Frank,
I've done a few web searches. Try this page at
City Water Light & Power of Springfield, IL for some background on the EER.
I also found this link to a range of
Panasonic A/C units. The data on each model gives the EER and the actual current consumption, which is enough to do an approximate power factor calculation.
I took a sample of units from 5250 to 20,000 BTU and they all calculate out to a p.f. of about 0.9 to 0.95 -- Pretty good! The lowest I worked out was on the 6000 BTU unit at a p.f. of 0.89.
I don't know if these are typical of your A/C units in general though.
