To increase air flow between rooms should vent be installed on the upper or lower part of a door?
It depends. If your bedroom has a supply AND return duct, then no.

A room to room vent or duct would equalize this pressure and allow maximum CFM to be delivered from the central air/heat system.

How much to install central ac?
Adding central air conditioning to an existing forced-air heating system in a 2,000-square-foot house averages $3,500 -$4,000, and can be done by two technicians in 2-3 days, with little or no change to the existing ducting. If ducts must be added, the work time doubles, as does the cost to $7,000 -$8,000 or more. Estimates for an older, smaller house of 800-1,000 square feet with no existing duct work run $2,100 -$6,000, or as high as $10,000 or more, depending on the type and quality of equipment installed, the amount of space available for installing ducts and vents, and the local economy.
