window air condtion vs central air condition

Window air condition  ~$100

Central air     ~$3000-$4000

Why can't we buy a couple of window air condtions for renters when the central air goes bad?

I think the US air condition industry is the next car industry. Their product is too expensive, too complicated. The window air condition or the portable air condition is "good enough"

• 但是十個這樣的window unit也比不上一個普通的中央冷暖器係統有力。 -梁山sl- ♂ (0 bytes) () 05/30/2012 postreply 20:02:33
