Haier, Hisense and Midea are extremely good brands for air conditioners and they are big in PRC which isn't exactly an easy market to survive in unless you are extremely good.

Hisense air conditioners can be found as standard fit by developers these days, most recent one I know off is Boulevard 28 by Beverly Group, every unit equipped with this brand.

Many Hitachi air conditioners do utilize components from Hisense as well.

When it comes to brand name air conditioners, it is only worth while buying Japanese ones if you are planning on buying a high end or premium model else you are basically paying for the name and nothing more.
