Like you said we love are Ace also and plan on keeping it a long time. I thought the same thing you should be able to hear the tv over the air conditioner. My tv is the same one you have in the same spot above kitchen counter on a bracket that swings out. I have not come up with an idea on mounting a sound bar at this time. I am not sure if sound bar should be mounted to the ceiling or under cabinet below the tv, or should it swing with the tv somehow.
