Evaporative Swamp Coolers: Save Money and Cool Large Areas by Using Evaporative Cooling

Did you know that evaporative coolers cost about one-quarter as much energy as air conditioning? If you live in a low-humidity area, evaporative coolers offer a natural, energy-efficient way to stay comfortable. These air coolers are also known as "swamp coolers" and cool outdoor air by passing it over water-soaked pads. This cooled air is then directed into a room or home while warm air is pushed out.

Maintaining Your Evaporative Cooler

Some consumers are turned off by evaporative swamp coolers because they think they're more difficult to maintain than air conditioners. While swamp coolers do require periodic maintenance, this usually only involves draning and cleaning the unit in order to prevent sediment build-up.

However, also keep in mind that the more frequently you use your swamp cooler, the more maintenace it will need. In hot, dry climates, you'll probably be using the unit several hours a day. If this is the case, remember to check the unit's filters, reservoir, pump, and pads regularly. Doing so will ensure proper cooling and years of hassle-free operation.

For more information on swamp coolers, see our air cooler buying guide.
