Self Diagnostics that include audible alarm and LCD visual display readout

The KwiKool’s Flagship Iceberg Series of portable air and water-cooled air conditioners are quick and easy to run with its “plug and play” technology and they top the competition in its small size, big performance, and tons of features.

From its hi-tech microprocessor controls and self-diagnostics to the long list of standard features (most of which are not even available in other brands), the KwiKool Iceberg Series outperforms, outlasts, and out features other portables and all at a price that is comparable to the no-frills products that are available.
