"Open Interior Door System"

Any suggestions for adapting to a new home constructed utilizing the above system? We were all (neighbors) advised we need to keep our interior doors open including bedroom doors in order for all our rooms to heat/cool. There is a "central" return but that return is in the back of the home.

There are a number of reasons we would like to actually use our bedroom doors, particularly at night. We were given a requested Manual J calculated off a floor plan and note the temperature design specs are still not being achieved.

Texas (north hell) locale, 3 ton, 2500 sq ft.

Any suggestions?


Thanks
