Our current 220 volt 23,000 BTU/HR home air conditioner has an EER of 8.5,
and I would like to know what the energy savings would be if we replaced it
with a unit of the same BTU/HR but with a 9.6 EER. The current A/C makes our
power meter literally spin like a top every time the compressor kicks in. Do
you have to double the EER in order to halve the power consumption?

My exact calculations are at the office, but suffice it to say it is an
exponential relationship. Moving to 9.6 seer will not be worth the money. I
would replace the unit (and indoor coil, if it has one) with at least 12
seer.That has become the standard for new construction, and you will realize a
payback over about 5 years.

Yes.

And the exponent is one.

Are you really in the heating and cooling business? :-)

what are your general impressions of geothermal cooling systems, thermal experts?
