Is it good feng shui that the air outlet of the central air conditioner faces the main room of the main room?

It’s not very good, it smells like “disrespecting the Lord”. Affect family harmony.

It is recommended to change the air outlet position of the air conditioner appropriately. If it is an air outlet for ceiling decoration, you can stagger the position and open another air outlet. The original air outlet should be blocked with a gypsum board of suitable size and used as an inspection opening.
