Agreed that Friedrich is a very good brand - but don't be stuck to it if it's only for the slieve in the wall - tons of other models will fit the slieve. If you can get a better deal on a quieter unit (Friedrich is very noisy, IMO), which is energy-star compliant, go for it.
I read their site, it said very quiet.. Here's the link..

Also, can anyone tell me what's the difference between the inwall Ac and the one wall sleeve replacement. Since there's already an inwall ac there, do I get the inwall ac or wall sleeve replacement..
Thanks
Do you mean in wall as you have a hole in the wall for the AC to go through. Or are you looking for and AC that mounts on the wall like this one http://www.kingersons.com/mini-split-air-conditioner.html#24000minisplitairconditioner
I prefer the portable ones that you could roll to any room i think they have a sale a costco. I have a costco card if you need to get in.
So I guess the question is, the in-wall units that you are planning to replace - are they 'just in the wall' or do they have a branded slieve?
If you don't have a slieve, than just get whatever fits the old hole best and go with Consumer Report recs. Oh, and don't forget 'liquid nails' - fantastic product for filling in all crooks and crannies.
(On a tangent - if they color it with gray or black, some pet stores sell it as 'waterfall foam'. Same stuff!)
