We’re not here to knock evaporative cooling—it’s an effective and efficient means to cool a living space in many homes. It requires little maintenance, and is well-suited for homes in dry and arid climates. But, evaporative cooling isn’t right for every home, and yours may be one.
For instance, they struggle when there is too much humidity in the air. Where a centralized air conditioner that uses refrigerant can bring down the temperature lower than the average homeowner would ever even need, an evaporative cooler has limitations and simply can’t lower the ambient temperature as much as a vapor-compression or refrigerant-based system.
