Customer concerned about unit possible leaking Freon. Electronic leak search performed on evaporator coil, condenser coil, copper line set and copper fittings on split system. No leaks found in ac system. Unit is 3 yr old and was refilled 2 weeks ago. Checked refrigerant levels and check test start up components. Unit is properly charged with refrigerant and unit is cooling properly and drains at this time. If possible leaks are slow suggest uv dye detection on next pass if possible is persist. Suggest uv dye to locate any leak in ac system and future usage. Uv dye
