Looking at the RKM25ZVMG 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. Already have one installed and seeing a fault code? Look it up here, or Compare every registered model. More on Daikin systems, or read up on Common aircon problems.

Daikin RKM25ZVMG questions

Is the Daikin RKM25ZVMG the right size for my room?
The NEA register lists it at 2.45 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 RKM25ZVMG 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 RKM25ZVMG a single-split or multi-split system?
It is a single-split: one outdoor unit paired with one indoor unit, listed at 2.45 kW on the register. That makes it a one-room system, and the quote should name the paired indoor model.
Is the Daikin RKM25ZVMG still on the NEA register?
Yes. Its registration runs to 30 January 2028, more than four months after the 17 September 2026 snapshot this page is built from.
How efficient is the RKM25ZVMG at part load?
NEA records a part-load COP of 6.02 for the RKM25ZVMG. 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.
