Amana PBH093G35CB 9,300 BTU Through-the-Wall Air Conditioner: in White

This unit can’t even keep my work room at 61f. It doesn’t even turn on when it’s 72f in my work room. I’ve lost thousands of dollars 💵 in product the past yr, because this unit can’t keep a simple room at the temp it’s set for. Temp in room can not go above 67f & it does just about everyday because this doesn’t turn on 80% of the time 😡😡😡😡😡😡😡😡
