SBUHD Universal-Fit Air Conditioner Compressor Sound Blanket Wrap (#0421A)

Works very well. Went from having to close doors in my house to not hear the compressor, to barely being able to hear it with the doors open. Wish I had taken decibel readings before I installed it, but the noise reduction is significant. It's not silent and the method ofinstallation does matter. I think people aren't sealing the covering up as much as they should. The velcro straps are there to hold it together while you wrap duct tape all around it and seal every gap. Gaps let the sound ride the air out, so don't be stingy on the tape. Very happy I finally (FINALLY) got around to doing this. Took about an hour to install because I also cleaned the coils while everything was opened up.

Brand new 4T Trane 454B system and the compressor sounded so stinking loud. Trane says 72-81dB is ok (seriously WTF Trane). Purchased this, install was easy & now I literally cannot hear my AC compressor running anymore while I am in the house. I 100% recommend this and would recommend this to anyone that doesn’t like excessive and needless AC compressor noise.

Compressor is about half as loud now. And there might have been some frequencies that were rattling windows that are now blocked; the window isn’t rattling anymore. Daughter can sleep better. Product doesn’t match the picture. It’s black not gray. And it will be all squished/deformed when you get it fit right, not nice looking like in the picture. It must be sized for a pretty big compressor. I was gonna say the velcro straps don’t work too well when the top part gets pulled tight around the compressor. They are way too long for a Trane 2 ton unit. But I should have just cut them shorter. The bottom of my AC unit had big grooves in the bas; I stuffed them with pipe insulation. A good bit of sound is still getting out somehow. Not sure if its from the compressor pipe holes or holes in the bottom or gaps from somewhere else. Need some sort of gap detector… Anyways it works pretty well.

Going by the app on my phone this product drops the AC noise by 3/5 dB. I'll give it 3 stars because I wanted more sound deadening but definitely helps some. Will update if something catches on fire, hasn't yet.

Worked as described! I saw about a 6db drop from unit startup (equivalent to about a 75% volume drop) and a 3db drop from steady state for the unit. This was measured from 3ft away from the condenser. As others noted it is fairly large, so I had to pull pretty hard on the velcro straps to make sure it wasn't touching the internal fins. The unit delivered is also black as opposed to light gray. I'll report back on how it holds up over time. The only potential downside is that because it is large, getting behind it to clean the fins may be a bit more challenging with a hose.

It was a fairly easy install The blanket itself does not seem very thick. All of the above is really in the end not very important, the big question is if the blanket makes a difference in noise level. In that assessment the subjective impression is important, but I also tried to make measurements with the dB meter on my watch. Subjectively I am not 100% sure if there is any difference. Our compressor is a scroll type. I think some of the high frequency sounds may be a tiny bit muffled to a lower frequency. Inside the house I really cannot tell a difference before and after. I looked at the dB measurements on my watch: Outside before (right next to the A/C unit 71-72 dB. After installation of the sound blanket: 70-71dB Inside the house before: 50-51dB Inside the house after: 49-51dB For me the blanket made no perceivable difference. I think my noise is primarily from the fan of the unit. Purchase and installation were a waste of time. Hope I don’t have problems returning this as others had described. Overall I am very disappointed. Can’t understand the positive reviews by others.

A Goodman single stage heat pump I installed recently has been working well, but the sound is really annoying! Much louder than our two stage Goodman. Wondered how the two stage suppressed the sound and found it came with the custom fit sound blanket installed. Looked up online and found this AC compressor sound blanket on Amazon (of course). Ordered Thursday & got it Saturday. Installed in about twenty minutes with a helper to balance fan assembly off to the side. There are four long Velcro straps (left and right in upper and lower positions) the base assembly. You will need to trim to length since the left and right straps mate to the same 12” length of hooks. Just pull tight and cut at mid point to leave room for mating strap. Note: I also applied several lengths of super tough and strong Gorilla Duct tape to ensure a tight fit and as backup to straps. Looked very good but of course I didn’t take a picture. Result: works pretty well! I amno longer distracted by the sound of the unit and while the sound is a bit still louder than our two stage, the level is overall acceptable. Didn’t measure decibel level because who cares, it’s the “oh wow, that’s not so annoying anymore” result I care about. Per one of the other reviewers, I created movie which illustrates the before and after sounds levels.

Very happy with the results
