That is about $5 a month more than the cheapest system its size, or roughly $630 over ten years — before you weigh purchase price, which often runs the other way.

Registered with the same figures as EuropAce EGAC12E3. On paper they are the same machine.

Cheaper systems the same size

Systems around the same size that cost less to run, closest in size first. Cheaper to run is not the same as the better buy — purchase price, indoor units, and how well it is installed all sit outside these figures.

Looking at the SACN 6283 for your home?

This is a plug-in appliance rather than an installed system, so there is little to settle beyond the unit itself.

What to pin down before you commit

  • Where the exhaust hose runs, which decides most of how well it performs
  • Whether the room is realistically within its range

Figures are NEA energy-label records checked 17 Sept 2026, priced at the label's 27¢/kWh assumption. Your own bill depends on how you actually use it. Compare every registered model. More on SONA systems, or read up on Common aircon problems.

SONA SACN 6283 questions

Is the SONA SACN 6283 the right size for my room?
The NEA register lists it at 3.4 kW of cooling capacity. Match that against the room's size and heat load rather than assuming one capacity suits every room, and have the installer confirm it before the unit is chosen.
What does the 1-tick rating on the SACN 6283 mean?
The NEA energy label rates it 1 of 5 green ticks. That sits in the lower part of the scale, so higher-rated units of the same size use less energy under the label test — check the same-size comparisons on this page.
What kind of aircon is the SACN 6283?
It is a portable unit, listed at 3.4 kW on the register, a plug-in appliance rather than an installed split system. There is no outdoor half to mount, so the exhaust route is the main installation detail.
Is the SONA SACN 6283 still on the NEA register?
Yes. Its registration runs to 6 April 2028, more than four months after the 17 September 2026 snapshot this page is built from.
How efficient is the SACN 6283 at part load?
The register does not list a part-load COP for the SONA SACN 6283, but it records a full-load COP of 3.02. That figure only describes efficiency when the unit runs at full output.
