Upon arrival tech was informed of bacterial buildup on supply vents in part department as well as employees in this are that are getting sick during the work week. Tech inspected system and found challenges at RTU4. Tech removed supply vents from supply line in parts room and found inside of duct to be clean and registers to be insulated. Tech found system to be running in cool mode set at 68. If system is running in cool mode most of the year this will cause supply registers to condensate being there is warm air mixing with supply registers. Also thermostat is located in electrical room conditioned by a mini split. Tech recommended cleaning all supply registers and installing a Plasma Pure Air Purifier to improve air quality in this area. Quoted $881.45 plus tax for installation of Plasma Pure Air. Quoted $180.62 to clean supply registers (each). Mr. Danny cleaned the supply registers. Tech relocated thermostat per customer request from electrical room to parts department. Tech tested

Tech found rtu 6 s#481D had a leak in evaporator tech added 2 leak freeze to each circuit system has 2 circuits and added 1lb of 410a to circuit 1. Tech let system run while working on others when tech returned tech did not pick up any more leaks with leak detection at this time. Rtu 7 s# 463D tech opened evaporator coil cabinet to perform leak search and picked up a major leak instantly. Upon further inspection tech found both compressor low of refrigerant enough to indicate leak was snot small tech does not believe leak freeze will help with this system. Rtu 8 s# 475D tech found circuit 1 completely void of refrigerant indicating leak is major and leak freeze will definitely not have any effect. Tech spoke with Daniel Informed him of new findings he instructed tech to not add any more leak freeze and he will go back to his leadership team and relay the findings and call back when they decide what they want proceed with.
