2nd AC prep means they have run the 120 wire to the roof vent where you install the 2nd AC. Depending on the OEM, they may also have run a Wall Tstat wire from a wall location to the roof Vent also. THAT will have to be determined by a call to the OEM. But, it is an easy thing to do to check. You drop the inside vent plenum(4 screws) and you will usually see the 120 romex wire. IF they ran the tstat wire, you will see it also. MOST OEM's do NOT connect the 120 romex at the 120 Breaker center, but some do. That is something the installer does when adding the AC. Doug
