Dale Gibson of Gibson Air Systems in Jamaica, Virginia offers his new invention, a black spotted filtration system that slips directly onto a cooling or heating coil!… Just kidding folks, this cooling coil with a ¾” blanket of yuck. This cruddy coil was pulled from a system two weeks after the building owner paid $250.00 to have his “friend in the business” clean the coil.

The cooling system had so much refrigerant added over previous years that the coil finally exploded from excessive pressure. Thanks to Jonathan Miller, service tech and dirty coil model for expressing his delight with this extraordinary find.
