A swamp cooler, also known as an evaporative cooler, is a cost-effective and eco-friendly way to keep indoor and outdoor spaces cool and fresh. This type of cooler is often used to cool down covered porches, warehouses, living rooms, garages, and more. Swamp coolers use evaporation to cool the air. The fan will take the warm air and it will pass through the water-moistened cooling pads. Evaporative coolers are capable of cooling up the air up to 24 degrees Fahrenheit. If you’ve been using your evaporative coolers for a long time, you should know how to make swamp cooler more efficient. Here are a few simple tips on how you can do it.
