How do portable AC units compare to their counterpart window units in
performance and efficiency?
Go to your local library. Get the issue of Consumer Reports that deals
with those appliances. Use Google for more information.

Here's a report from 2008:

That's interesting. They CR is reporting getting half the EER of
window units. Yet if you look at the specs of the portable units
the EER the manufacturers list is similar to the window units,
ie around 10 or better. I wonder what accounts for the
difference? Must be different testing methods, but you would
think the EER would be measured in some fair and standard
way.
