A/C Condenser Whirring sound

THis could be strictly because I am at home all of the time now and didn't notice it before. one of my air conditioner condensers is making a little more noise that the other. If you listen to it, there are two noise patterns. One would seem to be the fan motor and a second undulates at a slightly different frequency. This is the one that seems to transmit though the house. This is not loud or anything indicating an imminent failure but not normal and is not present in the similar AC unit right next to it.

Is there a way to separate out the source of the noise (fan vs compressor)? If it was the compressor, is there anyhting I could do about it? If it was the fan, is there anyway to improve the balancing that a home owner could do?

Take Care all
Ian

A fan out of balance usually causes a noticeable vibration.
A low pitched resonant rumble is the compressor.

I would think this noise would fall into the resonant rumble category. I am guessing that there is probably very little I can do to improve things?

Correct. Not much you can do with compressor noise.
Many times that noise is transferred into the building thru the refrigerant lines.

I can feel my compressor running. I can tell by the sound how it's working.

It is funny. I am on the second floor above the condenser and the refrigerant lines are directly beneath my feet when I am sitting at my desk that I rarely sat at pre-covid. If it were being transferred via the refrigerant lines, Is there a way to damp it out.

Hi, are the pipes exposed in the ceiling under your feet?
