What is AC Dye? When there are leaks in the Air Conditioning (AC) it is hard to pinpoint the leak. The Dye is actually a Fluorescent dye. The Technician uses a Violet or UV Light, they can see where the dye is glowing and are able to detect the leak or leaks. The refrigerant circulates and in time washes the dye out.
