Upon my arrival in Coupland I performed the UV leak search and was unable to locate a leak, it was too windy to attempt the leak detector outside but did use it inside. I searched both indoor and outdoor with the UV light. I added more leak dye to the system and recharged with 1.5 pounds of refrigerant so they system can run and hoped present the leak with the leak dye. When I depressed the Schrader I did not get any signs of UV leak dye within the system before adding more to it. Will need to schedule a return in 1-2 weeks to perform the leak search again.
