Yet my 20 year old Fedders air conditioner should have pin up.

No A/C plugs are made to assume the unit is mounted higher than the

Yet every window in the house is higher than every recepacle in the house.

The cord goes up too, in the direction away from the ground pin.
On a washer, the cord goes down in the direction of the ground pin
.... assuming you install the receptacle ground pin down.
