A duct leakage test is performed on a ducted heat pump system using a duct tester (blower fan) and a digital manometer.
Image
A flow grid is inserted into the filter grille/slot to directly measure airflow.
Image
A nitrogen pressure test was completed on this ductless mini-split heat pump using a digital manifold gauge.
Image
A static pressure measurement is taken on this air handler using probes on the supply and return sides of the fan.
Image
A vacuum decay test is performed on this ductless mini-split heat pump using a digital micron gauge for accurate measurement; a deep vacuum is achieved quickly by using large diameter, vacuum-rated hoses, and removing valve cores
Image
An IR camera image shows gaps around HVAC flue pipes allow conditioned air to leak through blown fiberglass into the attic
Image
Infrared thermography during depressurization testing reveals air leakage at corner of spray foam-insulated room where wood-to-wood seams in framing were not air sealed
Image
Limited attic access can make inspections for missing air barriers and insulation challenging
