In these parts (GA), most 2 story homes have separate systems for first floor and second floor. The a/c for the first floor is in the basement and the a/c for the second floor is in the attic. Basement seems better since it's cooler.
Why wouldn't they put both the first and second floor units in the basement - seems like it's easier on the system (and easier on the service tech)? One ofmy firends told me it might have to do with running ducts from the basement to the second floor but I didn't understand.
