re: Adding another return air vent

I have an air return in every room of our house. AC company says ours is the most “unique” set-up that they service...I don’t think he means that in an enduring way

So that's the way a lot of the homes here in PA are set up. I have a small return in every room except the bathrooms. One main filter before the return duct goes into the furnance/AC coil. I never saw it until we moved up here a few months ago but man its a lot better than the one huge return grate I've always had down south.
