Abstract

Air conditioner (AC) is a vital device in room cooling systems widely used in tropical climate regions such as Indonesia. With high usage intensity, AC units are susceptible to performance degradation due to dirt accumulation, component damage, and lack of regular maintenance. This study aims to analyze the impact of comprehensive repair (overhaul) of indoor AC units on improving cooling effectiveness and energy consumption efficiency. Research methods include field observation, measurement of thermal parameters before and after repair, and comparative data analysis. The research object is a 1 HP split AC unit that has been operating for more than three years with identified damage symptoms. Components inspected and repaired include evaporator, blower fan, air filter, and condensate drainage system. The results showed that after overhaul, the air outlet temperature decreased by an average of 3.2°C, the coefficient of performance (COP) increased from 2.41 to 3.18, and electrical power consumption decreased by 12.7%. The conclusion of this study confirms that regular maintenance and proper overhaul procedures significantly improve the performance and energy efficiency of AC systems.
