2014 BC3650 AC System/Whisper Quiet?

I've been reading the HUG regarding AC operation. How do you know if this unit has the whisper quiet system? Front BR has the high profile unit on the roof with AC ducts in the ceiling. LR unit is also high profile with several AC ducts in the ceiling. Are the ducts hooked together? I'm wondering if Heartland is putting in the shared duct system for AC units without calling it whisper quiet.

After posting this topic I saw a similar post. Sorry about that. Any new insight?

Hi lynndiwagoner,

I think the Whisper Quiet design is in the Landmark only. While similar, the Big Country may use different A/C units.

We have a 2014 BC 3650. The AC units are not the whisper quiet. I'm not sure about the shared ducting.

Thanks folks.
