Company, written in October 2007. It covers a.c. EER values 25 years ago
and 15 years ago.</DIV>

<DIV>I'm working on an energy audit for a building with old window A/C
units. The average age is about 15 years old. Does anybody know where I
can find a good estimate for the efficiency of a 15 year old unit?</DIV>
<DIV> </DIV>
<DIV>I know there is a wide range of efficiencies, then and now, depending on
how much you are willing to pay. I'm looking something I can reference and file
in my report to show where I got my numbers.</DIV>
