HVAC Mold and What Causes Mold in Ductwork


HVAC stands for Heating, Ventilation, and Air Conditioning System. Over the years, HVAC’s have evolved to meet the varied demand of households in Indianapolis. However, these devices are highly volatile to mold infection, and cleaning them is difficult, sometimes impossible. Mostly, HVACS are installed in the crawl spaces or attics, and making your way through these tiny spaces can be challenging and sometimes dangerous. Since there is not enough room to move around, a normal person trying to fix molds in HVAC Systems might get hurt during the process.

If you are worried about a mold infestation in your HVAC System, you should immediately contact professional mold removal companies in Indianapolis. In this blog post, we will look into the causes of mold infestation in air ducts and HVAC.

Causes of Mold Infestation in HVACC

There are several reasons for mold infestation in HVAC. Some of these reasons are easy to mitigate, while others are simply unavoidable.

1. Excess Moisture Build Up

Air ducts are responsible for transferring air to all the parts of the house. This air can be warm, cold, or mild. Whatever the temperature, air movement within an air duct causes water vapors to separate from the air. When this collects on the surface of air ducts, it forms moisture, a perfect ingredient for mold infestation in Indianapolis.

2. Movement of Contaminated Air

Air ducts have the responsibility of filtering air when they pass it around the house. This process of filtration keeps viruses and bacteria at bay. However, the filtration area tends to collect most bacteria that can quickly grow into mold. If your air ducts have not been cleaned in a while it has layers of dust accumulation which mold can use as its food source. In this situation, your best course of action is to contact professional mold removal companies in Indianapolis to fix this issue.

3. Your AC Is Oversized

This is a common problem, and you can easily fix this without involving any mold removal company. Larger AC’s can quickly cool a small area and turn off before dehumidifying, leading to excess moisture build-up, this is often referred to as short cycling. If you see any mold shortly after installation, monitor the time your AC takes to cool down your house. If it is too fast, get your unit replaced before it causes mold infestation throughout your home.

4. Setting Your AC on Very Low Temperature

Setting your AC at a very low temperature can also cause mold infestation in HVAC. The idea is to let the AC cool your house at its own pace. Don’t forcefully try to achieve desired temperatures by lowering the temperature. This is because your AC will shut down without dehumidifying and cause moisture to build up in the HVAC.
