i'm just curious to know how often supply and return air ducts should be clean and what are the consequenses if you don't?

Come on. You can answer that question yourself. You clean them when they are dirty and the consequences are endless. Healthy dirtt lungs. Think about these things.
At least once a year, but there is no hard rule. If you have a dog in your house, there is dust all over.

In my house never, once a year is definetly overkill, unless you are the one with the machine for cleaning them. Then I am sure they would recommend once a month. LOL

Check in the IAQ section for more info, I think that's where it's been posted.
I personally believe cleaning ducts isn't exactly useless, but not exactly a regular maintenence type of thing either. Now, I'm all for sticking the hose of the vacuum down the register boots a few times a year to keep them clean. But beyond that the duct either
A: Shouldn't be getting dirty... use a filter and make sure the duct is sealed tight.
B: If there is dust in there it's so heavy it's already fell out of the airstream and is very likely not going anywhere.
When a duct cleaning is good is on a change out... increased airflow very well could dislodge that dust all over the house.
