Hi Jim,
You would use the existing air distribution face plate and thermostat that you already have. And yes, it runs through the same condensation lines. The only thing you are changing is the top unit.
I also discovered yesterday that I can run the AC with my lithium batteries. A couple of hours dropped it about 20%. So it’s not long-term but it was very helpful.
Sincerely,
Mary aka RoadLotus
