Help keep your house cool with a window-mounted evaporative cooler

Installing an Evaporative Cooler

Evaporative coolers, also known as swamp coolers, work by pulling in fresh outside air through moist pads, where it is cooled by evaporation and circulated through the house by a large blower. These coolers typically are used where the air is hot and humidity low.

This guide outlines the steps for installing a window-mounted evaporative cooler.
