Preventing Moisture in the Air Ducts12/16/2013 Back To Blog
The air duct system should have no moisture in it. Keeping moisture out of your ducts is the most effective way of preventing biological growth such as mold from developing. Moisture can be caused by leaks in most cases; inadequate servicing and installation can also result in moisture. Studies have shown that condensation occurs when the specified dew-point temperature is higher than the surface temperature of the air around the air conditioner, resulting in a buildup of moisture. When there is condensation and humidity in the ductwork, it is very probable that there is also the growth of mold. Here are some basic instructions to assist in keeping your ducts moisture-free.
Inspect Cooling Coils
The most effective way to stop moisture is by fixing duct leaks immediately upon discovery. Cooling coils are designed to extract the water out of the air; be sure that they aren’t causing the contamination of moisture. The condensation pan should also be functioning properly. Inspect around the cooling coils for wet spots and damp areas. Also, make sure that there is no standing water in the HVAC ductwork. This can cause major issues.
In all of the areas that aren’t air conditioned, there should be a secure seal on the ducts. This helps keep moisture out, which can affect the performance of your ventilation system. Inspect and make sure the heating and cooling system is insulated correctly also because this protects against condensation. The ducts should all be sealed at the connecting joints. If you are installing a unit that is brand new, be mindful that the appropriate size is used. The wrong size will make the unit turn on and off more frequently; this causes poor removal of moisture in the system. Check your air duct system to ensure that it can handle condensation proficiently.
