Question Suspended ducts in attic


We are questioning the suspension of the ducts in our attic to increase the flow of air into our living/dining area. The air flow in our home is fine except for in the rooms which have the highest ceilings. When looking at the duct work in the attic, these areas have suspensed ducts which appear to be pinched for lack of a better term by the strap. What do we do to increase the air flow into these areas of our home? Would releasing the duct work from the straps hurt or help?

How many floors is your home?

There can be many options from improperly sealed ducts to inadequate return lines. As this is in cathedral areas your obviously dealing with a larger amount of heat capturing dead space. Depending on some more details (Direction these rooms face, floor, atic ventilation (type of), and number and position of supply and return ducts in these rooms) I would be able to be a bit more helpful.

Just to clarify, do you have ridgid insulated ductwork, or flexible, and where exactly are the runs "strapped"?

Check back soon.
