Which manufacturer makes the best air conditioner?

 The best according to the experience of the Japanese industry then the US and then the Korean

I cannot realy say which manufacturer is the best because here in South Africa we use Dunham Bush, Carrier, LG, Samsung and a lot of other types and to me it depends on how you maintain your unit how long it will give you proper service.

I think Trane , Carrier & York
