Portable Air Conditioner Hose Cover Wrap, Universal Portable Ac Hose Insulation Sleeve, Fit 5" & 5.9" Diameter Air Conditioner Exhaust Hose Cover, Air Conditioner Parts & Accessories, 59" L

This a/c hose cover was easy to put on and really keeps the heat down inside my house. A must need for portable a/c owners.

The length we needed wasn't very long so I just folded pay off it over it's self, easy to install and works very well at keeping temps down

it is a tight fit but that is needed, you just have to pull it in tight to be able to fasten the velcro, it is thick enough and holds back about 85% of the heat on a hot 110f California day, I would buy again if needed.

From all the heat coming off the pipe to go outside it was making it so cooling my apartment was taking longer plus the AC couldn't keep it cooler in the apartment. This helped it made it so that on average it would keep the apartment 5 degrees cooler (on days 100F it would get it down to 72F before the I was lucky to get to 76F). So this worked out great for me. Just make sure you check your tube size.

I have 3 portable AC's. I bought this hose cover because it was cheaper than my previous covers. First of all, the strap is not velcro and is very flimsy. It has to be put on before you cover the hose. Second, when you push the Ac into place, and the hose curls, the velcro on the wrap gets gaps. I was able to fix this, but it's just a poor design. Also, to keep it tight, there were places the velcro would not stick. I suggest getting a wrap that slides over the hose. And make sure the straps are velcro, so you can adjust them.

I could feel the difference in temperature in the room within about 5 minutes. Only problem is it is much longer that I need. I was able to fold some up at the bottom. May not look super nice but it's so worth it

The cover is so thick the hose will not bend, which it must to connect window to air conditioner. In fact in trying to make it work both couplers broke away from the hose causing me many problems.

We bought this trying to eliminate the radiant heat that came off the exhaust hose going to the window. Prior to installing this, the standard vinyl accordion hose was emitting heat that permeated the small room where the unit was, so the AC unit was sucking in the hot air in a never-ending round robin of heat exchange. This fixed the issue and keeps that radiant heat from escaping, creating a noticeably cooler temperature in the room and doesn't tax the AC unit as much as when this sleeve wasn't installed. The bands that hold the sleeve in place could be a little more robust. As they tend to let the sleeve creep from the attachment points at both the exhaust port on the AC unit and the window when repositioning our unit to clean it.
