How Does a Swamp Cooler Work and Is It Right for You

A swamp cooler, also known as an evaporative cooler, is a type of cooling system that uses water to cool the air. It's a great alternative to traditional air conditioning, but is it right for you?

Swamp coolers work by drawing in hot outside air, which then passes through a wet pad that cools the air down. This process is called evaporation, and it's what makes the air feel cooler.

The cooled air is then circulated throughout your home, providing relief from the heat. Swamp coolers are especially effective in dry climates, where the air can hold more moisture.

In fact, swamp coolers can be up to 75% more efficient than traditional air conditioning systems in dry climates.
