Interior overhead round A/C vents

[mr. seaview]

i have a 31 foot national seaview model 8310 with 2 rooftop a/c units.

i notice that when i turn on my front a/c unit and put my hand up in front
of my a/c vents that some of my vents are blowing out harder and others are
blowing less and a few are barely blowing? was wondering if this is normal
or do u think that maybe some vent ducts maybe blocked or plugged up
somehow? just wondering if anyone else has experienced this problem
and what did u do to rectify the situation? thanks for any comments ort
help??

They all blow different volumes of air

Not a problem. Some are just closer to the source. If you want to change the distribution shut down the vents a little that are closer to the source. The source being the A/C unit itself.
The air path from front to back is a cutout in the styrofoam ceiling insulation.

Had this problem when I first got my 8310. The PO did a good job cleaning up any signs of rodents however my vents were plugged with mice nesting. I spent a lot of time cleaning the rectangular vents by pulling a rag thru with a fish tape.

We have 2 roof units also. #1 blows hard in front and almost none in the bedroom. #2 blows the opposite. Run them together....and the circuit breaker activates.
