My house was just under 1700 sq ft and I converted the 20X20 carport into a new living room with maybe 75 sq feet of that space a stairwell to my upstairs addition (over the new garage I built).....so it was 325 sq ft of usable space.
My HVAC contractor put 3, 6" round vents in the room that are R8 wrapped ducts. When the AC or Heat comes on, I can feel air, but because of the long run from the air handler and many other vents on the line, the air pressure is a little low. The return is through an eat-in kitchen and hallway probably 40 feet away....it just doesn't have enough pressure/draw to compete with the closer rooms to the air handler. I've gone to all the vents in the house and tried closing them a little to help raise the pressure, but it doesn't appear to help much.
I've thought about putting an in-line fan in one or more of the ducts in the ceiling, but don't know how well that would work. I also am concerned that it will be on all the time or be noisy.
I thought about cutting a hole in the floor under my stairs and running a 50+ foot return duct to the air handler somehow in the crawlspace to help pull more air with negative pressure. Does anyone have any suggestions?
