Round Louvered vents in ceiling

Camping mates, I have several round, white louvered vents in the ceiling of my 2005, Georgetown 375. I have almost nothing coming out of them when I have the A/C on, most if not all of the cold air is escaping from the vents on the A/C units themselves.
When I have the heat on, likewise there isn't anything coming out of the vents either. Since this past weekend was the first time I needed to use the A/C, I haven't had any exptectations of what would come from the vents. (and yes, I did open them!!!)

Thought you smart RVrs could help me out.

Ron

Are the Air Handler "dumps" open? In most floor plans you have to choose between the "fast cool down" from the "dumps" or a more distributed air flow from the vents.

If your dumps are closed and you still have poor air flow, you will need to check the ducts for a blockage.

Where would you find that option

Would this be inside the A/C unit itself? Not really sure I have ever dealt with this sore of thing before.
Thanks for your reply though
Ron

Not sure if I have a photo of the air handler with the cover ON!

But there are slide doors on the air handler (the place where the filter is located on the ceiling). Those doors are "dumps" for rapid cooling of the living area. They divert all air flow from the entire camper to the area directly below the air conditioner.

On my it's a set of louvers on the inside cover of the AC unit itself. Right next to the filter. There's a little slider. If you push the slider one way lots of air comes out right there. Push the slider the other way and it blocks the air dump. Forcing the air to go to the vents.

I only have one AC unit. When it's running and the air dump is closed you can tell air is coming out of the round vents but not a lot comes out. Still it cools things off pretty well.

As stated, you have to have the vent on the ac unit itself closed to develop enough pressure to divert air down the vents in the ceiling. Its an alternate path for airflow that allows quick localized cooling. To really feel it out the ceiling vents you need both ACs going since the outlet surface area is so large and they are connected.

I didn't think the airco acted as a heat pump, (like the ones we have at home), we use the furnace for heat or am I missing something?

I believe the heat just comes from your furnace throught your floor vents.

I also have the ducted AC on our new 21SS. You simply close the 3 vents on the AC unit and the air gets directed out to the other vents. Works great and much quieter in that mode. You can also spin the smaller vents to direct the cold air where its needed more..
