Air Leaks: How to Track Down Air Bypass Leak or Air Leak Noises in buildings

AIR BYPASS LEAKS in buildings may in some instances produce not only drafts and high energy bills, but actual sound as air moves through building openings under windy conditions.

  • Air leaks at windows or doors, in high wind conditions, can produce a hissing or a howling sound.


  • BLOWER DOORS & AIR INFILTRATION - are used to measure air leaks, equivalent leakage area (ELA), and air changes per hour (ACH) in a building
  • Air leaks in ductwork often make a roaring or hissing sound.

  • STAIN DIAGNOSIS on BUILDING INTERIORS, how to diagnose stains on walls, floors, carpets, and how to determine the stain source - these articles can help track down air bypass leaks because moving air through soft materials (insulation, carpeting) or along surfaces (walls, ceilings) will often deposit dust or debris particles showing the locus of air leaks or movement.
  • Also see WIND NOISES at BUILDINGS where we point out that wind can move building components (rattles, squeaks, roars, hisses) or increase leaks through building openings (hisses)
