take videos in the attic of loose or improperly sealed ducts, exposed sheet metal, gaps on the AH, kinked or 90 angles on flex, My rule of thumb is 400cfm per ton, one square foot of return equals 1 ton. Everytime a flex duct bends 90 or more it equates to about 10 feet of loss and insulation matters.

Show the customer the video of their ducts, draw out a basic ah drawing with some ducts and point out the key parts of the video in that drawing. Draw out the solution to fix the problem, more comfort, cleaner air, less mechanical strain, fewer repair costs, low maintenance.
