5 Reasons Why Mold Grows in a HVAC System

Since the HVAC unit plays a crucial part in the air that you and your loved ones breathe in at home, you should make sure that the emitted air is pure and has no elements or allergens that could potentially become health hazards.

Nothing can be worse for you and your family than breathing in mold spores every single day. The reason behind this is that mold is quite dangerous and can thus have detrimental health effects on anybody exposed to it. This article will help you get rid of mold in the HVAC system by explaining the main reasons why it grows there. This information will help you prevent or deal with the existing mold problem in your HVAC unit.

  1. Condensation Around the AC Coil

The major cause of mold in the HVAC system is condensation around the air conditioning coil. This usually happens when humid warm air passes over the cold AC coil. For instance, if your home basement area gets humid and the air ducts get cold, the warm air that blows on them causes water vapor to condense on the air ducts. This moisture content creates a perfect environment for mold growth. As long as other conditions are met, mold will without doubt start growing in your HVAC system.

  1. Organic Materials in the HVAC System

Another reason why mold grows in your HVAC system is the presence of organic materials. As the air conditioning system is in operation, dust tends to collect on both the air ducts and other parts of the unit. This dust contains all kinds of organic matter like dead skin cells, pet dander, and pollen. As we all know, organic matter provides incredible conditions for mold growth because it offers food for the mold. Combining organic matter and other conditions such as humidity and moisture, all these factors create a good place for mold growth.

  1. A Poorly Installed HVAC System

If your HVAC system is poorly installed, then you will probably be met with a hard time dealing with mold. This point mostly applies to the ductwork, which can be badly installed or leaky. When this is the case, the HVAC unit might not be in a position to deal with the mold spores in the surrounding air. Therefore, there is a very high chance that some mold spores will be stuck in the HVAC unit. When this happens, the mold spores will start growing and reproducing, creating a huge mold problem in your house. To avoid any problems, you need to repair or replace your HVAC unit the moment you notice it is not working correctly.

  1. Dirty Drip Pans

Most homeowners forget to clean their HVAC drip pans on a regular basis. If this is the case for you, then be ready to deal with a mold problem in your house. Drip pans have to be cleaned on a regular basis because they cause water to collect on them. This moisture creates an ideal hub for mold growth. You should thus clean your drip pans frequently or call in a professional to help you with the same.

  1. Mold in Other Areas

When you are dealing with a mold problem in other areas of your home, there is a very high chance that you will also have a mold issue in your HVAC system. This problem comes about because the HVAC system will draw in some mold spores from other areas into the unit. Since not all mold spores might come out, the remaining ones will start to grow and reproduce in the HVAC unit. If you want to get rid of mold spores in the HVAC unit, consider dealing with mold in other parts of your house.

Mold in the HVAC system is a common complaint among many homeowners. It can grow there and proliferate, making the occupants of the affected house sick without understanding the cause of their ailments. To make things even worse, a HVAC system blows air to the surrounding environment, making it one of the fastest ways to spread mold around a house.

To avoid any issues, you want to get rid of mold in the HVAC system as soon as possible. Luckily, this article has provided you with some common causes as to why mold grows in the HVAC system. You should thus be better placed to prevent some of these causes and keep yourself and those you love safe. If you are dealing with a serious mold in the HVAC system case, consider reaching out to an expert for assistance.
