.
1. On-Site Assessment
We measure room sizes, window orientation, insulation, ceiling access, and existing electrical capacity — the real inputs that determine what capacity and system type will actually perform well.
2. Load & Capacity Calculation
Rather than guessing a kW figure, we calculate the cooling/heating load your specific rooms need, so you're not paying for an oversized system or stuck with an undersized one that runs constantly.
3. Brand & Model Shortlist
Based on your budget, noise tolerance, property type, and whether Hitachi or another brand genuinely suits the job better, we shortlist two or three realistic options — with honest trade-offs explained.
4. Fixed, Itemised Quote
You get a clear price for supply and installation before anything is booked in — no surprise costs, no pressure to commit on the spot.

Book Your Free Property AuditHitachi Warranty, Standards & What to Check Before You Buy
What the Hitachi/Temperzone Australian distribution network states, so you can weigh it up before buying.
Warranty
Temperzone, Hitachi's exclusive Australian and New Zealand distributor, generally backs Hitachi domestic (residential) products with a 5-year parts and labour warranty, though Temperzone's own published documentation notes that exact warranty periods can vary by model and application type. We'd recommend confirming the specific warranty term for your chosen model directly with Temperzone or your supplying dealer before purchase, since terms and any registration requirements can change.
Refrigerant
Hitachi's current residential range in Australia, including its multi-split line, runs on R32 refrigerant, which Hitachi has promoted globally as a lower-global-warming-potential alternative to the R410A it replaced. Australia's HFC phase-down under DCCEEW runs through to 2036 and regulates the import of bulk refrigerant gas rather than pre-charged equipment, so it doesn't prevent you buying or installing an R32 Hitachi system today — it affects the broader supply and cost of refrigerant gas over time.
Australian Standards
Every installation must comply with AS/NZS 3000 (the Wiring Rules) and is completed by our A-Class electricians and licensed HVAC technicians. Energy performance is labelled under the Australian Government's GEMS Zoned Energy Rating scheme — check the specific model's current label for its star rating in your climate zone before buying.

Is Hitachi still owned by Hitachi globally?

How long does a Hitachi air conditioner installation take?
A single wall-split installation is typically completed within half a day; multi-split and ducted systems take longer depending on the number of indoor units and complexity of the job.
