Convert AC from ducted to non-ducted
How big of a deal would it be to convert a typical Dometic 13.5k btu roof mounted RV air conditioner from ducted to non-ducted? Is it a do-it-yourself project for a typical RV owner? I have a newer ...

My big question is why?
I had ducted air in my 1985 class C, while I looked forward to the distributed and much quietier ducted air in my new 97 class C.
While it might be possible, it is not all that easy, as they do not make a interior grill that is non-ducted to install on a ducted A/C unit.
There is a company that makes a large vent that can be installed do it yourself on a ducted air conditioner interior grill, and it will blow a lot of air directly under the return air vent, quickly cooling the area within 3 feet of the A/C return air vent.
However that will blow directly down, and not distribute the air around the room.
It is likely that you will need to purchase a non-ducted air conditioner to replace yours to get the interior grill, and a rooftop unit designed to connect to that interior grill. Also most non-ducted air conditioners have the controls mounted to the interior grill, and just like a window air conditioner, they are 120 volt controls, not adaptable to a thermostat control. There are exceptions, where a remote control is used to control the built in thermostat of the non-ducted unit, but most are built in 120 volt controls.
Good luck,
Fred.
