Not sure where you are located, but most people have low toleration for overly dry air. Running an air conditioner in a dry place like Arizona or California will only make it drier. Running it in a humid place like Florida or Virginia makes the humidity level tolerable. When I lived in California, we used an evaporative cooler most times of the year. Only the hottest days did we turn to AC. But here in the east coast, the evaporative coolers would probably be mostly useless.
