Paul,

Thank you. I've learned so much via this message board I'm not even embarrassed to ask "dumb" questions anymore.

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.

Thanks Paul. The Panasonic link was especially useful.

The EER or Seer rating is an effiency rating. The reason most are ten, that's the lowest the government will let you manufacture.

The compressor has an amp rating on it's plate.
