Installed prices are estimated 2026 ranges for a standard back-to-back install, not quotes. Your installer confirms the number on the invoice.
Daikin is the badge installers name first. Mitsubishi Heavy Industries is the one they quietly recommend when the budget matters. Both are Japanese, both carry five-year parts and labour warranties, and both make splits that are still running long after the paint on the eaves needs redoing.
The difference on quote day is price. A comparable MHI split routinely comes in one to three hundred dollars under Daikin for the same capacity. That is not a quality discount. MHI spends far less on marketing here, and the saving reaches you.
Owners seem to agree. Mitsubishi Heavy Industries won Canstar Blue's Most Satisfied Customers award for installed air conditioners in 2025 and again in 2026. Daikin answers with the biggest dealer network in the country and the most brand trust, which matters most outside the capitals.
On noise, the bedroom units are level on paper. Daikin's Alira X, Zena and Cora and MHI's Avanti Plus all list 19 dB(A) at their lowest 2.5 kW cooling setting. Neither will keep you awake if it is sized and placed properly.
Our lean: in a capital city, take the MHI saving. In a regional town where the only authorised agent for miles is a Daikin dealer, or for whole-home ducted in a new build, Daikin earns its premium. Either way, get up to three local quotes with both brands priced for the same room.
Is Daikin better than Mitsubishi Heavy Industries?
Not on the things that break. Both brands build premium inverter splits with excellent reliability records in Australian conditions, and both back them with five years parts and labour. Blindfolded, most installers could not tell you which unit they were servicing by its behaviour.
Daikin is better on reach: more dealers, more service agents, more new-build ducted experience, and the most recognisable badge. MHI is better on value: similar engineering for noticeably less, and the strongest customer satisfaction results of any brand in recent Canstar Blue surveys.
Daikin vs MHI price, by size
| Size | Suits | Daikin | Mitsubishi Heavy Industries |
|---|---|---|---|
| 2.5 kW | Bedroom to about 20 m² | $1,900 – $2,500 | $1,800 – $2,400 |
| 3.5 kW | Large bedroom or small living | $2,000 – $2,700 | $1,900 – $2,600 |
| 5.0 kW | Living area, 30–45 m² | $2,300 – $3,300 | $2,200 – $3,100 |
| 7.0 kW | Open-plan living, 45–65 m² | $2,600 – $3,900 | $2,600 – $3,700 |
Across a house with three or four splits, the MHI saving can reach the cost of another unit. Size each room with the size calculator, then get up to three local quotes with both brands at the same capacities.
Warranty and service: where the real difference is
Daikin's warranty card gives five years parts and labour on residential split, multi-split and ducted systems, from the original owner's purchase date. MHIAA's residential terms give five years on parts, labour and the compressor, and its FAQ says the warranty is void unless an ARCtick-licensed installer does the job.
So the paperwork is a draw. The difference is who turns up. Daikin has the deepest service network in Australia. MHI's is good in the capitals and thinner in smaller regional centres. Before you sign for MHI outside a capital, ask the installer who does MHI warranty work locally and how long their last claim took. If you do not have an installer yet, get up to three local quotes and ask each the same question.
- Use a licensed installer with an ARCtick licence. Both warranties depend on it.
- Keep the invoice with the model and serial numbers.
- Neither warranty covers poor installation, so the installer's own workmanship guarantee matters too.
Which is quieter, Daikin or MHI?
At the bedroom size, they are level on paper. Daikin lists 19 dB(A) on quiet for its 2.5 kW Alira X, Zena and Cora models in cooling. MHI lists 19 dB(A) at the lowest setting for the 2.5 kW Avanti Plus.
Real-world quiet comes from sizing and placement: a unit big enough to idle rather than race, and an outdoor unit that is not under your bedroom window. Our quiet bedroom picks cover what to ask for.
Daikin vs MHI for ducted
For whole-home ducted, Daikin is the more common quote. More dealers carry it, its zoning controls are well known to new-build crews, and the network depth matters more when the system is in your roof for fifteen years.
MHI makes good ducted units and can quote well, but fewer installers push them. If you are pricing ducted, get Daikin and at least one other brand such as MHI or ActronAir quoted with identical zones in writing. The ducted cost guide covers the $7,500 to $18,000 typical range.
Which should you buy?
- Capital city, split systems, want value: Mitsubishi Heavy Industries.
- Regional town with a Daikin dealer down the road and no MHI agent: Daikin.
- Whole-home ducted in a new build: start with Daikin, and make a second brand compete.
- Quotes within fifty dollars: Daikin, for the network and resale reassurance.
- Unsure: get up to three local quotes with both brands itemised on each, and ask which they would put in their own house.

The verdict
In the capitals, MHI gives you premium Japanese quality for less. Regionally, or for ducted, Daikin's network is worth the extra. Get both quoted for the same room and let the itemised numbers decide.
Get both quoted properly: same capacity, same install spec, itemised. Start with the rebate on your postcode, then get up to three licensed local installers to quote the same job so you can compare.
FAQ
Common questions
Is Daikin better than Mitsubishi Heavy Industries?
Not on quality or reliability, where the two are very close. Daikin has the deeper service network and stronger brand recognition; MHI is usually one to three hundred dollars cheaper for the same capacity and has topped recent Canstar Blue customer satisfaction ratings.
Are Mitsubishi Heavy Industries air conditioners good?
Yes. MHI builds premium Japanese splits with five-year parts, labour and compressor warranties in Australia, and won Canstar Blue's Most Satisfied Customers award for installed air conditioners in 2025 and 2026. Check local service coverage if you are outside a capital.
Which is cheaper, Daikin or MHI?
MHI, usually. In 2026 a 2.5 kW MHI split typically installs for about $1,800 to $2,400, against $1,900 to $2,500 for Daikin. The gap widens at larger sizes and across multiple rooms.
What's the difference between Mitsubishi and Mitsubishi Heavy Industries?
They are separate Japanese companies. Mitsubishi Electric is the household electronics brand; Mitsubishi Heavy Industries builds ships, turbines and aerospace systems as well as air conditioners. Both sell good splits in Australia. See our MHI vs Mitsubishi Electric comparison.
Which is quieter, Daikin or Mitsubishi Heavy Industries?
At 2.5 kW, both list 19 dB(A) at their lowest cooling setting, so the spec sheets do not separate them. Correct sizing and where the outdoor unit goes make more difference than the badge.
Is Daikin a good brand?
Yes. Daikin is the benchmark premium brand in Australia, with the deepest dealer and service network and a five-year parts and labour warranty. You pay a little more for the badge, which is worth it most in regional areas and for ducted.
