Create Isolation Points
Cooling your entire home is a mammoth task and it is a move that will greatly increase your electricity bills. There is no need, however, to cool your entire property during the day if you will not be using all of it. For most people the vast majority of the home will be unused throughout the day, so paying large amounts to cool the whole property is unnecessary. By creating areas that can be isolated by closing an insulated door, you can make it so that you need only cool one room instead of trying to reduce the temperature of the other 90% of your home that you are not using.
