De'Longhi Insulated Hose Cover for Portable Air Conditioners (), DLSA003, 11"D x 15"W x 3"H, Gray

I have never written a review, I felt this product was worth a share.Background ; I work in a technical capacity , Electrical & Mechanical and had low expectations for this product.The Problem with many portable home AC units:The HOT air exhaust is just below the COLD air intake, the exhaust hose on my unit becomes almost too hot to the touch during operation, so the cold air intake is drawing heated air in that it must then cool to make you comfy. Additionally the HOT air exhaust duct going to your window or wall is radiating heat BACK into the room as well just like a heater. AC or Heater, which one is it?Is this good for your portable AC room cooling Efficiency: NO, it increases cost and impacts the ability of the unit to do it's desired function, COOL Your Room with a typical hose found on most.Results, two areas of interest:NOISE:I immediately noticed a reduction in the horrible noise and oscillation from my AC unit , I could not hold a Zoom call in my office it was so distracting with R2D2 ( my ac unit nick name) placed 10 Feet away.After the Sock install I was able to hold a Zoom call with no issues. I did not expect this at all. Noise down at least 30 percent on my unit I would ball park guess. Now that I think about it, all of the vibration / sound was being transmitted through the exhaust duct, and the ribs were vibrating acting like amplifiers also sending noise back into the room along with HEAT. It makes sense in reflection.COOLING:The unit cooled my room but not aggressively without the sock the previous summer, after the sock install the exhaust hose was only slightly warm to the touch, previously almost too hot to hang on too! I live in Desert with 120 deg heat in summer peak, All that heat was being transferred back into the room, like a dog chasing their tail. Wow, I don't know what they are using for insulation? It's thin but VERY effective on my unit.Now the room QUICKLY gets cold, the unit cycles on and off frequently, previously it just ran wide open and almost never cycled. What a difference. Definitely Noticeable and using less energy obviously as well.DOWN SIDE:If you could call it that, The Sock is not easy to install, it may take two people, It certainly did in my case. But this is why it was effective for noise in the end as it grips the hose reducing vibration and heat transmission.My install Approach: ( yours may vary)Remove hose end couplers , collapse hose fully and push the collapsed hose carefully to the center of the sock one person holding the sock one person pushing. Then gently expand one end of the collapsed hose a bit at a time inside the sock, then the other side until the hose is completely expanded, push the sock excess back over the hose to install the couplers (hose ends) or fold over as in my case. Install hose and fold back any excess to cover anything you can with the excess if available.There is no Give to the sock, so patience is key.On that note, the maximum bend radius will be slightly reduced due to the new cover, so if you are using very tight bends beware, 35 deg bend was possible for my install only, rough estimate. Certainly nothing beyond 45 deg seems possible in quick tests I performed.Overall:Astonished with my NEW ac unit, I am now wondering why these are not included on these types of AC from the manufacturer, I am very happy with my decision to take a chance.My experience: Quieter, Cooler, Less energy usage.

These things are a game changer for Any portable a/c unit with a 6 inch hose. I bought 2 because my air conditioner has an intake and an exhaust. The thought behind insulating the intake is that I dont want outside heat radiating through the tubing and into my room, thus making the a/c work harder and longer.These things are pricey, but it's all about the material they used. The quality is there, almost no perceptible heat emanating from exhaust tubing/duct with this thing on it.It works good.It aint easy to install these things, but some time and patience goes a long way. I found it easier to just keep the hose accordioned closed, shove it in this insulation, and then unaccodion it open inside the sleeve keeping it as straight and even as possible while stretching the hose out, and then manipulating it into the shape it needed to be while attached to the a/c unit and the window bracket panel adapter thing.--Side Note: I just used clear packing tape to keep the hose and their screw on adapters together to keep the hose duct from popping off, as these do indeed increase the rigidity of the duct and making it more difficult to manipulate into a shape without having the ends come off.

Ok, this was not the easiest to get onto the hose and was a little bit longer than the hose on my DeLonghi portable a/c. When I tried it on my other portable, an LG brand, it went on easier and fit the hose length exactly as it is intended to, meaning it works great when it’s matching size with the hose. The hose needed to be stretched fully to fit right. On either unit it did work great as far as insulation to stop the heat just radiating out of the entire length of the hose when it was on all the way. Seemed to stop any issue of heating the room from the exhaust hose and made both of the a/c units actually cool a room the size they claim on the unit. In the over 110 degree Phoenix heat of summer having this on the exhaust hose of the unit let them get the temp of the room between about 2 and 4 degrees. It’s hot enough that they never cycle off and it’s a few degrees warmer than you want inside, so that possible 4 degree lower feels great.A little expensive, which is a trade off for looks really, A much cheaper alternative is insulation for a round duct the same size, but this looks worlds better than silver bubble wrap any day,Minus one star because it was hard to use with an ac that was the same brand and was supposed to work with. (And the price is kinda high if you ask me, for what it is and does.)

Highly recommended. A number of reviewers mentioned it was difficult to install for a 6" duct. Our portable a/c has a smaller 5" duct, and the cover easily installed over it and there was ample room for a 90-degree bend. I can see how it might be a bit tight for a larger diameter 6" hose, though. After using the a/c with the cover, there is a noticeable difference in the cooling performance - before hand, there was a significant delay in cooling and we would always turn the set temperature down to compensate. Now, we can keep the a/c at a comfortable temperature and it reaches that threshold quickly and maintains it without significant fluctuation. Will definitely save us money in the long run! Also, a big bonus is that the cover blocks light coming in through the duct - we have a south-facing bedroom and light would always fill our duct (which is white plastic and not thick enough to block light) and light up the room, almost like a lantern. Bad for sleep quality if you like to sleep in, as I do. But this blocks out all of the light!
