Question

What's the difference between in the window versus in the wall air conditioners?

Answer 1

Hmmm, no offense meant, but essentially no difference at all other than placement, and most often either can be interchanged. The Unit placement in some measure, depends on a desired location, and a size needed that may not fit a convenient window. OR in a situation where the homeowner may actually want to use the window for it's inteded purpose.

   Certainly a wall mounted, means cutting, disrupting the structure, creating the framework within the cut out to return to supporting what is adjacent to the unit.

   The venting remains the same. The issue is, in my opinion, as I suggest.

   12,000 BTU equtes to approx. a 1 Ton AC unit. In a standard formula, depending on who you talk to, 1 ton is considered adequate for 500 sq. ft to be cooled. I have seen that number as high as 750 sq. ft. SOOOOOOoooo, that said, if the AC unit, wall or window is thought of, to cool an entire house, and the house is 1200 sq. ft. (modest size) you could probably assume an AC unit should be 36,000 BTU, to do an adequate job. The issue in that notion of course, is that the source of the cooling is only coming from one place, and variations in temps can be evident, the farther away one is from the unit.

   Obviously in any house, multiple units can be used, and doors closed, etc. to focus any cooling more narrowly or directly.

Just my two "sense"

Answer 2

Wall mounted units tend to be larger units, with more cooling capacity.  They are also built so that they extend farther from front to back, than a window unit, to make up for going thru the wall.  Because a wall unit is larger, it tends to cost more than smaller window units, but really, its about the same as a similarly sized window unit.

Some wall units also come with a 'heat' option.

If you are thinking of putting a window unit in a wall.... you'd have a problem with the draining of the unit.... it would tend to keep your wall wet., So that's not a good idea.

If you are thinking of putting a wall unit in a window.... you could do this, if you build in some kind of support to hold the unit up... it'll be too heavy to just rely on the window to hold it.  So you'd need to build a platform, and bracing to support it.

Answer 3

1.  Cost (Window usually cheaper)

2.  Ease of installation (Window easier than wall)

3.  Power consumption (Wall usually less for same cooling rating than window)

4.  Amount of cooling space (Wall units usually bigger)

5.  Size of the unit (Window smaller)

That's pretty much it in a nutshell.
