The air cooling unit has been giving off stale and lukewarm air during Memorial Day weekend when the temperature and humidity reached well over 90 degrees. After complaining, the Co-op finally posted memorandum on 5/31/2011 claiming to set up a cooling room during the day only on Wednesday June 1st and from 10AM-10PM on Thursday June 2, because the cooled air system will not be turned on until June 3rd. My senior mother and her neighbors had to endure the scorching apartment heat and weather for another week. This is so typical of the Penn South-no regard!
