Duct BlasterÂ®. 1  A Duct Blaster is used to directly pressure test the duct system for air leaks, much the same way a plumber pressure tests water pipes for leaks. 2  The Duct Blaster fan is first connected to the duct system at the air handler cabinet, or a return grille. After temporarily sealing all remaining registers and grills, the Duct Blaster fan is turned on to force air through all.
In my inspections I use a basic 3-LED tester with a gfci test button and a 3-prong grounding plug to test outlets. The readings are: 1)ok; 2)hot/neutral reverse; and 3) open ground. Recently on an inspection I found 6 duplex outlets that were protected by one GFCI outlet.
