A process for applying a fluorescent leak detection dye to a component of an air conditioning system. The process involves the steps of (i) providing a fluorescent dye that is solid at room temperature, (ii) exposing the dye to an elevated temperature to melt the dye into a liquid or flowable state, (iii) injecting, channeling, spraying or placing the flowable dye into or on a component or an HVAC or A/C system, (iv) allowing the dye to resolidify in or on the component, (v) attaching the component to the HVAC or A/C system, and (iv) dissolving the resolidified dye in a liquid/gas.
