Portable A/C's; improve with exhaust hose insulation

[petek]

I just received an exhaust hose insulation "blanket" off Amazon to fit onto my ancient portable a/c and it sure made a difference in how well it cools the room. I've always known about this inherent problem with these things but never bothered because it doesn't get used all that often. However the past few days have been miserable and it just wasn't cutting it in getting the room down past about 80 degs. A pretty cheap fix for around $20-$30 . I imagine just wrapping the hose with something else may works just as well if you're handy but right now I'm not handy LOL.

My friend did this to both of his single hose portable units, but he just used blankets he already had. One was kind of quilted. They made a difference by eliminating any noticeable heat radiating from the hose.

I have a single hose portable in my bedroom. It's directly under a window, so the hose only fans out where it makes a tight S bend. it's compressed everywhere else, and that extra density is enough to eliminate the heat factor.
