I just want too enjoy my AC when I'd like. Not feel like I spent ***$ on a ac works half way of how it should

Too have my AC feel like an ac ... I just recently but Ac unit that thousand square feet window units from home Depot and it's supposed to cool off at least one room that is in he's not even doing that anymore I would like to be able to Joy my hundred fifty dollars I spent on his AC you like the very first night when I fight because right now it's working as if I wasted $*** down the drain**I like it's be resolved by getting my money's worth out of a ac that I bought

I spent *** on a single room window unit and it can't even take that room cool like it supposed to

Sending a second window AC unit as a gift

I'm new here so I'm not sure what I'd expect but anyone would expect there ac to work the way it should

I've tried everything I could think of
