Window AC efficiency ratings

What's a good rating for a window AC unit? Just about everything I've found seems to be running about 10, but I've mostly been hitting the big boxes.

Thanks
Steve

SEER 10 is your basic rating a good rating would be 12 or better

Not sure about the ratings, though I know this is an energy star unit. I have two of these 10,000 BTUmodels and they work great. Highly recommended...

BeGreen....think you have it backwards.....the "tougher" the number, the higher the number...the Fed numbers are lower (they're the minimum the manufacturers must meet) and the manufacturers respond with even better (tougher) higher numbers which indicates an even more efficient unit...........

I based my oppinion on central air. In the past year they ( energy codes) have increased the effeciency Seer from 10 to 13.5 How ever they extended the time for compliance another 6 months
to allow manufactures to sell off Existing inventory.

Since I don't own any Ac and never had, the window unit knowledge is limited. I suggested a Seer number that would be an upgrade, but did not know it was unattainable in window units.

Thanks for the info BB

Thanks all, particularly for the chart BeGreen. Ended up with a midrange 9.8 6500 BTU for $135.

As to Elk, does that mean there will be a bunch of deals on <13.5 SEER central air units? The mid-80's unit I have is about done, but I hate tossing somethign that still more or less works. On the other hand, I hate running it, because I know it's sucking watts like crazy. And the ductwork sucks, all being retrofit for heating, never really any thought to cooling. Hence the window unit for the bedroom. Terribly conflicted...

But I'm thinking I can make it pleasant enough for about $400 and 3 window slots.

I know the little LG we have is a 10.8 EER and the other sears model is 10.5 or 10.6.

You're better off ignoring the EER (to a point) and spending some money on mounting the unit properly and sealing up the area around the AC unit properly. That can make all the difference.

I am a big fan of the window-shakers.

Zero loss to ductwork.... and for the price of an annual maintenance contract for a 3 Ton central system, you can afford to replace the window unit every year.

The thing for me is humidy reduction. Set the thermostat at 74 and let'er run.

To coin a phrase--"zone-cooling".Hey, if we're comfortable all winter with our wood stoves providing "zone-heating", then why not just cool the area you spend the most time in?Save a buck: install an efficientwindowwall unit.

That's right where I'm at. I don't mind sweating during the day, I hear it's good for me. But I hate sleeping and sweating.
