Is the air conditioning system (HVAC) affected by mold contamination?
The HVAC system is involved whenever there is an indoor air quality issue, either in a causational aspect (high humidity, drip pan, etc.) or spreading of spores. The entire HVAC system and vents should always be decontaminated. The EPA has approved use of MDF-500D in HVAC systems under EPA registration numbers 80346-4 & 80346-5.
