Alec's terrific video about crappy one-hose "portable" air conditioners on Technology Connections...https://www.youtube.com/watch?v=_-mBeYC2KGcYou might cons...
TL;DW: It’s solid advice. Insulate the crap out of the space around the unit since the default spacers don’t seal/insulate well and let a lot of outside air mix in. He just goes above and beyond how most people would do that.
I thought it was going to be something wacky like stick a magnet on it or something, but he shows how to use a plastic sheet, spray foam, and a foam insulation panel to make a good seal (without the spray foam getting stuck to everything) that also looks good. I’ve used pool noodles in the past, but this seems like it would insulate even better.
