Some of the areas in the United States rank as follows for evaporative cooler use:
South Western areas in California, Western Texas, Nevada, Arizona and New Mexico all have a typically hot dry climate that would be conducive to using an evaporative cooler. Compatible.
States like Utah, Wyoming, Montana, Idaho, Colorado, Washington and Oregon all have a semi-arid climate that an evaporative cooler would work well in, compatible providing the temperatures reach above eighty degrees.
Northern states from North Dakota to Maine
have
cooler summer climates. Although, not humid, the temperatures should
reach above eighty degrees for an evaporative cooler to have results. Semi-compatible.
States like Pennsylvania, Illinois, Delaware, Kentucky, and West Virginia all have humid climates that would cause an evaporative cooler to work less efficiently. Not very compatible. Purchase at your own risk. The warranty will be voided if shipped to these states.
Most southern states like Florida, Louisiana, Arkansas, Mississippi, Alabama, Georgia, and South Carolina all have a humid sub-tropical climate that would render an evaporative cooler useless. ** Do not purchase. NOT compatible. NOT RETURNABLE.
Damage Caused by Humid Environments In addition to an evaporative
cooler not functioning when used in improper climates, humid
environments can actually cause significant damage to an evaporative
cooler.
Although, regardless of location, an evaporative cooler
does require frequent maintenance, in humid environments the damage to
an evaporative cooler can be much more significant.
Humid
environments can cause the cooler to rust and erode prematurely.
Corrosion can cause the cooler to stop working as well, or can cause it
to stop working all together.
High humidity levels can cause the filters to grow mold faster, and can break down the mechanical parts of the cooler.
Using an evaporative cooler outside of the recommended areas can be
useless and expensive, since the cooler will require much more
maintenance than if it were to be used in a recommended environment. Shipments to the Not Compatible States are NOT RETURNABLE.
