What Mold in Air Ducts Could mean for Commercial Buildings

2/9/2021 (Permalink)

Mold frequently grows on construction materials for commercial buildings. It thrives in hidden, dark spaces with favorable humidity levels and hosts that provide it the nutrients it needs. Mold spores will settle and develop into colonies in any areas that provide these conditions. Hiring an HVAC cleaning service at least twice a year is recommended for commercial buildings. It is common to find fungus growing inside of HVAC systems on:

• AC evaporator coils
• The drip pan
• Inside air ducts
  
  

If you find mold around your commercial property, it is likely there is mold inside of your HVAC system as well. Here's what mold in the HVAC system could mean for your commercial building:

Mold Spores Will Circulate When the HVAC System Turns On

Mold can be found feeding off the dust in your HVAC system. This is because air ducts provide a suitable environment for fungus to thrive. This mold will release mold spores that circulate into every room of a commercial building when the HVAC system turns on. This makes them more likely to attach themselves to the natural construction materials of the building. Regular HVAC cleaning will clear your air conditioning system of dust, preventing mold growth. Cleaning vents frequently will also aid in mold prevention.

Mold in Your Air Ducts Will Cause Unpleasant Smells

A key indicator of mold being circulated through the building is an unpleasant, musky smell. When mold spores are circulated through air vents it makes them more likely to grow on other materials that provide the right nutrients, including water damaged wood or drywall. The smell coming from these materials is often described as humid and earthy.

Mold spores only take about 48-72 hours to develop into colonies. If you have found mold on your property, it is crucial to address it right away by calling an HVAC cleaning service. This will improve the overall air quality in your building and prevent mold damage.
