Arrived on site and checked in with staff. Found building at 98 degrees in store. Went to roof and found only front system #1 moving any air. Found start capacitor melted and relay stuck open. All three windings of compressor open. Compressor and start components will need to be replaced. Moved to system 2 found void of refrigerant on last two maintenances. System currently found severely overcharged on roof with leaking evaporator coil. Recovered 4 pounds of refrigerant and was able to keep pressures low enough to run. Also found all safety switches bypassed on this system. Unsure of who had charged and bypassed wiring in this system. This is not the work of Ambient Edge. System would not cool with pressures running very high on liquid side and very low on suction side indicating severe restriction in liquid line of system. This is highly likely due to severe contamination of the refrigerant oil in the system due to sitting with air in lines for nearly a year. Site currently has no co
