If you’re looking for a cost-effective, more environmentally friendly way to cool your home, an evaporative cooler is a great option. Also known as “swamp coolers,” evaporative coolers are designed not for humid conditions but rather for arid, dry, hot climates such as those found in the American Southwest and West. Evaporative coolers fill a unique niche among climate-controlling appliances, offering efficient cooling in a package that is easier to install and less expensive overall.
