Noise harvester and my air conditioner

Power Components
1

It’s getting warmer and warmer where I live and we started using the air conditioner,
Funny thing is that earlier this year I bought the PS Audio noise harvester,
Didn’t expect much of it and it actually did not show noticeable improvement to the sound. It didn’t light up very frequently either, so I concluded that either it is just not doing anything or I am really lucky to have very clean power to begin with (I am running a dedicated line to my HiFi)

BUT

Now that we turned on the air conditioner it started flashing like crazy :slight_smile:
I have a few air conditioners at home, but only 1 in particular causes the noise harvester to flash like crazy. I know that this particular unit is different, it is an AC Inverter type of air conditioner (supposed to invert AC to varying DC and therefore be more energy efficient, or something in that area of explanation). So I guess this AC inversion process is kicking back some nasties back to the main,

I would really like to prevent this leakage at the source.
Is there any EMI filter I can install in-line to the air conditioner plug that will help reduce this effect?
I have no way to actually measure the noise to know it’s frequency or amplitude.

Will something like this help?

There are a lot of quiet air conditioners now available on the market. You don’t need to take hastle in this matter. Or if you want to do this, you can connect with hvaclifehack, which always delivers the best in hvac systems.

One inexpensive way to help clean up EMI problems on your home’s ac lines is to get a sheet of Stillpoints ERS cloth and cut it to size covering the circuit breakers in your breaker box. I just tape the top edge of the ERS sheet with duct tape and let it drape over the breakers. Even though I have a PS Audio Stellar regenerator, a Shunyata conditioner, and High Fidelity Cables magnetic power conditioners extensively used in my two systems, the use of ERS cloth on the breaker box made a noticeable improvement in background noise reduction. I’ve also been applying wraps of ERS cloth to the power cables of other EMI noise generators like the refrigerators, washer/driers, and modem power supplies.

That is good to know !
