30 registered models
Fujitsu split systems, as the register lists them.
2 kW to 9.5 kW, across 8 of the eight capacity classes. Sold as 30 variants once colourways and trim levels are counted, which is why a retailer's catalogue looks bigger than the register does.
Quick answer
30 distinct Fujitsu wall-mounted single-phase reverse-cycle air conditioners are registered with the Australian Government's GEMS database, ranging from 2 kW to 9.5 kW and covering 8 of the eight capacity classes the Australian market advertises. Across the range the best annual cooling efficiency figure is AEER 4.97 and the best heating efficiency figure is ACOP 4.84, with the lowest declared indoor noise level at 55 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.
Fujitsu registers a compact range that nonetheless spans all eight capacity classes, so it competes at every size without carrying the number of variants the larger Japanese brands do. Its efficiency figures sit mid-field on the register for both cooling and heating. The practical consequence of a smaller range is fewer near-identical options to weigh up at each size, which some buyers find a relief and others find limiting — it depends whether you want the range narrowed for you or want to do the narrowing yourself.
Who this range suits
And who it doesn't.
A reasonable choice when the decision has already been narrowed by something else — a wholesaler relationship, an existing unit being matched, or a preference for keeping one brand across a house. What it is less suited to is a buyer optimising hard on a single metric, because the range does not top any of the three comparisons on this site. The compact range is also its practical advantage: fewer near-identical options at each size means less time spent deciding between units that differ by a rounding error.

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.

Fujitsu air conditioners — common questions
How many Fujitsu split systems are sold in Australia?
30 distinct Fujitsu wall-mounted single-phase reverse-cycle models are registered with the Australian Government's GEMS database, sold as 30 variants once colourways and trim levels are counted separately. They span 2 kW to 9.5 kW and cover 8 of the eight capacity classes the Australian market advertises.
Is Fujitsu good for heating in Melbourne?
The best annual heating efficiency figure across the Fujitsu range on the register is ACOP 4.84, against 4.97 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 Fujitsu air conditioner?
The lowest declared indoor sound level in the Fujitsu range is 55 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 Fujitsu 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.
