At approximately 8:00 AM there was a mechanical failure with an EMD Air Handler Unit 1,2,4,&5 which caused temperatures to very and with little to no flow to some of the floors. At this time Facilities Engineering is in the process of recovering the Air Handler Units. A follow-up message will be delivered once all mechanical systems and room pressures are working in a normal manner. (update on EMD AHU’S 1, 4, &5 have been repaired). Air Handler 3 serves 2,3, & 4th floors with heating and cooling and has air flow. EMD 2 is still down and OUR FACILITIES CREW IS STILL working on it.
