Our 1948-vintage home was retrofitted with central heat & air decades ago, using the uninsulated exterior wall cavities for return air. Likely a code violation even when done, I don't know. Of course, at a later point, someone blew in insulation into the walls. Two great things do not always make a peanut butter cup.

We bought it in '98, and the HVAC kicking on would SLAM the basement door closed, as the stairway had become the primary return air, presumably using leaks and vents in the basement to get that air into the flow. Geesh.

We have done extensive renovation and added enough returns that there is little draw down the stairs now.

I do have a heated basement, but will evaluate the need for taping in the basement and attic this spring.

Great site, Daox. Cannot believe I just found it from a Jough96Accord post on cleanmpg.
