What is a Swamp Cooler?
A swamp cooler is a type of cooling system that uses evaporation to cool the air, which is perfect for Florida's humid climate.
It works by drawing in hot outside air, passing it through a water-soaked pad, and then blowing the cooled air into your home. This process can lower the temperature by as much as 20-30 degrees.
The water-soaked pad is the key to a swamp cooler's effectiveness, and it's designed to be refilled regularly to maintain optimal performance.

How it Works
A swamp cooler is a simple yet effective way to cool down a home or room. It works by circulating warm air into the unit, where it comes into contact with moist, sponge-like pads.
These pads are key to the cooling process, as they help to cool down the warm air by releasing moisture into it. As the air passes through the pads, it picks up moisture and is cooled down.
The cooled and moistened air is then circulated throughout the space, providing a refreshing and cooling breeze. This process is efficient and can be a cost-effective alternative to traditional air conditioning systems.
