We have a 1080 sq. ft., 1-floor (no basement) house. Our furnace and cold air/AC returns/registers are literally almost in the living room/main sitting area and it's very loud year round, making for a not-very-pleasant time whenever my wife and I are trying to relax and watch TV, or do anything else in the main room of the house.
Besides spending thousands of dollars (that we don't have) moving the furnace to the attic or away from the room, is there ANY way to reduce the noise that the registers/returns make whenever we run out hot/cold air system? I've looked elsewhere without finding any good solutions.
