For mold to thrive, two things are needed: warmth, and moisture. An ideal climate for mold to grow would be an area that is warm and humid and is poorly ventilated. Areas like the bathroom, attic, or basement can be more prone to mold growth. 

What many people may not know is that air ducts are another space susceptible to mold. Keep reading to find out how mold grows in air ducts, how to prevent it, and how to remove mold in air ducts!

Can Mold Get In Air Ducts?

An HVAC system is made up of various components that allow for heating, ventilation, and air conditioning. Different methods can be used to heat the air that circulates into your home, and an air conditioner is used to cool the air for your home. Whether the air is warm or cool, it will be forced through the air ducts and vents throughout your home.

Since mold needs moisture to thrive, there are some important things to know about your HVAC system and how it works. When your home is being cooled during the hot summer months, the AC unit pulls the air from outside and cools it as it brings it into your home. 

The moisture in the air can collect as condensation within the air ducts themselves. If the condensation or water droplets don’t evaporate, they will continue to collect allowing for mold to grow. See below for some common causes of mold in air ducts.

AC unit is too big

If the unit is too big, it can cool a smaller space too quickly not leaving enough time for the humidity to be removed from the air. The moisture can be left to build up allowing mold growth to occur.

Temperature set too low

Supercooled air being forced into warmer air can cause any moisture in the warmer air to condense. If this occurs, moisture will form around the air vents allowing for mold to grown and get into the ducts.

Leaky air ducts

The temperature difference between the warm outside air and the cooled air in the ducts can cause moisture to condense inside the ducts. When mold is within the air ducts, it can be spread throughout your home from the circulated air.

How To Know If You Have Mold In Air Ducts

Initially, it may be difficult to determine if mold is within your air ducts. Mold spores are microscopic, and most often if you can see mold it has already grown into a colony and spread throughout your home. Thankfully, there are other signs to be aware of aside from visual mold spots.

Odors - Mold can produce quite a noticeable musky smell. Most people have smelled mold at some point and can pick out the smell when it is present. If you notice a musky, wet, rotten, or musty odor throughout your home, there could be signs of mold in your air ducts. If the odor is stronger while the AC is running, it is even more likely there is mold.

Visible Mold - Seeing patches of mold in drip pans, around the air vents, or in the ducts themselves. If the mold is visible, surely spores are being spread throughout your home and it is imperative to get it taken care of right away.

Mold In Air Duct Symptoms

Dealing with mold anywhere in your home can be tricky. It is a finicky substance and most regular household cleaners will not effectively kill the mold. In general, it is wise to have a professional come for any mold removal project. Check out the page from the EPA about air duct cleaning.

If you do notice mold on or around your vents, you can create a solution to help prevent more damage or spread while you wait for mold removal specialists from Rock Emergency. Using 1 tbsp of laundry detergent, ½ C of baking soda, and 1 C of water can be combined as a cleaning solution for around your vents.
