Home central air conditioning is installed concealed in the ceiling to integrate with home decor. It is designed for family use and has centralized control. Packaged air conditioners are split units commonly used in homes and small offices. They have advantages in power and wind but cost more. Home central air conditioning and packaged air conditioners have similar cooling effects but central air circulates air through larger loops in the ceiling while packaged units have shorter circulation in a smaller space. Central air conditioning uses less space than packaged units.
