You need one of those hand held smoke generators, often used in buildings
to check for air leakage (check the links below). In this case you would
be looking for air leaking INTO the ductwork or component parts at the
seams. You squirt the material in the direction of the seam and watch to
see if it is sucked in or simply disperses (i.e. no leak, in that case).
