Is a 7 kW split system the right size for my space?
If your open-plan area is between about 45 and 60 m², probably. Under that, a 5 kW is cheaper and quieter. Past about 60 m², one wall unit struggles to throw air into the far corners, and two smaller heads or a ducted system start to make sense.
| Size | Standard room up to | Installed, typical | Cooling stars (median) | Indoor dB(A) (median) | Outdoor dB(A) (median) |
|---|---|---|---|---|---|
| 5.0 kW | about 42 m² | $2,100 to $3,300 | 3.5 | 60.0 | 63.0 |
| 7.1 kW | about 59 m² | $2,600 to $3,900 | 3.5 | 63.8 | 65.9 |
| 8.0 kW | about 67 m² | $3,000 to $4,300 | 3.0 | 64.6 | 67.2 |
Run your space through the size calculator before you settle on 7.1 kW. Oversizing a living room is common and it costs you twice.
What to check on a 7 kW split
- Power. A 7 kW unit often wants its own circuit. A dedicated circuit adds about $300 to $900, and an old switchboard that needs upgrading $1,000 to $3,500, so ask for it on the quote.
- Outdoor unit placement. The median outdoor sound level at this size is 65.9 dB(A). Keep it away from bedroom windows, yours and next door's.
- Stars. The best reverse cycle 7 kW units rate 4.5 cooling stars in the average zone and the median is 3.5. In a cold climate, the top heating rating is 2.5 stars, shared by ten models from Panasonic, Daikin and Westinghouse.
- Heating output. Most reverse cycle units in this class put out about 7 to 8 kW of heat, which is what matters in a big room in July.
For single-brand lists, see Daikin 7.1 kW and Mitsubishi Electric 7.1 kW.
How much does a 7 kW split system cost installed?
Usually about $2,600 to $3,900 supplied and installed in 2026, as an estimate for a standard single-storey job. A value brand sits at the bottom and a premium brand on a simple back-to-back wall usually sits in the middle. A second storey, a long pipe run, double brick or a new circuit adds to it.
Our split system cost guide explains the extras. Then get up to three local quotes. Ask each installer what area they assumed and whether they checked the switchboard; if they didn't ask about your windows, they guessed.
FAQ
7.1 kW split systems: common questions
What size room will a 7.1 kW air conditioner cool?
Up to about 59 m² of standard insulated room, about 50 m² with big west-facing glass, and about 42 m² with west glass and poor insulation. Past about 60 m² of open plan, price a multi-head or ducted system as well.
Is a 7 kW and a 7.1 kW split system the same size?
Near enough. The register has 55 models at 7.0 kW and 137 at 7.1 kW, with a few at 6.8 to 7.3. The difference in the room they cover is a square metre or two. Compare stars, noise and price instead.
Is one 7 kW split better than two smaller ones?
One unit is cheaper to buy and install. Two smaller units spread the air better in a long or L-shaped space and let you run only the end you're using. For an awkward shape, get up to three local quotes and ask for both to be priced.
How much does a 7.1 kW split system cost installed?
Typically $2,600 to $3,900 supplied and installed in 2026, depending on size and the job. 7.1 kW: $2,600 to $3,900. 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 7.1 kW split systems?
On the registered indoor sound level, the Kogan KASHSAC70T* (7 kW) is the quietest at 52.7 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 Braemar ASHV70D1S (7.1 kW) has the highest cooling rating here at 4.5 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 FTXM71AVMA leads at 2.5 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.
