Signs of Black Mold in HVAC System

Musty Odor

A musty odor emanating from the vents is one of the first signs that black mold may be present in your HVAC system. This unpleasant smell, often described as earthy or damp, can indicate the presence of mold spores circulating through the air.

Black “Dust” Around Vents

Black “dust” or dark spots around the vents often comprise mold spores that have settled on surfaces and can be a visible indicator of mold contamination.

Persistent Nausea

Exposure to black mold can cause persistent nausea and gastrointestinal discomfort. If you or your family members experience ongoing feelings of queasiness or stomach upset while indoors, it could be a sign of black mold exposure through the HVAC system.
