does this mean wherever the disconnect is mounted there must be open space 18" up and down (of center) and 15" left and right? what about a minimum height from ground-would that be 18"?

The disconnect must be placed in a readily accessible location and within sight of the equipment it is supplying. NEC 440.14

Readily accessible mostly means not higher than 6' 7" off the ground, and not behind the condensing unit where servicing the disconnect would be a PITA.

The "whip" from the disconnect to the C/U must be identified for the use and the C/U must be properly bonded using an equipment grounding conductor.
