As a doen lover I want every item. The prices… not so much. Any recs for quality pieces that aren’t so $$$

For those of us who live in the beautiful Vintage apartments that make LA so special we sadly don’t have air-conditioning or parking for that matter. This heat has become unbearable. All of my windows are front doors. I need any and all recommendations for good AC units or portable unit units because I can’t out anything in the windows. Help!
