Upon arrival spoke with customer. Customer is stating that 1st floor condenser was/is making noise. Had customer put T-stat to call for cooling. Inspected 1st floor condenser. No noise/rattling is audible @ condenser. Remove condenser net covering to inspect fan blade and compressor. Remove condenser fan motor to check compressor windings. Windings checks out, meggohmmeter is reading good @ all windings. Check all other electrical components. Check pressures and temperatures. Stable, low side pressure 115psi / high side 285psi System is working normally and left operational @ this time. Check 2nd floor system pressures as a courtesy. Customer had 1lbs of R-410A refrigerant added early spring. Low side pressure 110psi / high side 275psi. Normal operation. Informed customer that once refrigerant is being added it’s an indication that the system has a leak. Upon next AC maintenance more steps maybe further required View visual findings from this job here - https://visionshare.xoi.io/?id=X
