An air conditioner with cooling capacity lower than the required capacity for the space will not provide efficient cooling; and it shall be forced to operate the compressor continuously and energy consumption will be increased. An air conditioner with cooling capacity higher than the required capacity for the space will cool the room too quickly; and it turn the compressor on and off frequently. This will increase the energy consumption of your air conditioner. The room will be over-cooled and this will cause discomfort instead of comfort. Also, noise in the room smaller with respect to the capacity of the air conditioner will disturb you as the air conditioners with higher cooling capacity have higher noise levels. The heat insulation of the room that you used the air conditioner will increase your comfort and decrease the energy consumption; thus proper insulation of the heat loss gain points of the room is important. Moreover, the doors and windows of the room shall always be closed during the operation of the air conditioner. If the doors shall be kept open (as in shops or stores), use equipment that prevent hot or cold air flow from the outside as air curtains. [. . . ] Clean the dust prevention filters of your air conditioner regularly. As the blockage of the filters over time may prevent air flow, it will prevent you from obtaining the best performance from your air conditioner. This will also increase your energy consumption as it will constrain your air conditioner. Cleaning of the heat exchanger elements on the inner and outer units of the air conditioner is very important. [. . . ]
