Dont know if I got the right forum since its not a car part and its Free 
I have a real large a/c in my dining room window I use it to cool the complete downstairs of my house....
Its about 10 years old I cant find the tag on it that says what model or btu it is
It works perfectly and I can demonstrate it if you like
come get it it yours free in Mount Vernon
probably need two guys to lift it at least (not including me I dont lift)
want to get a smaller one for a different window so this ones gotta go
