Looking at the GWC12ATDXE-K6DNA3A/O for your home?

This is the outdoor half of a pair. The indoor unit is the half you live with, and it should be named before anything is agreed.

What to pin down before you commit

  • The paired indoor model number — the unit that mounts in the room
  • Whether the capacity suits that room, and how that was decided
  • What happens to the existing piping, drainage and bracket
  • Whether the old unit is being removed and disposed of

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.

GREE GWC12ATDXE-K6DNA3A/O questions

Is the GREE GWC12ATDXE-K6DNA3A/O the right size for my room?
The NEA register lists it at 3.47 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 5-tick rating on the GWC12ATDXE-K6DNA3A/O mean?
The NEA energy label rates it 5 of 5 green ticks, in the upper band for tested efficiency. Ticks describe energy use under the label test, not cooling strength, so compare it with units of the same size.
Is the GWC12ATDXE-K6DNA3A/O a single-split or multi-split system?
It is a single-split: one outdoor unit paired with one indoor unit, listed at 3.47 kW on the register. That makes it a one-room system, and the quote should name the paired indoor model.
Is the GREE GWC12ATDXE-K6DNA3A/O still on the NEA register?
Yes, but only until 27 November 2026 — within about 3 months of the 17 September 2026 snapshot, so confirm it is still on the register before relying on these figures.
How efficient is the GWC12ATDXE-K6DNA3A/O at part load?
NEA records a part-load COP of 6.39 for the GWC12ATDXE-K6DNA3A/O. Part-load efficiency describes how it performs when it is not running flat out, which is how it runs most of the time in a home.
