Thank you so much for that link! It was wildly pertinent to my life

I just moved into a new place this weekend. It has an addition not connected to central A/C. Instead, it has a little window unit, but also a (one hose) portable unit.

I was using the portable one, because I haven't had time to block the hole that runs outside (especially from critters climbing through). So I hoped that the air blowing out would discourage anything from climbing in

And now I will be taking the time to properly block the hole where the duct runs, because I immediately switched back to the window unit after watching that video

So thank you again! It's the first time I ever encountered a portable unit, so I knew nothing. And coincidentally, I just moved and had the option to use either the window unit or the portable

Just ridiculously relevant to my life as of this weekend! And ya just saved me money on electricity. You're awesome for that link my friend
