Humming freon line.
 
I have a new 4 ton heat pump system with an annoying hum.
The A coil, outside unit and froen line have all been replaced.
None has helped.
Is this something you have to live with?
Are any brands less prone to this than others?

Make sure that there is no cement around the pipe as it enters the room.
Use putty instaead
Hang your pipe on rubber bands, Make sure your unit has rubber isolaters under the condensor.
And make sure who ever charged the unit did not over charge it with too much freon.
