33 systems, all brands
That is about $5 a month more than the cheapest system its size, or roughly $610 over ten years — before you weigh purchase price, which often runs the other way.
It is not an inefficient unit, though. It sits at the larger end of its size group, so it works harder for the same rating. On efficiency alone it ranks 7 of 33 — middle of the pack.
Cheaper systems the same size
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 MKM85VVMG for your home?
This is the outdoor unit only, and on a multi-split it is shared across rooms. What decides the job is what goes inside them.
What to pin down before you commit
- One indoor model number per room, not just a room count
- The capacity of each indoor unit, and which room it serves
- Whether every room can run at once at full output, or the system is sized for typical use
- What happens to the existing piping and drainage, and whether it is being reused
A multi-split can be built many ways, and the register carries one figure per registration. The running cost above is for the configuration NEA tested — yours depends on how many indoor units end up on it and how hard they work.
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. Look up a fault code if one is already installed. Compare every registered model, or read more on Daikin systems. Common aircon problems have their own pages.
