First was the sleeve, which weighed just a couple of pounds. This was easy to fasten into place - particularly helpful if placing the unit at the top of the window.
Once this was properly fastened, then I'd simply pick up the main part of the unit and slide it in.
Anyway.. while I can still find similar arrangements for through-the-wall air conditioners, I haven't located any that are built for windows.
- The window design is a bit more efficient energy wise as the outdoor "cooling air" that flows over the compressor comes in through the sides of the unit and out the back.
The "through-the-wall" ones use just the back grill for both the incoming and outgoing air (there's a baffle in between) so it doesn't flow as easily and costs a performance penalty.
Thanks muchly for any pointers
