HVAC Systems can produce mold that can be harmful to a family’s health. Mold can accrue on many different areas of an HVAC System and then travel through the system and be dispersed in the air of one’s home. Knowing which parts of your HVAC system to check for mold is important to maintaining the health and comfort in one’s home.
First one must understand how mold can become a problem with an HVAC system. Mold needs water and the right temperature to grow as well as a food source. The best way to avoid indoor mold with your HVAC system is to have a unit that is properly designed as well as installed and maintained.
HVAC systems are a significant source of moisture for mold and this is why mold tends to grow on the various parts of the system. The system then has the ability to transport the mold to the home. If a HVAC system is not designed well or maintained and in good working order, it can become a support system for mold growth that will be harmful for your home as well as your health.
A homeowner can conduct a HVAC system assessment that will help look for mold on your system.
Below is a checklist of areas to look over for mold spores:
Drain Pans/Coils: The cooling coils of your unit dehumidify the air so they will condensate water to the drain pan. This can accumulate standing water if the drain pan was not designed well or maintained. This could cause a breeding ground for mold. The drain pans must be cleaned on a regular basis and sloping should be achieved to create a good drain of the water accumulated.
Humidification/dehumidification equipment: Duct linings are not supposed to be wet from any type of water source. This could cause mold spores that would be transferred throughout the home. Wet surfaces of this equipment should be drained on a regular basis to prevent mold.
Air Filters: Everyone knows they should change their air filters on a regular basis. However, it is a good idea to turn off fans when changing out the filters so there is no contamination in the air. Filters need to fit tightly into the return and remain dry.
Homeowners can take the above steps to prevent their HVAC system from taking on mold. These preventative measures can help maintain a healthy home and a functioning HVAC system.
