Likewise, the AC unit i got last year came with 2 pieces to connect but neither connecting piece can be adjusted in length so whatever gap i had i just left it and sure maybe it wasn't then operating at 100% but even at 90% or heck even 50% would have been significantly better than any fan.

Keep the original and install blackout behind it.

actually the tinfoil would block out the sun 100% and probably be lighter than his 2 layers of black.

u could just do 1 layer white, 1 layer tin foil, 1 layer black. bam.

pitch black, AND keeps prying signals out...

i just have a hose that goes to a huge sliding window

any tips or referrals on install to make it flush with the windows

I haven't tried this myself but perhaps this might help?

Anyone use these before? I'm thinking of getting an A/C soon as well and am also cursed with casement windows.

I guess I will give it a try for the price they're asking for. It got postive reviews on amazon and an A on fakespot.

On the other hand, I did get a quote for an acrylic glass sheet for my pretty standard size condo window and they wanted close to $200 for it so this seems like a pretty inexpensive option.
