         6 . The wall unit in  claim 4 , wherein the back comprises an outwardly directed perimeter flange, which in use, extends adjacent to the exterior surface of the exterior wall and conceals any edges of the through opening therein. 
     
     
         7 . The wall unit in  claim 1 , wherein the system is a split-system comprising an outdoor unit which is operatively associated with the wall unit. 
     
     
         8 . The wall unit in  claim 1 , wherein the system is an evaporative air cooler system. 
     
     
         9 . A split system air conditioner comprising a wall unit adapted for installation in a through opening provided in an exterior wall of a building which has been vacated by a wall air conditioner unit, wherein internals for the wall unit are substantially housed within the wall's through opening and between interior and exterior surfaces of the wall. 
     
     
         10 . The split system air conditioner of  claim 9 , wherein this further comprises a mounting for the wall unit, said mounting being adapted both for insertion in the through opening, and for supporting the wall unit. 
     
     
         11 . The split system air conditioner of  claim 10 , wherein, the mounting comprises a through opening for nesting the wall unit. 
     
     
         12 . (canceled) 
     
     
         13 . An evaporative air cooler comprising a wall unit adapted for installation in a through opening provided in an exterior wall of a building which has been vacated by a wall air conditioner unit, wherein internals for the wall unit are substantially housed within the wall's through opening and between interior and exterior surfaces of the wall. 
     
     
         14 . The evaporative air cooler of  claim 13 , wherein this further comprises a mounting for the wall unit, said mounting being adapted both for insertion in the through opening, and for supporting the wall unit. 
     
     
         15 . The evaporative air cooler of  claim 14 , wherein, the mounting comprises a through opening for nesting the wall unit. 
     
     
         16 . (canceled) 
     
     
         17 . The wall unit in  claim 2 , wherein the wall unit comprises a removable back, which in use, is substantially flush with an exterior surface of the exterior wall. 
     
     
         18 . The wall unit in  claim 3 , wherein the wall unit comprises a removable back, which in use, is substantially flush with an exterior surface of the exterior wall. 
     
     
         19 . The wall unit in  claim 5 , wherein the back comprises an outwardly directed perimeter flange, which in use, extends adjacent to the exterior surface of the exterior wall and conceals any edges of the through opening therein. 
     
     
         20 . The wall unit in  claim 18 , wherein the system is a split-system comprising an outdoor unit which is operatively associated with the wall unit. 
     
     
         21 . The wall unit in  claim 19 , wherein the system is a split-system comprising an outdoor unit which is operatively associated with the wall unit. 
     
     
         22 . The wall unit in  claim 7 , wherein the system is an evaporative air cooler system.
