I currently have the Samsung unit (Max 2.5HP mini split Air Conditioner, AS24UUQ ). What are the energy efficient options to replace this. ( note: this is in a 220v country and i have no need for heating. Just AC )

The specs for the samsung:

Cooling Capacity (BTU/h) - 24,000
Energy Efficiency EER (Cooling, Btu/W) - 9.23
Rated Power Input (W) - 2,600
Noise Level (dBA) Indoor High/Low - 41 / 33

The best I have found has 24,000 btuh Cooling capacity with 12.5 EER. Is there anything better than this? ( with higher EER rating )
