Three Signs of Black Mold In Your HVAC System

Mold spores are living microscopic particles that attach themselves to hosts and develop into colonies. There is no commercial facility in Westmoreland Heights, TN, that can be cleared of mold spores. However, there are ways to prevent mold growth such as:

• Keeping humidity levels at or below 40-60%
  
• Cleaning frequently
  
• Addressing water damage immediately
  
  

Your HVAC can be a major contributor to the circulation of mold. 

1. Mold on the Evaporator Coils
Black mold colonies manifest as dark green, black, or gray-colored slime. If you notice this type of fungus developing on the evaporator coils and the drip pan, it is likely mold spores are being circulated. Mold can originate in the condenser unit and travel through the air ducts.

2. Mold on the Air Vents
A fungus that is circulated through the HVAC system will manifest as black and green spots on the air vents throughout the facility. These spots are difficult to scrub off and can corrode the air vent. If you find mold spots on the vents, it is likely mold colonies are developing inside of your HVAC.

3. Musty Sell When You Turn On the HVAC System
A musty smell that becomes stronger when you turn on the HVAC system is a clear indicator that there is mold growing inside of the ducts. The air ducts provide fungus with the humid and dark conditions necessary for it to thrive while the accumulated dust provides a source of nutrients. The colonies will then release more mold spores into the air and contribute to a mold problem.
If you believe you have black mold inside of your HVAC system, contact a professional HVAC cleaning service to aid in clearing it. Clean ducts are essential to keeping your building mold-free. A problem that has persisted and spread throughout the building should be addressed with mold remediation services.
