In air conditioning, moving more air doesn’t always help because cooling capacity is limited for the most part by compressor and heat exchangers capacity.

The right amount of air is needed to reduce humidity.


The problem here is that we’re missing NEEDED information to diagnose what’s really happening.

Why does a large motorhome have 2 A/Cs if they can only run one? That’s rare.

Even if you can squeeze 5 or 10 percent more out of a 13,500, is that enough? I doubt a vent will help much, but even if it could a little, it’s not enough to cool a large RV with ONE 13,500 or 15,000 A/C. Not in hot humid Florida summer.

In my opinion, the drop-in-a-bucket approach is unlikely to work in this case. We can guess one A/C is in bedroom and other in living room, and unless they are willing to completely segregate RV during day and night, it’s going to be tough to cool with one A/C at a time on a hot humid day. Nighttime should be easy, but 3 PM on a single unit not so much.


Just my 2 cents ....
