In the CA desert, in its drought conditions and potential water usage limitations, the regulators have suggested AC should replace evaporative coolers.
Evaporative coolers are economical in low humidity, high heat applications. They don't work well in high humidity locations like Florida. A real air conditioner that draws out the moisture at the evaporator installed in the air plenum. A real air conditioner works fine in low humidity/high heat as well.
My location in southeast Idaho is high desert. Very low humidity/dew points. That is one of the key reasons I relocated. Even San Diego was too humid for my comfort.
