Mold growth in an HVAC system can be difficult to treat, and its presence is hazardous since the mold can spread throughout the building via HVAC ductwork. Here are some things to know about HVAC mold treatment. 

How Does HVAC Mold Growth Occur?

HVAC mold growth typically occurs when the parts of the system produce condensation that is not ventilated properly. The mold can rapidly be dispersed and take up root throughout the HVAC piping. 

What is the Treatment for HVAC Mold?

The first thing to do may be to get mold testing to find out the areas of the building that have mold present. This can point to which areas of ductwork have mold, since they may carry it to certain areas of the building more easily. An HVAC technician may need to evaluate the system to replace or repair certain parts of your HVAC system. There's also the component of killing existing mold with a strong chemical solution. An HVAC contractor may need to take apart the system in order to access areas that are contaminated. 

What Are the Main Culprits of HVAC Mold?

There are a couple of places that HVAC contractors look to root out mold problems. Air conditioning coils are one of the common parts where water can pool. If the coils are not cleaned properly, they can collect ice and water drips. Some systems come complete with a drip pan, and if this is continually overflowing, it can lead to humidity that promotes mold growth. If your air conditioning unit has a leak, this is another potential cause of water pools; check to ensure that the refrigerant is properly contained, and have an air conditioning repair and inspection done on a regular basis. 

Another issue is dirty air dampers or ventilation grills on your HVAC system. You may have a good ventilation setup that's being blocked by dust and other debris. Cleaning these areas may be a simple solution to prevent mold growth in the future. 

How to Prevent Future Problems?

Once you have your mold problem treated, you may be eager to avoid having a moldy HVAC system in the future. Treatment for the future starts now, since you can hire your HVAC contractor to install proper ventilation for yourair conditioning system and ensure that all of the parts are working correctly. You'll also want to schedule regular checkups, so that your HVAC technician can catch mold issues when they start, instead of after the problem has spread through your HVAC system.
