I bought an Air Conditioner from Canadaian Tire & after one use found it didn't cool the room as the box said. (up to 300sq feet) so wanted to returned it.. Because I had used it, it was non-returnable - How do you know you like something unless you use it! Unbelievable...a note for others...If you buy it from CANADIAN TIRE AND USE IT...IT'S YOURS...Embarrassed they have the Canadian name associated with the store!
