Registered with the same figures as EuropAce ESAC18CUD. 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 ESAC21CUD 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 22 Jul 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 EuropAce systems, or read up on common aircon problems.
