Air conditioning can account for 60% to 70% of the total cost of electricity during the summer months. Consumers pay a lot of attention to electricity costs as well as comfort in their homes. For most people it is a balance between comfort and overall cost that dictates the setting for your air conditioner. Another factor is that women seem to like the AC temperature set lower, while many men find it too cold especially as they get older. Bottom line is that the best setting for your air conditioner is one where you are comfortable in your own home and you are not worried about the cost of the electricity being used. However there are ways to use your Air conditioning efficiently, live comfortably and minimize your total cost of electricity.
What’s the best setting for your Air Conditioner
The basic rules is if it is not running, then it is not costing you money. Let’s assume you set the AC at a particular temperature. Can you increase the temperature by one or two degrees? Can you close window blinds to reduce thermal warming from the sun? Can you set the thermostat higher during the day when you are not at home? Can you take advantage of lower electrical rates in the evenings vs. during the day if offered in your area? Did you locate your outdoor unit in a shady spot that is clear of plants and other obstructions? Have you cleaned all filters?
If you have answered yes to these questions, then you are probably doing everything you can to decrease the cost of air conditioning short of just turning it off completely. Your AC costs will not be lower if you maintain the same temperature all day long whether you are at home or not. Cold homes act as a heat sink and will attract heat from outside. Set your AC at a reasonable temperature during the day to avoid huge electricity bills during the summer months.
