Sorry, for question #1 I meant to ask:
1. How can the packaged unit have a higher cooling capacity and CFM using 1.4A (322 watts) less power, but yet have a lower SEER and EER rating?
I am trying to decipher the efficiency of a ducted split system versus a packaged (central) system. For the sake of this discussion, assume both systems have the exact same amount of ducting, and thus this is strictly about unit efficiency. Take for example, the two following configurations...

The city I am in, and most neighboring cities allow underground non-living space to touch the property line (such as my underground garage). Underground living space must follow the same setbacks as above ground.
