Will this device reduce or eliminate the moaning noise that comes from my Goodman 3 1/2 ton compressor?

This is a "startup only" device, it will reduce startup current of the compressor during the first second or two, then is disconnected from the circuit.

No but a compresor blanket might and check all of the spots on compesor that might be rubbing tighten all the screws,nuts,etc.

If the noise is only on startup it could help. If it makes the noise after it starts this will not help. All this device does is help make starting the compressor easier

Not sure on the moaning, will cerainly allow a steady current flow to your A/C unit making starting easier.

If this is a system with internal fans throughout the piping the foam may reduce a small amount of noise probably not worth it for your application. We had an enclosure in a studio that had a venting system and we lined the inside of the enclosure with the foam as well and you could barely hear the cooking fans, computers, and other rack gear that may have created a low end hum. I don't know if that answers your question or not hope it helps.

It's actually not bad. Yes, it's vibrating so it generates noise but I've had compressors that are so loud you have to raise your voice to talk while standing next to them. This one, however, is not that loud

It colors the tone when engaged, and also adds a bit of noise. Most compressors do. But adding a clean power supply or a noise suppressor will fix that. If I recall correctly, a low output from the pedal results in low noise.

There's a part you can twist near the nozzle, while I'm not sure of the exact function of this part, just twist that and it should fix the noise.

I can tell a difference when the vacuum is on, but it is not very loud. I would say it adds a little but not a whole lot of noise. Make sure the red screw that is there for shipping is removed...if your system is very noisey you may want to contact support.

Well, I guess that all depends on your perspective on noisy. I run it in my shop, and we barely notice it. If it were in a library, you might call it slightly noisy. It does sort of "vapor" out a fog of oil from the vent, but there again, nothing significant. I've never noticed any sort of film around it. Mine does not leak anything. As it works, it does pull some oil out of the system. So, the oil level in the compressor will go up, and you will have to drain that off every so often. I also change that oil about every 10 uses, for longevity.

My machine has developed the same noise. The old machine I had also had a rubbing noise at the flywheel. I have used this machine heavily for the last six months.It still runs fine. I use music to mask the noise. Its not noticable.

Not noticeably different than other portable air compressers. Probably slightly louder than a hairdryer

Mine is a different sounding fridge, but not really louder, I believe it is mostly fan noise not compressor noise. But ... make sure that you have at least 2" of air gap in the back. It is such a big unit it is tempting to push it back as far as you can. The better air flow you have over the back the less sound you hear.

Ours makes a small cyclic hum. You can hear it. It doesn't bother me, but everyone has different tolerances.

I'm not sure if it's the official way to do it but if you've already pressured it pull off the gas line and stick a flat head screwdriver into the inner circle on your post (like letting air out of a bike tire). Should hear a nice hiss...let off as much as you want/need and you should be good to go.

No I do not have an answer without more info, or a more specific identification of the compressor. The model number provided didn't match any current products I could find.

As I turn it from 1 to 3, it revs up to a fairly load sound. Both of our Holmes Humidifers were the same. I think that if yours is quiet on three, something is wrong.

The reason you are hearing the hum is because your transformer plates are slightly loose. The metal plates in the core are laminated and can become separated, you may be able to reduce or eliminate the hum by painting a varnish or shelac onto the core and letting it "soak in". I would suggest several thin coats to do the job. The metal core itself can be loose and vibrate as a whole too so you may need to seal that up the plastic bobbin that the copper windings are wound on. Otherwise if all else fails this unit is quiet, at least the one I got is. You may also try insulating between the transformer and the joist if yours is mountable that way. Hope that helps.

Don't know because mine is not noisy. Maybe you should call the owner/manufacturer and ask. He is very helpful and nice to do business with.

Probably not. This product is for fluid leakage. It doesn't modify the lubricity of the fluid to reduce bearing noise, which is the first suspect, but not the only one, for a whine.
