I had a $300 portable AC and it was loud regardless of how you set it up, now I have a $700 one and it's crazy quiet [spoiler]for portable ac standards[/spoiler]. You can't really make those things quiet, but I was surprised to learn that more money actually brings some serious value in there. 

I love cool air so much that I don't care about noise or bills, it's just too much of an upside to care about drawbacks. Especially for 30c+ heat, this thing is just saving lives
