When you hear the term swamp cooler, you might be a bit confused. Also known as evaporative coolers, these are earth-friendly, affordable cooling options. Most effective in dry climates where humidity is 60% or below, they pull air over saturated rigid cooling pads that can reduce your room temperature up to 20 degrees. Our customers commonly use them in bedrooms, living rooms, garages, covered patios and porches, as well as in outdoor spaces like pool decks. 
Discover how they can help you beat searing summer heat without sky-high power bills, while maintaining an environmentally-friendly footprint.
Swamp Cooler Benefits
- Use significantly less energy than air conditioners, which makes them a great option during summer
- They’re natural cooling systems (using only a cooling pad, water, and a fan)
- Maintenance is pretty simple: You just need to add water and clean the reservoir & pads from time to time.
How Evaporative Swamp Coolers Work
Evaporative coolers are fresh air systems. Unlike traditional air conditioners, they do not use ozone-depleting refrigerants. The simple technology behind these machines is actually based on the naturally occurring process of evaporative cooling. The chill that you get after stepping out of the ocean or standing near a waterfall is the result of evaporative cooling. To cool your space more efficiently, swamp coolers use a fan to draw warm, stale air into the unit. For additional information on how swamp coolers work and top brands, check out the Evaporative Swamp Cooler Buying Guide.
As air passes over moistened pads, the cool, freshened air is distributed throughout your environment, alleviating dry conditions as well as reducing the ambient temperature, often as much as 20 degrees Fahrenheit. Since indoor swamp coolers need an open window or a door slightly opened, the ambient temperature in your room can feel four to six degrees cooler than the actual temperature thanks to consistently circulated air. Plus, the simple cooling process—requiring just water and air—makes evaporative cooling exceptionally eco-friendly.
