Mold Resources

Mold in HVAC Systems

HVAC systems can support mold growth in coils, drain pans, and ductwork — and then distribute spores throughout the building.

Why HVAC Is Vulnerable

Cooling coils produce condensation. Drain pans can hold water. Ducts collect dust. Together these create conditions for microbial growth.

Warning Signs

Musty odors when the system runs, allergy symptoms that flare with the HVAC on, visible growth at vents, or recent water damage near the air handler.

Inspection Focus

We assess the air handler, accessible duct sections, drain pan, and supply vents. Sampling can determine whether the system is contributing to indoor mold levels.
