Fort Hood

So I'm pregnant and I have a 2 and 3 year old, my family and I have been in Fort Hood a year exactly and our AC has gone out 7 times in the past 2 months and the upstairs doesn't stay cool at all and my 3 year old always sweats at night. I was wondering if anyone put an AC unit in there kids room and if its allowed because the next time our AC goes out I really would at least have my kids sleep comfortably at night.
