I bought this recently when it appeared that the 13 year-old Frigidaire version in my mother's garage  was having problems this summer during a heat wave.   However, after I checked things over, the old unit is still working just fine, so I am holding off on replacing the old one, We will keep this New A/C unit in storage for future use.  I got it at a good price, and it's a Keeper, so I'm glad to have it ready in the future.
