James helped diagnose RTU 11 and show Brad and hunter mini splits and walk through on cleanings. Brad and Hunter still in site performing maintenance. RTU11 needs new suction port someone in the past has damaged this port and makes it non serviceable. System is definitely low on r-410a and made laura aware due to temp split and suction line temperature. Ran a leak test on system but could not pin point a leak. Made Laura aware we need new service port on suction side and then can service/ charge system and further leak test.
