HVAC System and Mold

HVAC System and Mold

Mold in an HVAC (heating, ventilation and air conditioning) system can lead to serious health issues. When an air conditioner or furnace is turned on, thousands of microscopic mold spores are blown out through the system and into the air we breathe. Mold in duct work can cause multiple health effects, including runny nose, eye irritation, coughing, congestion, asthma attack and skin rash.
