Why Mold Might Form in Your Business Property

Protecting your Mcnair, TX, business from a mold invasion can be challenging, especially when it hides in places you least expect. Black mold is usually the most common and most widespread type of mold you might encounter, especially in your building’s heating, ventilation and air conditioning system. This might seem strange, as the system is enclosed by ductwork, but there are several reasons why mold might form there.

1. The Humid Environment
Your building’s HVAC system is a complicated maze of air ducts that foster a warm, humid environment, which is the perfect setting for mold growth. Most kinds of fungi thrive in such a setting, and if your building is naturally humid, this may only increase the problem. Taking steps to decrease moisture can lower the risk of mold growth in your HVAC ducts.

2. Incorrect AC Unit Size
When your air conditioner is either too large or too small for the building it cools, it can encourage mold growth. For example, a system that is too large may run in shorter cycles and fail to dehumidify the building’s air, which may increase moisture in the ductwork. Many types of fungi, including black mold, can thrive when this occurs. Over time, you may notice a musty, unpleasant smell when you use the system as the growth spreads and grows larger.

3. Duct Leaks
If your building’s HVAC ducts have leaks, this can allow warm air to seep in and meet with the colder air inside the system, which creates a moist environment where mold can grow. Calling in a mold mitigation and removal service to clean ducts and repair the leakage may improve the way your system operates and reduce the risk of mold growth.
Black mold and other types of fungi in your HVAC system can have a negative impact on your Mcnair, TX, business. Knowing what might cause this problem can help you prevent and recognize it so you can reach out for help before it gets worse.
