Are you saying the window units are loud? They are a lot less annoying than the built in AC. i cannot hear my neighbors window unit most of the time, but my other neighbors built in drive me crazy. Like having a waterfall next door. Makes me have to pee all night long.
Do you neighbor a favor and get a window unit!
AAww..... just get some diapers. Pretend you're sleeping next to a tropeeical waterfall!
