Noisy air return

We moved our HVAC unit from the basement to the attic and there's a lot of noise at 2 of the air return covers closest to the unit. What can be done to stop this?

Re: Noisy air return

Hi,
Sometimes lengthening the return flex will reduce the noise, or even a larger diameter flex, or both.
If the return flex is very short it will be noisy in some cases.
Is the unit in the attic suspended from the rafters or just laying on the attic floor?
Good luck!
