Note the line running North to South through the
mid-section of the USA. This line defines the area that typically
separates the use of Evaporative Coolers from Air Conditioning.
Evaporative Cooling is used in many areas West of the Line
except during periods of high humidity. Air Conditioning is recommended
East of the Line as humidity levels are normally too high for
effective operation of Evaporative Cooling. There are of course
always some exceptions, therefore check Frequently
Asked Questions. (Click on map for line detail)
