Evaporative Cooling is an efficient solution for cooling your entire house providing fresh, clean cool air throughout your home. Evaporative cooling involves an external unit that sits on the roof and is connected by a series of ducting and outlets providing fresh air all throughout your house. An evaporative cooler creates cool air by drawing in fresh air, which is carried over moistened pads, which cools and filters the air. Compared to a refrigerated system, which dries out the air, evaporative cooling adds moisture to the air therefore improving comfort. Doors and windows can be left open to remove the hot air and create an open fresh environment inside your home.
