What effect can mold growth in an HVAC system have on occupants?

Will make all occupants ill
Is acceptable if limited to the return ductwork
Is acceptable if limited to the air handler
Can make some occupants ill

The correct answer is: Can make some occupants ill

Mold growth in an HVAC system can significantly impact the health of occupants, particularly those with existing respiratory conditions, weakened immune systems, or sensitivities to allergens. The correct answer reflects that while not all occupants may be affected, a portion of them can experience health issues as a result of mold exposure. Symptoms may include respiratory problems, allergic reactions, and other health-related issues. The other options present misleading or overly broad assessments of mold's impact. Saying it will make all occupants ill inaccurately implies that everyone is universally affected by mold, which is not the case as individual responses to mold can vary significantly. Suggesting that mold is acceptable if limited to either the return ductwork or the air handler underestimates the potential for mold spores to be circulated throughout the air system, thereby affecting the indoor air quality and potentially harming occupants' health even when the visible mold is confined to specific components of the HVAC system.
