Causes Of Mold In Air Vents

Causes Of Mold in Air Vents

High humidity and moisture buildup is a common cause of mold in air vents and ducts. However, moisture is not the only cause of mold growth. There are many other reasons why your AC vents have mold growth inside. These causes are:

Dust Buildup

If you’re not cleaning your air vents and grills, the dust can start accumulating. This increases the chances of mold growth. When mold spores get ample dust and moisture, they grow rapidly.

High Humidity Levels

If you live in a highly humid climate, the chances of mold growth around the house become very high. If there’s mold growing on the ceiling, under the floors, or in the walls, the mold spores will get trapped in your air vents and start reproducing.

Water Leaks

Water leaks anywhere in the house allow mold to grow. If there’s a leak in the pipes in the walls or the roof surrounding air vents, the mold will grow in those areas. It will eventually spread to the air ducts and vents. Fix any leaks before it’s too late.

Poor Ventilation

Poor ventilation of the house leads to the retention of moisture. The air gets trapped in the house and when you turn the AC on, the same air starts circulating in the house. This leads to moisture buildup and eventually causes mold growth in air vents and AC ducts.

To prevent mold growth, make sure that you pay attention to potential mold-causing factors. Keep an eye on your vents and terminate mold in hidden spots. Regular maintenance of your air vents can help you detect mold growth in the early stages. If your air vents are already mold-affected, take quick action for mold removal.
