Upon arrival system was not on Went into attic where air handler was located and noticed I didn't have any high voltage to unit at all. Asked home owner to show me to breaker panel Breaker for AC unit was tripped Flipped breaker and unit was running but had a really low Delta Moved to outdoor unit where I noticed outdoor disconnect was broken/damaged Went inside to flip breaker for condenser unit outside Checked capacitor- was in tolerance Checked contactor and was in good condition Gauged up and noticed suction line had low pressure but high line temp Which led me to diagnose low refrigerant and I started to leak search Found leaks in multiple locations on outdoor condenser both coils and lines Also let home owner know that downstairs unit has issue with condenser fan not turning on at times, which I noticed as I was diagnosing upstairs unit Recommended new condenser coil Recommended leak search and repair Recommended refrigerant refill Recommended new disconnect and whip A
