A/C air flow

[Drussell]

I have a 2018 3720FK with the Peguin 15000 Dometic A/C in the living area and the Blizzard 15000 in the bedroom. The unit in the bedroom blows harder than the other one. All the intake filters are clean and the duct work is clear. Is this normal with everyone else? I was considering taking the unit off to see if there is any restrictions underneath but wanted to see if anyone else noticed a difference in flow
They’re both ducted together by the way

If one has better airflow than the other, check for
1. collapsed air return ducts.
2. Obstructed coil fins
3. At least one person has found the roof unit not centered properly over the ceiling cut outs

You can also check the air vents collar that goes up into the ceiling. Sometimes the collar is too long and protrudes too deep into the duct restricting airflow.
While you have it out check the tape around the perimeter.

Thnks for your response. I’ll do some checking. I don’t think the intakes are collapsing but went ahead and inserted pvc pipe into them with no noticeable improvement
