Are Mitsubishi Electric split systems quiet?

How much does a Mitsubishi Electric split system cost installed?
A typical bedroom-size Mitsubishi Electric installs for around $1,700 to $2,400 in 2026 on a standard single-storey install, often a little under the equivalent Daikin quote. A 7.1 kW living-room unit is usually $2,600 to $3,900. Like Daikin, you get a five-year warranty and a wide service network.

FAQ
Mitsubishi Electric split system: common questions
What's the difference between MSZ-AP and MSZ-LN?
The AP is the mainstream series and covers 2.0 to 7.8 kW. The LN is the flagship, from 2.5 to 6.1 kW, with built-in Wi-Fi and a presence sensor. On the register, the AP holds the higher star ratings at the small sizes, so the LN premium pays for features. The AP is the more efficient choice at 2.5 and 3.5 kW.
Is Mitsubishi Electric the same as Mitsubishi Heavy Industries?
No. They are separate companies that share a heritage name, and both sell air conditioners in Australia. Mitsubishi Electric model codes start MSZ or MSY; Mitsubishi Heavy Industries wall splits mostly start SRK or DXK. Our comparison of the two explains the differences.
What does MSY mean on a Mitsubishi Electric air conditioner?
MSY is a cooling-only wall split. MSZ is reverse cycle, which heats as well. Unless you live somewhere that never gets cold, choose an MSZ model.
How much does a Mitsubishi Electric split system cost installed?
Typically $1,400 to $4,800 supplied and installed in 2026, depending on size and the job. 2.0 kW: $1,400 to $2,400; 2.5 kW: $1,500 to $2,500; 3.5 kW: $1,700 to $2,700; 5.0 kW: $2,100 to $3,300. 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 Mitsubishi Electric split system?
On the registered indoor sound level, the Mitsubishi Electric MSZ-GS25VFD2 (2.5 kW) is the quietest at 49.5 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 Mitsubishi Electric MSZ-AP25VG2 Series (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 Mitsubishi Electric MSZ-AP25VG Series leads at 3 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.
