Return to fix leaking coupling at condenser. All of the refrigerant was reclaimed from the system and the coupling at the condenser was cut out and a fixed. System was pressure tested and more leaks were found both at the branch box and at the 2nd floor air handlers. All of the connections that were leaking had couplings that had to be cut out and re flared. After repairs system was pressure tested again and system held pressure for 45 minutes to and hour. A vacummed was pulled and system was recharged with factory charge at 11lbs of 410a. Called tech support to check proper setting both at condenser and branch box dip switches were changed at outdoor condensers. System was monitored and is back up and running. Supply temperature is around 50-55 degrees repair is completed https://visionshare.xoi.io/?id=ms0ed132a1-575d-i184-39cb446782d2-uF83-4ac3c2bcbcfc
