Compare 3 quotes for my houseA Daikin 2.5 kW split is the bedroom unit most people have in mind when they say they want "a Daikin". It cools a standard insulated room of up to about 20 m², which covers most bedrooms and studies.
The register lists 25 Daikin wall splits at 2.5 kW: 20 reverse cycle and 5 cooling only. They all look much alike on a retailer's page, but the star ratings run from 2.5 to 5.5 depending on the model. That gap is the whole reason to read the model number before you sign.

Every model on the Energy Rating register marked available in Australia. Stars are the zoned label for the average climate zone (average zone); indoor noise is the registered sound power level, measured the same way for every model.

Which Daikin 2.5 kW split system should I buy?
Group them by the start of the indoor code and the differences are clear. Noise barely changes across the range. Efficiency changes a lot.
| Indoor code | Type | Cooling stars, average zone | Heating stars, cold zone | Indoor dB(A) |
|---|---|---|---|---|
| FTXM25 | Reverse cycle | 5.5 | 3.0 to 3.5 | 57 |
| FTXV25 | Reverse cycle | 5.0 to 5.5 | 2.5 to 3.0 | 58 |
| FTXF25 | Reverse cycle | 4.0 | 2.0 | 56 |
| FTXJ25 | Reverse cycle | 3.5 | 2.5 | 56 |
| DTXF25 | Reverse cycle | 2.5 | 1.5 | 56 |
| FTKM25 | Cooling only | 5.0 to 5.5 | none | 56 to 58 |
| FTKF25 | Cooling only | 2.5 to 3.0 | none | 56 |
For a bedroom you'll use most nights, the FTXM25 has the best ratings in both cooling and cold-climate heating. The FTXF25 is the sensible budget pick. Ask the installer which of Daikin's series names each code belongs to; our Daikin review explains the Lite, Cora, Zena and Alira X ranges.
How quiet is a Daikin 2.5 kW split system?
Every Daikin 2.5 kW on the register sits between 56 and 58 dB(A) indoors. That figure is sound power, measured the same way for every brand, and it is a little above the 54.5 median for all 2.5 kW units. The much lower numbers in brochures are sound pressure at the lowest fan speed, a different measurement. For a light sleeper, compare the register figures across brands in the quietest split systems ranking.
How much does a Daikin 2.5 kW split system cost installed?
A 2.5 kW split costs about $1,500 to $2,500 installed in 2026 on a standard single-storey install, and a Daikin usually lands in the upper half of that band. Like-for-like, expect a few hundred dollars over a mid-tier brand. The premium buys Daikin's dealer network and five-year warranty.
A long pipe run, an upstairs bedroom or a new circuit adds to it. Get up to three local quotes and make sure each names the exact indoor code, so an FTXM isn't being compared with a DTXF.
FAQ
Daikin 2.5 kW split systems: common questions
Is a Daikin 2.5 kW big enough for a bedroom?
Yes, for a normal bedroom up to about 20 m². With big west-facing windows it tops out nearer 18 m², and with poor insulation as well about 15 m². For a bigger main bedroom, look at the Daikin 3.5 kW instead.
What's the difference between the Daikin FTXM25 and FTXF25?
Both are 2.5 kW reverse cycle wall splits. On the register the FTXM25 rates 5.5 cooling stars in the average zone and up to 3.5 heating stars in the cold zone; the FTXF25 rates 4 and 2. The FTXM costs more and saves more to run, which pays off in a room you use a lot.
Should I get a Daikin 2.5 kW or 3.5 kW?
Measure the room. Under about 20 m² with average sun, the 2.5 kW is enough and rates better. Over that, or with afternoon sun, take the 3.5 kW. The size calculator settles it in a minute. Then get up to three local quotes on the size you land on.
How much does a Daikin 2.5 kW split system cost installed?
Typically $1,500 to $2,500 supplied and installed in 2026, depending on size and the job. 2.5 kW: $1,500 to $2,500. Pipe runs, a new circuit or a second storey add to it. Get up to three local quotes for your actual job.
Which is the quietest Daikin 2.5 kW split systems?
On the registered indoor sound level, the Daikin DTXF25T2VMA (2.5 kW) is the quietest at 56 dB(A). Compare within the same size: bigger units are louder. See the quietest split systems ranking.
Which is the most energy efficient?
For the average climate zone, the Daikin FTKM25QVMA (2.5 kW) has the highest cooling rating here at 5.5 stars. Star ratings on the zoned label run to 10, and a star is worth more in a hot zone than a mild one. For cold-climate heating, the Daikin FTXM25AVMA leads at 3.5 stars.
What size split system do I need?
Roughly 2.5 kW for a bedroom, 3.5 kW for a large bedroom or small living room, and 5 to 7.1 kW for open-plan living. West glass and poor insulation push it up. Use the size calculator for your room.
