I kludged some hose insulation last year by wrapping with roll insulation and then making a sleeve out of fleece, but it was homely and still noisy. Installed this yesterday and the noise reduction is surprising. It also looks...pretty nice, actually. Also a lot more idiotproof than I anticipated, despite having to cut it because I didn't need the entire length. Note that this is about 6.25" diameter on the inside, so you can't just pop it on the back of the AC; you need to keep a 6-12" stub of your original hose attached to the AC, slip this hose over the stub, then affix in place.

I was previously using a standard/cheap aluminum wire ducting material which radiated a significant amount of heat back into the room. This insulated duct not only reduces that duct heat radiation to almost nothing, but keeps my portable LG 9k BTU unit cooling my office far better than before as a result of it. Only noise I hear is the LG A/C compressor and fan. As you can see in the picture the ducting is running up to the drop ceiling tile, and the previously used aluminum duct is in front of the LG unit. I'm very pleased with the results of this Hon & Guan insulated duct,

I love the concept, but was very hard to install on my 6” couplers. I had to use a bunch of duct tape to keep in place. The insulation is very nice and the light doesn’t leak out. Overall I’m quite pleased.

The stock hoses for my portable (two-hose!) air conditioner had disintegrated, and I've long been considering buying a set of insulated hoses for it ever since I bought the unit. I'm honestly surprised that they were not insulated at all out of the box. As such, I bought two of these hoses in 6"x8'. Installing them onto the original hose adapters was a bit of a task, entailing very liberal application of duct tape. This done, I connected them up and powered the unit up. I did not buy these hoses with the intent of being quiet, but I was honestly and pleasantly surprised by how much quieter the condenser side fan was now. I can barely hear it anymore, and it quickly subsides under the sound of the compressor once pressure builds. With the original hoses, it was easily the loudest part of the entire air conditioner. I cannot measure the thermal performance directly versus the original hoses, due to the original hoses having disintegrated years ago as of me writing this review. However, I can definitely say that, before, it was actually hot behind the unit. With these, it's significantly cooler, and the unit's performance has significantly improved. It can now actually cool my garage! Something it used to struggle with. The hoses have also survived from a durability standpoint significantly better than the original plastic hoses. Although they ARE a little less convenient to store when the air conditioner's not in use thanks to their bulk. That's the only "negative", other than the admittedly improvised installation, that I can even say about them. Final Answer: If you have a portable air conditioner and use it with any regularity, upgrade it to insulated hose(s) now. You will not regret it.

Duct was good, only issue was that clamp rings were too small, so 2 each really was only one ring each as you have to double them up to fit over the insulated duct. The other minor issue that you can't do much about is that the thicker duct can be difficult to install on some fans as they don't have much clearance between the fan exit and the ceiling drywall. That was only an issue because the fans were already installed and I was just replacing the ducts though.

I purchased the 6" x 8' hose to install on my portable air conditioner. Anyone that has one, you know the heat that radiates from the included hose is very high and inefficient. Although this hose does not look the prettiest, it is an absolute must for replacing the included hose on your conditioner. Running my air conditioner prior to this hose, I could only keep the room about 8 degrees below outside temps. After installing this hose, the room cools MUCH FASTER, and also gets about another 6 degrees cooler compared to the outside. An almost double cooling efficiency. This hose is room temp to touch, and feels like it contains >90% of the heat my previous hose allowed through. In addition, the air conditioner unit runs much quieter due to the sound insulation this hose provides. At least 30% of the noise from your AC is coming from the turbulent air flow rattling around inside the hard crimps of your standard plastic hose. If you do purchase this hose for your AC, make sure to get a size slightly larger than the diameter of your input/output, so you can fix the hose to the exterior of the couplings with a good duct tape. Honestly, if you try to fix the hose to the interior, it seems like you might end up rupturing the lining and exposing the fiberglass inside, which would be bad. I used the larger size and it secures nicely in place with a good 3" wide duct tape.

I use this hose to help get more heat into my tent. During very cold camping a non insulated hose loses too much heat. We were heating two tents at one time in 14 degrees and due to heat loss in the hose it was a struggle to keep up. With this hose we don’t have any issues as I can’t feel that the hose is warm from the outside.
