Air conditioners I cannot find on the Internet anywhere, not even at
General Electric's web site.

GE 8000 BTU AGW08FD
GE 8000 BTU ASW08FC (apparently newer)

GE 6000 BTU AGW06LC

I cannot even find "AGW" or "ASW".

Also helpful would be an explanation for their part number coding.
That way, at least I could tell something about the units and how
they might compare to similar units. Apparently the number represents
BTU rating.

Thank-you.
