    coil area required for higher efficiency for one thing.

    Becuse if it was as small as you neighbours, you'd think you paid too much for it. J/K

    As above, coil size needed for efficiency.

    It is a manufacturing thing. This way different brand units will not all look rectangular or square or round. Depending on SEER rating they may have smaller coil surface compared to a larger one.

    Yes, higher SEER units usually physically larger.

    Most A-S/Trane units are very large, I think the Spine Fin coil has to do with that. The old clunker recip is big which doesn't help sizing or weight.

    But efficiency does have a lot to do with it. A 16 SEER Ruud is good sized too!
