Where is the drain located that's not seen dripping? It may not be the only drain route. Can't say what's the design standard in AZ but here in TX the primary drain is typically routed into the household plumbing so the discharge isn't seen. A secondary drain is routed to an exterior location so any dripping there is a visible signal to the homeowner that the primary drain is clogged.

there is two drains, they both exit the attic on the side of the house, so if there were condensate i could see them physically dripping. one drain is for the drain pan, the other is directly from the air handler and both are patent.

There may simply may not be enough moisture in the air to condense. What is the humidity level?

6% humidity. so maybe thats it?

Yep, I would say that is the issue, which is not an issue.
