Evaporative Coolers are typically referred to as “Swamp Coolers,” a name they gained partly due to the way they cool. Evaporative Coolers use evaporating water to remove heat from the air. These units work best in very dry climates and are most popular in the southwest and desert areas. For an example on how Evaporative Coolers work, try holding your hand six inches from your face and blowing on it. Even though the air in your body is warmer than the air around you, your hand feels cool. This is because the moisture on your skin is evaporating – and when water evaporates it absorbs heat!

Evaporative coolers use evaporation to remove heat from the air, but they do it using water. Water flows over a media that air is pulled through, causing the water to evaporate and heat to be absorbed. These units are very common in the southwest, but require a very dry climate to work effectively.

Swamp coolers are normally located on the roof and can sometimes look like a “split system” outdoor unit, but have a water pipe feeding into them – which the others do not. A Swamp cooler must be drained for winter each year to prevent freezing.
