Currently expanding duct work to accommodate heat pump cfm
requirements. Need 2000 CFM and have the duct sized out just not sure
where the return vents go. House is open concept (2000 sq/ft), each
bed room has high wall mounted return vents that are buried and can't
be enlarged, therefore hoping to add more return vents on main floor.
Main return duct will be upgrade to accommodate total retrun air flow.

The plan is to increase the number of stud opening from 2 to 5 for an
additional 600 cfm (1 stud opening 3.5"x14.5"=200cfm). My question
should I just cut out floor vents or hack through the wall down
through the floor to make wall returns? The floor vents would probably
be easier; however I'll go the extra mile for wall vents...... less
change to lose my keys.

Why did return vents move from the floor to the walls anyways?

Any advice is much appreciated.

You're going about it all wrong, you need to blast a hole in the wall
and run a 50 inch diameter duct through another hole you will cut
through the roof. When you have that done you then must replace the
thermostat with a digital one.

Thanks, but not sure what you mean. My heat loss calculation showed
that other rooms only require slightly more heat/cooling but not
enought to start blasting.

Just wanted to know the advantages of return vents on the walls vers
on the floors.
