If there are masters of cooling, it must be the Arizonans. They deal with this weather system for most of the year, but they know that overworking the air conditioner means reduced service life and hefty utility bills. This is why air conditioners are almost never alone in beating the Arizona heat; they have Phoenix shutters to help out.
Window treatments like Chandler shutters and shades are low-cost contributions to the cooling effort, whether at home or the office. Along with other types of insulation, even a house without an air conditioning system can stay cool under the unforgiving Arizona heat. This is because the shutters, with heat-protective coating, are designed to keep outside heat out.
