Abstract
Air conditioner (AC) is a machine that is used to cool the air by circulating refrigerant gas in a pipe that is pressed and sucked by the compressor. Refrigerant gas a material that is circulated, this material is volatile and can change its shape, in the form liquid and gas. The heat in the condenser pipe comes from refrigerant gas which is pressed by the compressor so that the material becomes is minimized, so that the pressure in the evaporator pipe to cool down the method used is descriptive qualitative method. Methods for solving problems by studying in depth. The formulation of the problem from this research is what factors cause the AC not to cool, efforts to fix cause of the AC not cooling and overcome what can cause the air conditioner to not cool and maintenance on the AC system. The purpose of the research is to find out and overcome what can cause the air conditioner to not cool and how to treat the air conditioner. Regular AC maintenance at KN. Kumba shows that regular maintenance can prevent damage to the AC system and make AC use more durable. Based on research, the problems that most often occur are dirty evaporator, dirty condenser, dirty filter, and lack of freon. From the results of this study concluded that the cause of the AC is not cold. Leaks in AC pipes dirty condenser and evaporator, lack of freon. The repair it is by welding the leaking pipe, cleaning the condenser and evaporator and adding freon to the installation. Keywords : Air conditioner, maintenance, repair.
