ok seems like your getting partial answers and a epeen waving contest. if at 95 degrees and below your equipment does the job they are sized correctly and working properly. most equipment is designed to maintain 20 degree between outside and inside temp sounds like they are doing all they can do close outside air dampers if you can in a nursing home i would watch it. use water as needed and when the heat is over put everything back to proper settings. Good luck and take care in the heat
