A *lot* of noise!

The ducts in our DWMH are a fairly thin metal, so we're used to them making some noise as they expand and contract.

However....

In the past few days, one of our living room ducts makes a LOUD BOOM each time it expands or contracts.

What can we do about this? Has something come loose? Or would it be a good idea to wrap insulation or something around that section of the duct, to absorb the sound a bit?

Any help appreciated!

Hi,

You'll have to use a light laid down in duct at one register and hold a mirror down in duct at next register and look toward light to inspect.


It may have come loose. Wrapping with insulation would not help much if any, best to find problem and repair.

May need a pop rivet, foil tape, etc. to repair if damaged.


May need to open belly underneath at area and look from below.


Thanks,

Thanks for this answer and the others, Robert! Sorry for the delay in responding; I hurt my neck and haven't been online as much lately....

Hi,

You're very welcome, happy to help. A neck injury retired me from

Law Enforcement, so know all too well about that. Sorry for your

injury, take it slow and be careful.


Thanks,
Robert
