Help keep your house cool with a window-mounted evaporative cooler
Evaporative coolers, also known as swamp coolers, pull in fresh outside air through moist pads, where it is then 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 needed to install a window swamp cooler.
Tip: Before learning how to install a swamp cooler, you must first select the best one for your needs. There are many kinds available, including roof swamp coolers, side draft evaporative coolers, down draft evaporative coolers, whole-house coolers and small space options. See our evaporative coolers buying guide for help in deciding if a window-mounted cooler is a good fit for your home.
What You Need

• Place the cooler in the window, resting the vent on the support assembly.
• Attach the cooler to the brackets as directed by the manufacturer’s instructions.
• Tap into the water line and run a water supply line to the cooler.
• Install a cut-off valve that you can easily drain in the winter.
• Attach a hose to the overflow drain line of the cooler and run the hose on the ground, well away from the foundation.
