We've had similar problems here. The kitchen was always too cold or too warm so installed an in-line duct fan. Helped some. Main problem was the ductwork would shift slightly and the fan blades would chatter against the sides. Semi-solved that problem rigging up an adjustable suspension. The real fix was when we had the addition built and they replaced that section of ductwork with a larger-capacity duct.
Up here in the Computer Room (upstairs of the original 1-story house) it gets a little cool in winter sometimes. A duct fan mounted magnetically to the vent helps. One problem is the unit slid down; a piece of board and self-adhesive feet fixed that. (The vent is just off the floor.)
(Not sure if the problem up here would have been corrected with a bit of ductwork. They mis-identified the duct going to the bathroom as the one going to the Computer Room. They thought the problem was a partially closed damper -- plenty of air flow to the bathroom!! Most of the duct to the CR is between the walls separating the bathroom and the Sitting Room.)
We had a duct run to the Living Room separated some years back. I was doing so work in the storage area where the furnace is and happened to look and didn't think things looked quite right: the alignment of the two sections was off by about two inches. There was air blowing out of the duct but it was weak -- always thought it was because it was at the end of the house (end of a long run).
