Spending money on cooling your home using air conditioning can be expensive. Air conditioning can account to as much as 40% in America to 70% in Asia of the energy consumed annually by an average household. Taking preventive measures to increase energy efficiency of air conditioners helps reduce energy bills. ���
In houses that have centralized air conditioning systems but where the family spends most of the time in one or two rooms, a split air conditioning system might be better. This will allow for localized cooling of one room only. Split air conditioners can also be used to complement the centralized air conditioner being used to cool only specific locations when cooling of the entire house is not necessary. They can be turned off when the central air-conditioning is switched on.
