The best selection of residential air conditioner require consumers to justify the advantages of any potential model over other potential models. The payback period (PP) analysis between possible potential models can be used as a indicator for consumers to justify which type and model they should choose. This report presents an analysis to investigate the PP between inverter and non-inverter split type air-conditioners for household application. The selected air conditioners used in this study are from 1.5 horse power inverter and non-inverter types spilt unit, residential air conditioner. The mathematical model of economic analysis is developed based on proposed model developed by previous researches. The operating cost for each air conditioner are determined from the data provided by the manufacturer. In this analysis, the increment of percentage on energy saving, hours of daily operation and decrement of interest rate reduce the PP of inverter type split unit air conditioner compared to non-inverter type. It is found that an inverter type air conditioner with highest energy saving of 65% has shortest PP of only 3.42 years, followed by an inverter air-conditioner with highest operating time of 12 hours per day (3.75 years), and an inverter air-conditioner with lowest interest rate of 1% (4.33 years). Meanwhile, the service work at the middle of unit’s life time (month 90) has no effect on its PP. In short, the percentage of energy saving has dominant effect on PP followed by the effect of operating hours per day and rate of interest.
