Mold is everywhere, and while it’s harmless outdoors, it can be a big problem when it starts to develop indoors. Mold is a common problem in HVAC systems, especially when there’s poor humidity control.

While there’s no way to completely eliminate mold and mold spores in your home, there are ways to control its growth. Read on as Dittmer Air and Heat, your restaurant refrigeration expert, discusses how mold grows in HVAC systems and different ways to deal with it.

How Mold Forms in HVAC Systems

Mold thrives in warm, moist environments, making HVAC units vulnerable to this issue. Mold growth usually occurs in the air ducts. When cold air passes through the ducts and the surrounding environment is humid, water vapor can form within the system. This creates moisture, which when combined with organic matter like dust, dirt and pollen will eventually lead to the formation of mold.

Mold can also be a problem on your air conditioner’s coil. When warm air blows over this component, excessive moisture may form, thus encouraging mold growth. This excess moisture drips into the drain pan, where dirt and mold spores can then collect.

Ways to Control Mold Growth

Fortunately, there are several ways to prevent mold growth in your HVAC system. Take note of the following steps for your next HVAC air conditioner repair and maintenance:

Replace Air Filters Regularly – It’s a smart practice to check your air filter monthly and clean or replace it if there’s dirt buildup. If you have pets or if anyone in your home has asthma and/or allergies, we suggest changing the filters every six weeks to ensure that your indoor air quality stays up to par.
Use an Inhibitor. EPA-registered, HVAC-approved inhibitors can help prevent mold from developing in your HVAC system. Follow the manufacturer’s instructions when applying them to the components of your heater and air conditioner.
Fix Leaks Promptly. Contact your trusted contractor right away if your HVAC unit isn’t draining properly. They’ll seal off the pipes and ducts to prevent mold from spreading to the rest of the system.
