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.
Evaporative coolers are most effective in areas of low humidity and hot temperatures. They are not effective in humid climates or during rainy seasons. They are not as controllable as air conditioners, and can use between 3.5 and 10 gallons of water per hour, a consideration for use in areas with limited water supplies. The degree of humidity they deliver is a feature that distinguishes the two basic types of evaporative coolers.
