I believe
that the EER is how many btu's of cooling an A/C can provide for each KW of electricity used. The math should be pretty simple to figure out your savings.

Pretty much....
EER is BTU/hr output divided by Watts input. Not kW. That would have been pretty obvious when you went to do the math, but I thought I'd mention it.
Anyway, EER1/EER2 = Watts2/Watts1, assuming the BTUH output is the same.
Now all you need to do is figure out how many BTU's you go through in a given year, convert it to kWh, convert that to dollars and you've got it.
Provided you say it really quickly like that, it sounds easy.0 
jim based on what you're saying. the savings would be 20%
10.9 eer/13.6 = .80. is it that straight forward?
thanks, jay0
