Adding second AC to GD 3170BH

[Frozen001]

So at some point, I am going to add the second AC to our GD 3170BH. It is "pre-wired" whatever that means, but I assume it is just the electrical that is up in the ceiling cavity.

So anyone on here with a 3170BH that has done this... Does this unit have the ducted AC going to this area, or will the second unit just need a standard diverter. Also what about the thermostat?

At the end of the season, I will probably pull off the trim on the vent and take a look, but if I can start to prep sooner that would be great.

Thanks!

I just added the second on our Open Range. Like yours, it said pre-wired. That meant we had 12 volt,110, and thermostat wires at the existing vent. Ducts ran all the way to that vent, but had foil tape over them. Also had thermostat wire at the bedroom light switch. All in all, not a bad job. I’m sure your GD experience will be similar.
