Answer: In this method all the registers are sealed with tapes and the duct is pressurized. Then a fog machine is introduced in the ducts, aiming the the fog nozzle at the fan blades, without letting the fog get drawn into the vent holes in the motor. You have to watch for where the fog pours out. The site where it pours out is a site of leakage.
