What are the advantages and disadvantages of domestic vs. imported central air conditioners?

The question is not clear.

First of all, now the real meaning of the "original imported" air conditioning has been a few extinct; can be associated with foreign countries are some foreign brands in the domestic assembly of air conditioning production.

Secondly, air conditioning, refrigerators, color TV and other industries are after full competition in the market, the current domestic big brands of air conditioning products will only be better than foreign brands, and never worse.

Moreover, now if you still revere foreign brands, that foreign brands of things must be better than the domestic that is really stupid. Foreign capital, especially Japanese brands of such products, poor quality, low level of technology, not to mention the price is high, and after-sales service is very poor.
