42 registered models
Mitsubishi Electric split systems, as the register lists them.
2 kW to 10 kW, across 8 of the eight capacity classes. Sold as 196 variants once colourways and trim levels are counted, which is why a retailer's catalogue looks bigger than the register does.
Quick answer
42 distinct Mitsubishi Electric wall-mounted single-phase reverse-cycle air conditioners are registered with the Australian Government's GEMS database, ranging from 2 kW to 10 kW and covering 8 of the eight capacity classes the Australian market advertises. Across the range the best annual cooling efficiency figure is AEER 5.07 and the best heating efficiency figure is ACOP 5.3, with the lowest declared indoor noise level at 49.5 dB. Thunderman Electrical and Air Conditioning Services installs split systems across Greater Melbourne under ARCtick certification with electrical work by REC 28523, and advises on selection using the register rather than manufacturer marketing.
What the register says about this range
The honest summary.
Mitsubishi Electric is the other Mitsubishi, and separate from Mitsubishi Heavy Industries in every practical sense. It carries fewer distinct registered models than the row count in a retailer's catalogue suggests, because a large share of its listings are colourway and generation variants of the same registered unit — the designer LN range alone is registered in black, red and silver under a single number. Across the eight capacity classes it is present in all of them, with efficiency figures in the upper part of the field for cooling and mid-field for heating.
Who this range suits
And who it doesn't.
Worth a look if the indoor unit has to live somewhere visible, because this is the range that puts real effort into how the head looks — the designer models are registered in several finishes precisely because they are sold on appearance as much as performance. That is a legitimate reason to choose a unit; a wall-mounted head is a permanent object in a room people live in. Just be aware the finish is what varies between those registrations, not the performance: black, red and silver share one registration number and one set of figures.

Cooling and heating are rated capacity. AEER andACOP are the annual efficiency figures for cooling and heating — higher is cheaper to run. Stars are shown as cooling / heating for a mixed climate zone, which is the one Melbourne sits in. Indoor noise is the manufacturer's declared sound level for the indoor unit. Every figure is as registered with the Australian Government's GEMS register, and the registration number is there so you can look it up yourself.

Mitsubishi Electric air conditioners — common questions
How many Mitsubishi Electric split systems are sold in Australia?
42 distinct Mitsubishi Electric wall-mounted single-phase reverse-cycle models are registered with the Australian Government's GEMS database, sold as 196 variants once colourways and trim levels are counted separately. They span 2 kW to 10 kW and cover 8 of the eight capacity classes the Australian market advertises.
Is Mitsubishi Electric good for heating in Melbourne?
The best annual heating efficiency figure across the Mitsubishi Electric range on the register is ACOP 5.3, against 5.07 for cooling (AEER). In Melbourne the heating figure carries more weight, because a reverse-cycle system here runs for warmth far more of the year than for cooling. Those are the range's best figures, not typical ones — individual models vary, which is why the tables above list them separately rather than giving the brand a single score.
What is the quietest Mitsubishi Electric air conditioner?
The lowest declared indoor sound level in the Mitsubishi Electric range is 49.5 dB. Declared figures are measured by the manufacturer at a stated fan speed, so they compare fairly against other brands' declared figures but will not match what you measure in a room — mounting position and the surfaces around the unit change that considerably.
Does Thunderman install Mitsubishi Electric air conditioners?
Yiannis is ARCtick certified, which is what handling refrigerant legally requires, and installs split systems across Greater Melbourne regardless of brand. Which ranges he can supply directly depends on wholesaler arrangements, so the honest answer is to ask — and if a brand you want is one he cannot supply well, he will say so rather than talk you into something else. Electrical work is carried out under REC 28523.
