How can I reduce the noise from an air handler unit?

I have a Goodman AR42-1 air handler unit in an open closet. The setup looks like this:

When the air handler activates it sounds like this:

Current sound levels:

Everything off:           36 dB
A/C on and inside closet: 63 dB
A/C on with door closed:  59 dB
A/C on in Living Room:    55 dB

I don't have air handlers, but I am into audio.

Air going thru pipes is like a speaker. It makes noise. Make sure everything is tight. It may sound crazy, but I put a 2 inch plastic pipe to my ear and "pin point " where the noise is coming from.

Once all that is done, wrap the pipes. Improves efficiency as well.
