The HVAC system is a system that many homeowners hardly think about when it is working properly.  However, the HVAC system is one of those systems that can cause a mini crisis if something goes wrong.  Several of the component parts of the HVAC system generate moisture in the form of condensation and when the system draws in humid air, this can result in further buildup of condensation inside the air ducts.  If this moisture continues to build, you will eventually have mold in your air ducts.  Mold growth in the air ducts must be removed immediately because the HVAC system will disperse the spores throughout your home each time it runs the heating and cooling.

Problems that Lead to Mold Growth in Air Ducts

You must call a mold remediation professional immediately to remove mold from your HVAC system.  The best way to prevent mold growth in your air ducts is to react to issues that cause moisture buildup.  The following are common problems that result in excess moisture in the HVAC system:

• Poor Dehumidification: The HVAC system must effectively dehumidify. Poor dehumidification causes an increase in condensation that leads to mold growth.


Moisture in the air ducts leads to mold growth.

• Leaks: Leaks anywhere in the air ducts cause suction within the building that draws in humid air from the outside. Excess humidity increases condensation throughout the home, as well as the risk of mold growth.
• Poor Drainage: If the HVAC systems does not effectively drain the condensation, it will drip or leak which leads to water damage and mold growth.

Preventing Moisture Buildup with HVAC Maintenance

If you notice any of the above-mentioned problems with your HVAC system, the following HVAC maintenance tips can help.

• Seal Air Duct Connections: Check the seals between the air ducts and fix any broken seals. A break in the seal allows outside air and moisture in.
• Prevent Overflow of Condensation: Do what you can to prevent condensation overflow from the drain pan. Wipe off the condensation from the air ducts, cold pipes, diffusers, valves, and air handling units.
• Reduce Humidity: Make sure your kitchen, bathroom, laundry room, and other high moisture areas are properly ventilated.

Mold in the air ducts is a serious problem because the HVAC system can easily spread mold growth and increase health risks by dispersing the spores.  You should never try to remove mold from your air ducts yourself, contact a mold removal professional.  These professionals have the expertise and the proper equipment to safely remove mold from the HVAC system.  You can also help prevent condensation buildup and mold growth in the HVAC system with professional air duct cleaning services.
