Should HVAC be in ceiling or floor?

The best placement for HVAC systems depends on the type of system, the size of the space, and the desired air flow. Generally, ceiling-mounted systems are best for larger spaces, as they can provide more even air distribution. Floor-mounted systems are better for smaller spaces, as they can be more easily adjusted to provide targeted air flow. Ultimately, the best placement for HVAC systems should be determined by a professional HVAC technician, who can assess the space and determine the most efficient and effective placement for the system.
