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 MKC-4M27E 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 Midea systems. Common aircon problems have their own pages.
