Swamp Cooler Average Costs. 1  A whole house swamp cooler might cost $1,500 to $4,500 installed. 2  Two-stage evaporative coolers, which produce less in-home humidity by cooling the air before it passes through the moist pads, are quite a bit costlier than the one-stage coolers described above.
All portable swamp coolers have CFM ratings, which makes it easy for you to figure out if a unit will be powerful enough to cool a given area. To calculate your ideal CFM range, first determine how many cubic feet you need to cool. This is done by multiplying an areaâs square footage by the ceiling height.
