Ceiling Assemblies
The ceiling assembly is the half of the system inside the RV: it mounts to the underside of the roof opening, carries the controls and sends air into the room or the ducts. Non-ducted assemblies blow directly into the room and carry the controls on the unit. Ducted assemblies feed the ceiling ducts and pair with a wall thermostat. Not sure which you have?
