I have a very efficient window-mounted air conditioner used for only two months.
I have to move out so I am selling it for a low price. The conditioner is in a very good condition since it was not used a lot.
Here is the link for the air-conditioner on Amazon with its specs:

Please send me a message if you are interested.

Thank you.
