I Love Engineers but they don't know it all

Just finished a Walk through on a new school we did the Mechanical on (we are in the mid south so we build alot of schools) and we found one system for the common area/ hallway the unit was running fine with proper superheat and subcooling the temperature drop was 18 degrees the problem was they had us install the system in a closet in an unconditioned closet in the outside wall I did not notice it on the plans and during start up it never occurred to anyone until the space temp and humidity were an issue guess it happens to us all
