HVAC Mold Testing

When occupants are reporting musty smells from vents, when allergy or respiratory symptoms get worse whenever the system runs, when there's visible growth around supply registers, after a flood or water event affecting the air handler, or before and after duct cleaning to confirm the work succeeded. HVAC mold testing answers the question that visual inspection alone can't: are the ducts spreading spores throughout the building.

Mold needs water, and HVAC systems condense water at every cooling cycle. Moisture detection during the visit checks drain pans, condensate lines, and the air handler enclosure for the water buildup that feeds mold growth, which is what guides where samples get taken.

Standard air testing samples the breathing zone of a room. HVAC mold testing samples the air system itself, looking at registers, ducts, and coils, to determine whether the system is the source of contamination or just moving it from elsewhere. Most thorough mold inspection and testing visits combine both.

Standard turnaround is 24 to 72 hours from when samples reach the state-certified lab. Expedited results are available when needed for tenant complaints, insurance claims, or HVAC contractor scoping decisions.
