Advantages

Less expensive to install

Estimated cost for installation is about half that of central refrigerated air conditioning.

Less expensive to operateEstimated cost of operation is 1/4 that of refrigerated air.

Power consumption is limited to the fan and water pump vs. compressors, pumps, and blowers.

Ease of Maintenance

The only two mechanical parts in most basic evaporative coolers are the fan motor and the water pump, both of which can be repaired for very little and often by a mechanically able homeowner.

Evaporative cooling increases humidity, which, in dry climates, may improve the breathability of the air.
