it is possible but.. it should be relocated in another area

return air's are an important vent in your HVAC system

it is not a good idea just to remove them completely

you want as much air going back to your furnaces as possible

Do not cover up your cold air return. If you can relocate it to another wall that would be good and if not leave it right where it was just put it in the floor with a floor Grill. Without your cold air return your heat distribution will be messed up and result and bad air and bad function to your furnace. Do not eliminate it. Hope this helps you

Removing returns or rerouting them can radically change the heating/cooling dynamics of your home.

Totally getting rid of them is very dangerous, as a room, especially the further away from the furnace, needs a return to allow for air to be able to sent to the room. Without a return he furnace has to force air into a space. Air will travel he path of least resistance, so eliminating the return may mean nothing on your 2nd floor will get heat or A/C.

In some cases, rerouting can have a similar affect. Again, path of least resistance as well as volume and distance can all change thus. Your HVAC system was engineered so that the volume of returns and supply vents are correct for each room to heat/cool relatively evenly.

I would consult with a professional before attempting this on your own.

Yes as long as you establish another teturn from the area. You cannot blow air into a bottle. The room without a return will be cold in the winter and hot in the summer. Rule of thumb you return .66 percent of the supply air to a room. An example ,800 cfm supply, you exhaust or return approximately 500 cfm. Think like air how would I get out of this room? I have never seen a house that could not be succesfully altered to provide a return just use some imagination. All the best Jack
