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.
Most southern states like Florida, Louisiana, Arkansas, Mississippi, Alabama, Georgia, and South Carolina as well as parts of Texas all have a humid sub-tropical climate that would render an evaporative cooler useless. ** Do not purchase. NOT compatible. ** NO Returns.
