A blower fan and monitor connected to a house furnace for a duct leakage test. All of the air vents in the house have been temporarily sealed. This system pressurizes the ductwork and measures the airflow through the fan and the resulting pressure within the ductwork. Duct air leaks are a major source of wasted heated or air conditioned air, resulting in waste and system inefficiency. This test can be performed on new or old construction to determine if the ducts need sealing or repair. Occasionally, this unit would be part of an extensive energy audit. This is a real world photo taken in a working environment, there is some dust visible on the monitor.
