Somebody don't know their vendor sources
Maytag does not make air conditioners and never has.
If it say Maytag on it, it is either a Fedders or a Haier and possibly Heil now that WP is in the picture. Fedders made them one in 2002 that had a stainless steel cabinet..dang purty, but hard to look at in direct sunlight.
Whirlpool does not make air conditioners.
If it says Whirlpool, it is most likely made by Heil.
Both companies put their brand labels on the units, not many know who really makes them..
