No charge leak search is prepaid. Performed leak search searching for green UV dye that was installed with refrigerant on August 5, 2023. During today’s visit, I utilized UV light on both the indoor and outdoor portions of equipment with out success. Technician is not yet spotting the evidence of leakage. System is still cooling properly and performing well. This would suggest that potential leak is rather small.. Our office will schedule another return visit this time 3 to 4 weeks to resume fluorescent leak search.
