return vent


is there sufficient heat coming from the register? i don't think a return air duct will make that much difference.
how well is that area insulated? windows all caulked and sealed?

return vent


Two returns added to my father-in-laws main living area made a night and day difference from what he tells me. You certainly do need that air flow from what I've experienced.

I've read that you should never have a return on an exterior wall. In any of the homes I've owned, the cold air return was panned in a floor joists back to the return of the furnace. All depends on your setup though. (i.e. - 1st floor, 2nd floor, basement, crawlspace, ect.)

return vent


You can use a transfer grill if running a return to the room can't be accomplished thru a basement or crawl space.

Do the other rooms have a return each, or is there one central return for the the whole home.


Older home used out side wall return placed under windows. Of course the older furnace threw air in excess of 160*F in huge slow moving volumes thru larger then today's ducts and blanketed the rooms more thoroughly. The idea was the cold air return would cause "waterfall" down the window of heated air.

return vent


Is the door to this room under cut.

Did the home originally have hardwood floors, and then get carpet, that covers the under cut.

Does the room get more air with the door open then closed. If not, a return won't help.

Returns are not panned to the supply. If it was, it would then be a supply.

Returns are panned back to the return duct, or drop.
