The city gap was about $62

The $62 city gap was much smaller than the $384 difference between the mini-split and small-window averages.
Portable and larger window units sat in the middle
The small-window category averaged $181.10 across 12 cities. Even the highest city, South Philadelphia at $184.75, sat far below the next two categories in the table.
Portable AC units from 8,000 to 11,999 BTU averaged $221.24, while window AC units from 8,000 to 14,999 BTU averaged $325.49.
Unit class created a much larger price step than the city range within each class.

Mini-splits averaged $565.54, about $384 above the small-window average. They also had the widest city range among the AC types: $541.23 in Westside Jacksonville to $597.62 in East St. Louis.
Portable AC units at 12,000+ BTU averaged $374.18, and through-wall units averaged $532.50. Unit type changed the scale of the price comparison far more than city did.
