Thanks
On the NGs, when the APU is running on the ground, both packs can be operated in the HIGH position to cool (or warm as the case may be) the cabin. It is essential in during the summer, esp. in IAH.
As far as the "ER" designation goes for the -900, I think there is a misconception out there. It has nothing to do with range. Per the company the terms used interchangeably are:
Extra Rows (some of us commuters like to call them Employee Rows)
or
Enhanced Revenue (as was mentioned above).
