a 20 yr old house has a very good chance of having venting and or duct-work that has fallen, collapsed and had dampers accidentally closed while finishing a ceiling or basement...I see this all of the time.
Vent filters.....on either the hot or cold restrict airflow. Just because the store sells them doesn't make it a good idea ...EVER.
Regular fiberglass media filters (see through) cheap filters changed monthly
are the best way to go. Not doing it monthly will cost $$$$$$
There's allot more but I dont want to Cliff Claven the hell out of everybody.

Thanks for the reply. I am afraid to ask, but if the duct work has fallen or collapsed, what is the solution? Anything that might not require the basement ceiling to be opened up, or upstairs flooring removed? How much to get it checked out to make sure there are no breakages in the ductwork?
Would the dampers all be located pretty close to the furnace? I tried closing off the one to the room that was getting to the highest flow, but it didn't seem to improve the flow coming out the other vents.
