Consumer Council reveals 27% energy efficiency gap in Hong Kong ACs

A series of tests by Hong Kong's Consumer Council revealed that even among 'Grade 1' split-type air conditioners, energy efficiency can vary significantly, with the most efficient model saving up to 27.4% more energy annually than the least efficient. The council found similar disparities in heating efficiency, with differences reaching 10%, and some units failing to meet their claimed performance levels. These findings suggest that the current energy efficiency labeling standards may not adequately reflect real-world performance, prompting calls for updated grading systems to help consumers make better-informed choices and encourage manufacturers to improve quality control. Consumers were advised to examine detailed performance indicators, such as the Cooling and Heating Seasonal Performance Factors, rather than relying solely on energy labels. The council also highlighted the potential for significant household savings and reduced energy consumption if consumers select the most efficient models. The results underscore the need for both stricter standards and greater transparency in appliance labeling.
