"It is true that operating air conditioners mean high electricity bills but there is no reason to worry because there are effective ways to curb this high electricity bill.The first thing that needs to be kept in mind is to set the temperatures properly. In the summer it should be set at 24 degrees centigrade and during the winters it must be set at 19 degrees. This is helpful because for every degree of heating or cooling that you sacrifice you are actually saving on dollars.Operating the AC only during the day and opening the windows and doors during the evening so that the natural air can come in is an effective way to stay cool yet keeping the electricity bills under check.Spaces like the attic need to be cooled with ceiling fans instead of lowering the temperature of the air conditioner constantly. The fans will circulate the chilled air throughout the rooms and there will not be any need to lower the temperature of the air conditioner further.Ductwork should be inspected properly so that the conditioned air does not escape through the leaks. If the ducts are insulated the AC will have to work less hard thus keeping the electricity bills under control.Lastly, the right kind of maintenance is the key to keep your electricity bills low even if you operate air conditioner. One of the integral aspects of maintenance is to change the air filters once in a month."
