Air Conditioning - Sleeve / Through-the-wall A/C units

Good Day,

I live in a condo unit (12 year old building) with two sleeve openings in the wall for A/C units. One sleeve already has an A/C unit (original to the building and works well), but I am having a heck of a time trying to find an new A/C unit for the other sleeve.

The problem is that all the sleeve / through-the-wall A/C units that I see are 24" wide, but the sleeve in my unit is approx. 23", certainly less than 24". My questions:

1. Is anybody aware of a manufacturer that makes wall A/C units that are smaller in width ?

2. Will the installation of a window unit work if leave some space around the sides and top ?

If I can't find a wall A/C unit, then the only other option that seems feasible is a portable A/C unit that I can vent through the existing sleeve.

Any thoughts or suggestions ?

Thanks.

John

2. Will the installation of a window unit work if leave some space around the sides and top ?

No cause they cant get the intake air for the back side to the compressor. You cant block the sides where the air comes in it. Forget about the top


ED ;)

What is the brand of the original unit that's still there? Maybe check for models of that brand that might fit. I know Fedders made a lot of thru-wall units, which are still available.
As Ed said, don't try using a window unit, even with some space around the sides and top, it won't perform well.

Thank-you both for your replies. Fedders makes about 5 or 6 wall units...but they are too wide for my sleeve. At any rate, a few days ago I purchased a portable A/C unit. It should do the trick !
