A swamp cooler is a water-based HVAC system that uses less energy than a traditional air conditioner. An effective, greener choice to consider, it does have some limitations. It can only cool an area in relation to its own size.

If you are thinking about installing a swamp cooler, seek the advice of a professional HVAC contractor or installer. The units are bulky and hard to handle alone. Getting a professional installer will save time and trouble.
