Efficiency ratings of available AC units by regional metric

Notes

The standards, test procedures, temperatures bins and metrics used to evaluate efficiency ratings differ among countries, so ranges should not be compared across countries. SEER = Seasonal Energy Efficiency Ratio. CSPF = Cooling Seasonal Performance Factor. APF = Annual Performance Factor. COP = Coefficient of Performance. ISEER = Indian Seasonal Energy Efficiency Ratio. IPVL = Integrated Part Load Value.
