Hi All,
I just got AC installed, when it kicks on the return air duct which is 24" x 24" starts whistling. I took the metal grate off to see if that was the issue and it was not.
I also tried moving my hand around the opening to see if I could affect the sound but nothing changed.
How can I track down and muzzle the whistle? Thanks!
