What Comes Through the Wall
Car exhaust (carbon monoxide, nitrogen dioxide), gasoline and solvent vapors, paint and chemical storage off-gassing, and lawn equipment fumes can all migrate from an attached garage into the home. The pathways include the door between the garage and the house (especially if it does not seal well), shared wall cavities, HVAC ductwork that passes through or draws air from the garage, and pressure differences that pull garage air into the home when the furnace or air handler runs.
A Source People Forget About
Many homeowners who address indoor air quality overlook the garage as a pollution source. If headaches, chemical smells, or exhaust odors are present near the garage-adjacent areas of the home, the garage connection is worth investigating. The assessment evaluates this alongside four other air quality areas.
