Arcadia A/C Duct

[HercFE]

I am new owner of a Arcadia 3660RL. I have only used it twice and have not had the opportunity to learn more because of A/C issues we had. Now that the dealer has repaired the issue, would someone explain how the A/C duct system works? If I close the slots on the roof A/C will it blow through the duct work? or does it only blow out the square roof unit?

Thanks and apologize for the dumb questions

Yes, closing the vents on the inside of the AC will force the air through the ducts. You have a larger 5er. Do you have 2 AC's? You should have the Racetrack system which flows AC air through the entire coach. Dual AC's for your rig should be a basic requirement...it would be if we owned it. In our experience 2 AC's blowing through the ducts feels like it triples the air flow over just one AC.

Yes we have 2. Great thank you and I am excited now.
