We have a two-story with a full basement. Each floor is 24' X 32'. The duct noise from our heat pump has always been loud. Only the top floor has a return duct, about 18" X 18".

A technician said the adding return ducts on the other levels will reduce static air pressure and therefore reduce duct noise. Is that so?

Depends an awful lot on what type of noise,
and why it's generated.

How would you describe the noise ?

AS a vibration in the ducts ?

As a 'wind' noise from the handler ?

Have you noticed that the noise has become louder
in the past years ?

Have the ducts ever been 'cleaned' on the inside ?

Is there any insulation on (or in) the ducts ?

Lots of wind noise, especially in the kitchen floor vent, which is right above the main supply stack. It has always been like this. No insulation.
